RXLG series aluminum shell wire-wound resistors adopt aluminum alloy shell and have beautiful appearance. This kind of resistor has weather resistance, vibration resistance, and is safer than traditional porcelain skeleton resistor. RXLG resistor is a power wire-wound resistor encapsulated with a high temperature resistant silicone resin and silicon powder as basic materials. It is easy to install tightly and easy to attach a heat sink.
