Product name: RXLG-H-F Series Wire wound resistors in aluminum casing
Type: RXLG-H-F
Product introduction: RXLG series wire wound resistor in aluminum casing is made by aluminum casing and has a handsome appearance. Its ability of resistance to vibration, climate and security is precede to those resistors with ceramic framework. This resistor is power wire wound resistor which is made by a kind of organic silicon rosin and silicon powder as basic material encapsulation. It is easy to fix tightly and add to radiator.
Purpose: Wire wound resistors in aluminum casing is used in electric loop of power supply, transducer, servo system and so on widely. It can also be used in wicked industry control environment. It is a ideal product of electric.
