Through Hole Resistors

Through hole resistors are resistors that are mounted through a hole or pad in a printed circuit board (PCB). They have been around for decades and are still used in many electronic designs and applications. The WLAR100FE is an example of a through hole resistor.

WLAR100FE Application Field

The WLAR100FE is widely used in various fields. It is an excellent choice for applications in remote sensing, instrumentation, and interface systems, as it provides a 0.1 Ohm load precision. In telecommunications, it is often used in RF and base station relays for impedance matching and signal conditioning. It is also suitable for use in mobile networks or satellite communications systems, especially where good temperature stability is required. In the automotive industry, it is used as an over-voltage protection device for controlling voltage levels in electronic circuits.

Working Principle

The WLAR100FE works on the principle of resistive heating. The resistor is designed to dissipate a certain amount of power by producing heat due to applied voltage and current. The amount of power dissipated depends on the magnitude of the voltage and current, as well as the resistance of the resistor. When a voltage is applied to the resistor, current will flow through it, creating heat, according to Ohm\'s law. The amount of heat produced is proportional to the resistance of the resistor, as well as the square of the current. As resistance increases, more heat will be generated and vice versa.The WLAR100FE has an exceptionally low resistance value, which allows direct current (DC) to flow through it at a steady rate, producing minimal heat. It is ideal for applications where load current and power dissipation need to be tightly controlled.

Conclusion

The WLAR100FE through-hole resistor is an ideal choice for various applications where precise load current and power dissipation is required. Due to its low resistance value and excellent temperature stability, it is particularly suitable for use in telecommunications, instrumentation, and automotive applications.
