    Tech-Etch Inc - TF250M42C070-16-15 - Beryllium-Copper Fingerstock Gasket, EMI RFI Shielding Strips.

    Shielding strips are required by a wide range of industries for a variety of applications. EMI/RFI Shielding Products are designed to either keep out or keep in electromagnetic interference. Shielding reflects and absorbs incident radiation. The higher the attenuation of the shielding, the more effective it is at keeping in or out the undesired electromagnetic interference.

    Beryllium Copper (BeCu) is a high performance metal which can be fabricated into a wide variety of components. Its mechanical and electrical properties make it the ideal material for EMI/RFI shielding products.

    Beryllium Copper EMI Shielding performance

    • High electrical and RF conductivity
    • Superior tensile strength & attenuation
    • RoHS compliant & recyclable
    • Excellent corrosion resistance
    • Excellent plating compatibility
    • Maximum spring properties
    • Moisture and UV resistant
    • Superior endurance over other alloys

    Clip-on Mounting provides a reliable mechanical installation when there is an accessible mounting flange.

    Lambda - L-20-OV-20 - Overvoltage Protector.

    The L-20-OV Series of Overvoltage Protectors are hybrid devices designed to prevent damage to a load caused by excessive power supply output voltage. Load protection is accomplished by effectively short circuiting the output terminals of the power supply when the trip point is exceeded. The L-20-OV is reset when s power to the overvoltage protector is interrupted and its case temperature has fallen below 71°C. An external heatsink is required to maintain case temperature below rated limit.

    The L-20-OV Series is available for nominal supply voltages from 5 to 30 volts. The trip point voltage is fixed and cannot be adjusted. This two terminal device is available in a hybrid with an isolated flange.

    20V, Trip 22.8V +/- 0.7V

    On State Current; 20 A

    On State Voltage: 1.75V
