奥创电子 东莞船型铝壳电阻100W 机床再生电阻 
Power supply, inverter, servo and high-demand harsh environment,long life. Resistance tolerances are 10%, 5%, 3%, 2%, 1%, 0.5%.High-power models can be assembled as needed. Special resistors canalso be made according to customer requirements, and can becombined into a high-power type or large-power type resistorbox.
Aluminum shell resistor manufacturers square wire woundresistors (winding resistors), commonly known as cement electricalgroup, use nickel, chrome, alloy resistance wires in alkalineheat-resistant porcelain pieces, iron and other resistance,external heat, humidity , no corrosion and protective materials,ceramic packaging again, especially non-flame cement packing. Theiradvantages are resistance accuracy, low noise, good heatdissipation, and high power consumption, mainly used for the powerlevel of the amplifier. The disadvantage is that the resistance isnot large and the cost is high, but it is not suitable for usingthe inductor in the high frequency circuit.
