The resistance value of a fixed resistor is fixed, and the resistance value is its nominal resistance value. Due to its wide range of uses, there are many types of fixed resistors, which are generally classified according to their constituent materials and structural forms. Different types of fixed resistors have both common resistance properties and different characteristics.
Mainly used as high resistance high voltage resistor. Its use is the same as that of high voltage resistors.
Wirewound resistors have high resistance value accuracy, low operating noise, stable and reliable, and can withstand high temperatures
The mixture of carbon black, resin, clay, etc. is pressed and made by heat treatment.
Cement resistors, resistors potted with refractory mud, with special non-flammable heat resistance
