Introduction

Through Hole Resistors are Resistors which are inserted into plated through holes on a printed circuit board. They are usually used when there is a need for a larger surface mount resistor in order to provide higher power dissipation or to more precisely control operation. They are also sometimes used to provide wiring access for routing signals inside of a circuit board. One of the most popular types of Through Hole Resistors is the PSM400JB-1K.

What is the PSM400JB-1K?

The PSM400JB-1K is a fixed, thick-film resistor with a metal end termination. Its ultra-small size and low temperature coefficient make it ideal for use in a wide variety of applications. It is also highly reliable and has a long life expectancy. The PSM400JB-1K is available in a wide range of tolerances, ranging from ±0.25% to ±5% and is available from 0.5 W to 5 W power ratings.

The Application Field of PSM400JB-1K

The PSM400JB-1K is commonly used in a variety of industrial applications, including automotive, medical, and consumer electronics. It is suitable for use in power supplies, thermostats, relays, inverters, and switching regulators. It is highly reliable and long-lasting, making it an ideal solution for applications in harsh environments. Additionally, this resistor can be used for signal filtering in sensitive electronic circuits and as a current limiter in AC and DC power circuits.

Working Principle of PSM400JB-1K

The PSM400JB-1K works on the principle of electrical resistance. This resistor contains a small amount of resistive material, usually metal or carbon, that opposes the flow of electric current through it. The current is “resist” and this generates heat, which is dissipated to the surrounding environment. The amount of resistance depends on the type of material used and the size of the resistor. The resistance of the PSM400JB-1K is fixed, meaning it cannot be adjusted after it is manufactured.

Conclusion

The PSM400JB-1K is a Through Hole Resistor that is commonly used in a range of industrial applications due to its small size, low temperature coefficient, and high reliability. Its working principle is based on electrical resistance, and it has a fixed amount of resistance. It is available in a range of tolerances and is suitable for use in AC and DC power circuits.
