WEET MOF Cutted and Capped Resistors Rods

WEET Resistors Classified by material

A、 Wire wound resistors are made by winding resistance wires into resistors using high resistance alloy wires wrapped around an insulating skeleton, and coated with heat-resistant glaze insulation layer or insulation paint on the outside. Wire wound resistors have a low temperature coefficient, high resistance accuracy, good stability, heat and corrosion resistance, and are mainly used as precision high-power resistors. The disadvantage is poor high-frequency performance and large time constant.

B、 Carbon composite resistors are made by pressing carbon and synthetic plastic.

C、 Carbon film resistors are made by coating a layer of carbon on a ceramic tube and depositing crystalline carbon on the ceramic rod skeleton. Carbon film resistors are currently the most widely used resistors due to their low cost, stable performance, wide resistance range, and low temperature and voltage coefficients.

D、 A metal film resistor is made by coating a layer of metal on a ceramic tube, and the alloy material is evaporated onto the surface of the ceramic rod skeleton by vacuum evaporation.

Metal film resistors have higher accuracy, better stability, lower noise, and temperature coefficient than carbon film resistors. Widely used in instrumentation and communication equipment.

E、 A metal oxide film resistor is made by coating a layer of tin oxide on a ceramic tube and depositing a layer of metal oxide on an insulating rod. Due to its inherent nature as an oxide, it is stable at high temperatures, resistant to thermal shock, and has strong load capacity. Depending on its application, it can be classified into general, precision, high-frequency, high-voltage, high resistance, high-power, and resistance networks.
