    White Porcelain Shell Cement  Resistors Two Lead Terminals Through Hole 40 Watt 100ohm 100MR as Voltage Divider


    Product Description:


    1.cement resistors are made by winding resistance wires around non-alkaline ceramic core,which is added with a layer of heat and humidity resistant and non-corrosive protective material.

    2.The wire wound resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement.

    3.For high resistance value,wires are replaced by metal oxide films.


    Construction of SQP type cement resistors:

    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
