Product Description
Sliding resistor Ceramic Variable Resistor
1.BC1 High power wirewound sliding rheostat are wound with chromium-alloy wire as a resistor element.
2.The entire component is coated non-flammable and high-temperature resin exception for the
slide contact surface.
3.After cooling and drying, insulation is applied through a high-temperature process. Installed
centered roating adjuster component slides along the resistance element to vary the
to the desired value.
4.High power rating,resistance to humidity, resistance value in great adjustable range.
5.On one resistor ,can have the different resistance requirement(flat and round wire can be in the same rheostat).
