A thermistor is a type of temperature sensor made from semiconductor materials. The word "thermistors" is a combination of "thermal" and "resistor," which helps give a clue to its function- to change its electrical resistance in response to changes in temperature.

Integrated Circuits (ICs) are compact devices that contain multiple transistors, diodes, resistors, and capacitors on a single semiconductor material. They have revolutionized the electronics industry by enabling the miniaturization and integration of various electronic components into a single package. ICs offer several advantages over traditional electronic components, including smaller size, lower cost, higher reliability, and improved performance. There are various types of ICs, including Analog ICs, Digital ICs, Microcontroller ICs, and Memory ICs, each serving specific functions and applications. The widespread use of ICs has enabled the development of many advanced electronic devices and systems, including computers, smartphones, and automobiles.

The resistor is one of the most important electrical components used to protect electrical circuits from damage. It is a passive two-terminal electronic component that offers resistance to the flow of electrical current. Continue reading to learn the maximum working voltage across a resistor and how to calculate it.

Power factor correction (PFC) is an important process for adjusting energy levels in electrical devices. This value is particularly important for manufacturers who sell electrical equipment in the European Union, which determines the minimum power factor or maximum level of harmonics for electrical products sold in the EU.

Some people might think the decoupling vs. bypass capacitor comparison is futile, assuming the terms are synonyms, although they aren't. While a bypass capacitor removes unwanted noise from an electronic system or cables, a decoupling capacitor's job is to create a low-impedance path for the AC signal.
All types of capacitors are reactive devices but vary in resistance levels to signals based on frequencies. Both provide high transient current to an integrated circuit while minimizing power ripples.
Once current passes through the collector and emitter, it can either flow through a resistor or a bypass capacitor. Current moves in the path of least resistance, so the value of the resistance in the bypass capacitor needs to be 1/10th the value or less of the emitter resistor.
When comparing the decoupling vs. bypass capacitor, it's important to note that electronics manufacturers often favor small components. However, larger value capacitors make the DC signal purer while allowing more AC to ground.

The major differences between resistors and capacitors involve how these components affect electric charge. While resistors apply resistance to limit current flow, capacitors store energy in an electric field until it's needed. Adding resistors and capacitors in series increases the impact of their respective functions. That means adding resistors in series increases resistance, while adding capacitors in series increases capacitance. Resistors and capacitors are commonly found in radio communications equipment and logic circuits, along with inductors.
