CMF5589K800BHEA

CMF5589K800BHEA application field and working principle

Through-hole resistors are mainly used for current limiting and impedance matching in industrial equipment. The CMF5589K800BHEA is a kind of the through-hole resistors. It is a metal film resistor with an adjustable resistance value. The maximum operating power of the resistor is 2.5W and the maximum insulation resistance is 1000 MΩ.

Design structure

CMF5589K800BHEA is made of high-quality ceramic particles and stainless steel parts. The ceramic particles are made of high-quality components and guarantee long-term insulation stability. It is shaped into a cylindrical structure, with a diameter of 8.1mm and a total height of 12.7mm. The steel housing has a special structure. It is made of high-temperature alloy strip. Inside the steel housing, there is screw leading out or in with a 3mm gap.

Working principle

CMF5589K800BHEA is composed of power resistor, terminals and adjustment parts. When voltage is applied, current generates Joule heat in the power resistor, passing through the connecting wire, and then out of the lead-out terminal; when adjusting the adjustment part, the movable contact moves to increase or decrease the contact resistance and finally to obtain the accurate output current. The voltage drop across the resistor arms is proportional to the current through the arms. This relationship is described by Ohm\'s law.

Applications

CMF5589K800BHEA is mainly used in reliable and accurate power control, circuit gain control, overload protection, current measurement, and share load for distribution systems. It has high stability, low noise, high-temperature performance, no spark phenomenon and strong surge suppression ability, making it suitable for the most stringent industrial application environment. It is widely used in all kinds of precision instruments, communications, electrical appliances, aerospace, automation equipment and so on.
