    300 Watt Wire-wound Aluminum Braking Resistors Metal Case DIP Installation 10R 20R 30 ohm Suitable for Power Supply

    Construction of High Power Braking Aluminum Case Resistors

    1.An aluminum encased consists of an alloy metal coil-type resistance element assembled into an aluminum enclosure.
    2.Following high-temperature anodization, the enclosure is filled with a specialnon-flammable cement paste and after hardening. Insulation is applied through a high temperature process.
    3.Since this component is embedded in the heat-proof cement, it is not affected by external mechanical force, and dusty environments.
