Power resistors power resistors role in the power circuit resistance: resistance is small, the current large ripple resistor in the circuit, the current is inversely proportional with the voltage that is Ohm's law, resistance is proportional with the voltage, current with inversely. In the circuit is mainly mainly absorbed power, acting as a buffer ripple resistance selection, delayed start is turned on, the general use of aluminum shell resistance, heat points, or power resistors to cool ... · What is the resistance is ?? but rated power value is high, generally more than 0.5W, the big one hundred watts or more can be achieved. Heads are also great. Material with carbon film resistors, metal film resistors have different, generally corrugated cement resistance wirewound resistors or resistor manufacturers, as well as the resistance of the metal shell package. Price than conventional power resistors 1 / 4W resistance is much more expensive, generally used for power supply, power amplifier ... to the product are: carbon film resistors, metal oxide film resistors, precision metal film resistors, high voltage resistors, high-power wire resistance, braking resistance, high pressure resistance, water resistance, braking resistance, corrugated resistors, cement resistors, ladder (ship) type aluminum resistance, RX24 gold aluminum resistors, Crowbar (wind power converters) resistance, milliohms (manganese copper) resistance, load resistance box (cabinet), aroma body resistance heating, and various other special high-profiled ultra-low resistance resistance. Our products are widely used in national defense construction, the state's key scientific research projects and railway, metallurgy, inverter, servo systems, wind energy, solar inverters, welding machines, high and low voltage electrical, power, numerical control, instrumentation, home appliances and other industries ... 1, carbon film resistors carbon film resistors are separated organic carbon at high temperature in a vacuum oven, and then the carbon is deposited on the surface of the ceramic substrate is formed (the size of the resistance by varying the thickness of the carbon film has a certain resistance or length available) of carbon (resistor), and finally to the appropriate connector after cutting thin and coated with epoxy sealed to protect its surface and has produced a ripple resistance resistor model, which is also called pyrolytic carbon film resistors. The main features of the carbon film resistor is relatively good high-frequency characteristics, wide resistance range, cheap, but poor accuracy. China is currently the largest production volume, most widely used general-purpose resistor. It is widely used tape recorders, televisions and other electronic products.
