Through Hole Resistors

Through hole resistors, also known as leaded resistors, refer to mounted type resistors with leads extending through the metal mounting clip, and is soldered and mounted on the PCB. By adjusting the length of lead wire, the conductor pattern space for PCB design can be optimized and the reliability of mounting can be improved. WHC750FE is a type of leaded resistors with a power rating of 0.75W and a tolerance of ±5%. It is characterized by high power, low noise, excellent temperature coefficient, and high reliability and stability. This article will discuss the applications and working principles of WHC850FE.

Application Field of WHC850FE

WHC850FE is widely used in consumer electronics, personal computers, medical devices, automotive electronic, test and measurement, communication, and other industrial applications. It is suitable for the circuits that are able to tolerate large current, and is mostly used in linear applications, such as power supply, motor, and lighting. The working principle of WHC850FE is similar to that of other through hole resistors. It has a variety of characteristics that can be used to facilitate the design and component selection in different applications.

Working Principle of WHC850FE

The WHC850FE works by using its lead wire to transmit a signal. This signal may come in the form of an electrical current, or a thermal energy. When an electrical current passes through the resistor, it induces a voltage drop between two points on the wire. This voltage drop is proportional to the resistance of the resistor.When a thermal energy passes through the resistor, the lead wires heat up, and this heat builds up in the resistor until the temperature of the resistor reaches a steady state. This steady state is known as the temperature coefficient. When the temperature coefficient is reached, the lead wire will begin to dissipate heat and cool down to its original temperature, thus completing the resistive cycle.The main component of WHC850FE is its resistor chip. The resistor chip is composed of two parts, the first part is the substrate, and the second part is the wiring material. The substrate is made up of titanium dioxide, while the wiring material is made of silver (Ag), aluminum (Al), platinum (Pt) or gold (Au), depending on its required function.The resistor chip is printed with a layer of resistor ink in order to achieve a certain resistance, and the resistance of this ink is controlled by adjusting the length and width of the resistive paths. To measure the resistance, current is applied to the resistor and the voltage across it is measured. The voltage corresponds to a certain resistance while the current corresponds to the power.

Conclusion

The WHC850FE is a type of through hole resistors with a power rating of 0.75W and a tolerance of ±5%. It is characterized by high power, low noise, excellent temperature coefficient, and high reliability and stability. It is widely used in consumer electronics, personal computers, medical devices, automotive electronic, test and measurement, communication, and other industrial applications. The working principle of WHC850FE is similar to that of other through hole resistors, and is composed of one substrate and one wiring material, where the resistance is controlled by adjusting the length and width of the resistive paths.
