3W Metal Film Resistors 3 Watt 1% Tolerance 1 ohm - 1M MANY SIZES AVAILABLE

 

 

Resistor is generally directly called resistance in daily life. It is a current-limiting element. After the resistor is connected in the circuit, the resistance value of the resistor is fixed, usually two pins. It can limit the current through the branch it is connected to.

The metal film resistor is one of the film resistors. It is made by using the high temperature vacuum coating technology to tightly attach the nickel chromium or similar alloy to the surface of the ceramic rod to form a film. After cutting and adjusting the resistance value, it can reach the final required precision resistance value. Then it is cut with appropriate connector and coated with epoxy resin for sealing protection on its surface.

Product application: Metal film resistance is a widely used resistance so far. Compared with carbon film resistance, this kind of resistance is small in size, low in noise, good in stability, but high in cost. It is often used as a precision and high stability resistor. Because it is a lead type resistance, simple and lightweight in structure, convenient for manual installation and maintenance, it is often used in various household appliances, communications, instruments and radio electronic equipment.
