    Noninductive Metal Plate Cement Resistor Noninductive MPR Serie Ceramic Composition 2 Watt  2.2ohm 2.2E Resistance Value

    Product Description:

    cement resistors are made by cut trimming metal oxide film core or winding resistance wires around non-alkaline ceramic core, either is added with a layer of heat and humidity resistant and non-corrosive protective material. The wire wound resistor or metal oxide resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement.
