    10W 33ohm SQP  Precision Cement Resistors Flammeproof Non-inductive Wire-wound Ceramic Case Suitable for Printed Circuit Board


    Construction of SQP type cement resistors:


    7W SQP Construction.png


    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


    Material Specifications (SQ)

    Core :High purity grade alumina ceramic rod.

    Terminals :Tin/lead plated (Lead (Pb)-free will be 100 % tin).

    Body : Steatite ceramic case with inorganic potting compound.

    Element :Copper-nickel alloy, nickel-chrome alloy, resistive wirewound or power film depending on resistance value.


    Features

    1. Precision resistance values with longer life.

    2. In high resistance values,the winding cores will be replaced by power film cores.

    3. Super heat dissipation;small linear temperature coefficient.

    4.Small dimension,excellent stability in high temperature,resistant to humidity and shock.

    5. Completely insulated character suitable for printed circuit board.

    6. Instant overload capability; low noise figures and low annual shift on resistance values.


    Applications :

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