What Are Thin Film Chip Inductors?

Thin film chip inductors are a type of inductor manufactured using thin film technology. The manufacturing process involves depositing thin film materials on a substrate and forming a spiral coil, allowing the inductor to achieve a more compact and lightweight design. This design makes thin film chip inductors an ideal component in electronic devices.

Nothing is New.

I chanced upon yet another amplifier with a revolutionary power supply. This one bragged about having a choke in a transistor amplifier PS. That is FN old school as in 1940s! I think I heard one hardware Guru state that amplifiers are just ways to listen to the power supply, or something like that.

Unless you are old, or had / have a tube power amp and are a real nerd you probably do not know what a choke is in electronics. They are inductors. Inductors are coils of wire in loops. Loops of wire create and react to their own magnetic field. Inductors will pass DC and low frequency signals but block higher frequencies. When used as speaker cross overs and in outputs of amplifiers the are called inductors. When used in power supplies they are chokes.

OK that is a massive simplification, but objectively true. Chokes are set with very high values of millihenries to stop line noise. They achieve that by winding the loops around a metal core. Chokes look like transformers but they aren't. They are the classic top part in a Pi filter. Stretched between two capacitors they filter out any RF or buzzing or even AC frequency. In that case the are aimed at blocking the relatively low AC wall current signal. That is really low in audio terms 60 Hz in my country and 50 hz in other places. They will restrict audio level signals.

They are ideal for the "power supply is a filter" approach. All classic tube amplifiers had them. Part was that very high voltages and large capacitors are a tricky combination and that is what tube amps need and have. Add a choke to make it quieter. They work. Less hum, but they have other effects too. They restrict flow, that is what the word choke means.

I think it is asinine to use in solid state amplifiers. What a choke does is restrict current flow. Tube amps are mostly voltage beasts. What you need in solid state is free flow of current. Give me amperes! Yes it makes it quieter, but it also restricts and effectively compresses dynamics. My mill pond analogy is good here. The mill can draw as much water from the pond reservoir as it needs if the pond is large. If you have two smaller ponds connected by a small stream the water surface in the second pond may be calmer, but there is less to draw on it any one time.

There is also a similar vein with the CRC filter where there is a resistor between two capacitors that has a very similar effect. I have seen that in a few tweaking products. My objections are the same.

This may be to try to give people "tube sound" by mimicking tube design in solid state. Or it may be to try anything to distinguish your product from others. There are other ways. I recall that testing group doing a review of an Audio Research solid state amplifier and it had relatively high distortion because it had low levels of feedback. The distortion was of the harmonic type common in tube hardware. That device is beautifully built, but intended for a particular market that likes a certain voice.

My experience includes a pair of Tube amps that had chokes and I enjoyed the voice they had. I wanted and got better.

When I built the Franken-amp I tweaked the power supply. It is split right and left after the huge transformer. The main capacitors are biggish and bridged with large foil caps to block RF garbage. The biggest thing is I have a huge pond. When it is not connected the sound is very good as in a high end solid state amp from the 70s. When One Farad of extra capacitors is plugged in the effect is almost dramatic. The background goes black. The dynamics are huge. So yes my power supply sounds fine.

So here is a new thing that is an old thing. The parts bin is not that different in what type of things you can use. For the most part there are really good quality pieces out there.

Funny that even in my old all tube preamp and my current hybrid preamp there is not a choke in sight.

How the Electronics Industry Uses Different Types of Inductors

In electronic component products, inductance plays a pivotal role in maintaining the normal operation of electronic equipment. Inductors are now widely used in high-power electrical appliances, spike blockers, radio frequency devices, signal shielding and other equipment. The following are common types of inductors and their typical uses:

coupled inductance

The magnetic circuits of the coupled inductors are shared and affect each other. Coupled inductors are often used in transformers, especially as feedback mechanisms for voltage rise and fall or isolation. Including transformer.

Winding Core Inductance

Core-wound inductors are characterized by having one or two cores. The number of windings is proportional to the increase in inductance and capacitance. It should be noted that there is a valid trade-off between high inductance and maximum operating frequency.

Power Inductors

Power inductors typically come in a variety of powers and sizes. These inductors carry currents ranging from a few amps to tens of amps. Because power inductors can withstand large currents, they can generate strong magnetic fields. At the same time, in order to prevent these magnetic fields from generating unnecessary noise, corresponding shielding measures need to be taken.

RF Inductors

RF (radio frequency) inductors typically operate in high frequency environments. This type of inductor usually has high resistance and low current rating. Because of the operating frequency of the inductor, it is important to reduce multiple sources of loss, so most RF inductors use an air-core construction. The reason for not using ferrite is that its losses increase during use.

choke coil

Chokes block high-frequency pulses while letting low-frequency pulses pass. Usually divided into two categories:

• Nanocrystalline core power supply and audio choke coils.

• RF choke coils using powdered iron cores.

Soft Ferrites Applications

Soft Ferrites Applications Ferrites are polycrystalline oxides manufactured by ceramic technology and belong to a class of materials that exhibit the technically useful property of ferromagnetism. In a ferromagnetic material, magnetism occurs under the influence of an externally applied field. On removals of this field, material returns to its non-magnetic state. This behaviour is termed as…

Ceramic Green Sheet Market - Forecast(2022 - 2027)

The ceramic green sheet market size is projected to grow at a CAGR of 2.9% from 2022-to 2027. A ceramic green sheet is used in the formation of a sintered ceramic substrate, which contains ceramic powder and photosensitive resin composition. Ceramic sheets are formed from ceramic powders like alumina, zirconia, aluminum nitride, zirconia, and silicon nitride while ceramics are formed by barium titanate, boron nitride (BN), and alumina. It is majorly used in air conditioners which are placed for heat exchange and thus keep the room cooler in less time. It is also used in semiconductors in automotive and electrical industries due to its flexible shape capability and bonding applications, which is driving its market growth. Many countries experienced a setback in the production and development of applications, including the electrical and electronics industries, as a result of COVID-19. However, many ceramic manufacturers declared their operations essential for industrial applications such as televisions and smartphones while the country was in lockdown.

What Are SMD Inductors?

SMD inductors, also known as surface mount inductors, are components embedded in circuit boards using Surface Mount Technology (SMT). Unlike traditional through-hole inductors, SMD inductors are better suited for highly integrated circuit boards and automated production processes. Their characteristics of being compact, lightweight, and high-performing make them an indispensable part of modern electronic devices.

#your girl did NOT finish and what she did do was almost certainly not correct #for one problem at least. probably two #im mad i tried to do the last problem instead of finishing up the inductor power one bc i probably could have gotten full points for that i #i had gone back to it and now that’s an automatic 10% knocked off and i probably won’t even get partial credit for the last problem <3 #it’s fine!!#<- i did do half the inductor problem and am p confident it was right but then i got to part ii of it and was like oh shit i need to see #what else is after this bc the clock is ticking i’ll just wrap this up real quick later but then prof collected our exams immediately after #end of class which he didn’t do last exam :/#personal #the engineering chronicles #also pissed bc my issue is that i ran out of time not that i didn’t know how to do the stuff. which makes it sm more frustrating like if i #had just been faster.#whatever. onward now to exam prep 2 electric boogaloo (physics)
