    SQZ High Power Wire-wound Cement Resistors 3W 10ohm Wide Resistance Range Variable Load Life in Electrical Equipment


    Product Description:

    Cement resistors are made by winding the resistance wires on the alkaliless ceramic cores,then coated with noncorrosive, heat-proof and humidity-proof material. Cement type is the one with special flameproof cement stuffed in the ceramic case.


    Construction:

    SQZ type cement resistors construction.png

    Ceramic core : High alumina ceramic is used.

    Resistor element :The resistor element shall consist of metal oxide film or Resistance wire

    Terminal : Tinned iron cap.

    Connection : The lead wire,which is plated with solder,shall be mounted to the caps by welding process.

    Lead wire:Soldered or tinned annealed wire.

    Silicon cement : Silicon resin is used. Accord with UL-94V-0 Nonflammable specification

    Ceramic case : High thermal conductivity


    Features

    1, shock, moisture, heat and good heat, low prices and other characteristics.

    2, completely insulated, suitable for printed circuit boards.

    3, porcelain rod winding and then welded joints, the system made a precise resistance and extend the life.

    4, high resistance value using metal oxide film (MO) instead of winding way.

    5, excellent heat resistance, resistance temperature coefficient is small, a linear change.

    6, resistance to short time overload, low noise, resistance has not changed year after year.

    7. Explosion-proof performance, and play a protective role



    Applications :

    Power supplies/Voltage dividers/Motor controllers/Automotive applications/Power electronics circuits
