Through Hole Resistors

Through hole resistors are widely used in electronic and electrical circuits for a variety of applications such as amplifying signals, supplying power and as part of more complex circuitry. In this article we look at the application field and working principle of a specific type of through hole resistor – the FMF50SFTE52-560K.

What is the FMF50SFTE52-560K?

Working Principle

The working principle of the FMF50SFTE52-560K is simple. It consists of two parts: the lead frame and the resistor. The lead frame is an electrically conducting component and serves as the electrical connection point between the device and the other components in the circuit. The resistance value of the resistor is determined by the resistor material that it is composed of, and will resist the flow of current when a voltage is applied across it. When a current is applied to the device, the resistor heats up due to the resistance.

This heat is then dissipated into the surrounding environment by the thermally enhanced thick film resistor and the heat-transferring elements in the package. The device is designed to be efficient and reliable in high-power applications, and the wide operating temperature range makes it a great choice for extreme environment applications.

In Conclusion

The FMF50SFTE52-560K is a powerful, precision-molded, through-hole resistor with high power-dissipation and a wide operating temperature range. It is suitable for applications such as power supply control circuits, motor drive circuits, power supply voltage support circuits, current detection and protection circuits and motor control circuits. Its working principle is simple and it is designed to be efficient and reliable in high-power applications.
