Working Principle

The WW12FT38R3 is composed of a metal housing with three metal contacts, two of which are insulated from the other. Through the application of voltage, current is sent through the three contacts, limited by the resistance determined by the resistive material inside the component. The resistive material, typically a metal or ceramic material, restricts the flow of electrons in the circuit, thereby providing the necessary electrical resistance to regulate voltage, current, and thermal management. The component also has capacitor plates, which are connected in parallel with the resistor, providing a degree of protection against power surges and voltage spikes.

The WW12FT38R3 is a robust component with optimized performance capabilities to meet a wide range of demanding applications. Its combination of resistive and capacitive elements ensures it can adequately protect circuits while regulating voltage, current, and temperature. With its low inductance and wide temperature range, it is an ideal choice for a variety of industrial, automotive, and instrumentation applications.
