Wire-wound resistor LF2 series

powerboard-mount

RCD type LF2 is designed to provide circuit protection for telecom applications, such as line feed, ADSL, HDSL, and switching networks, as well as snubber circuits, switching regulators, power faults, etc. The LF2 is a combination power resistor and isolated thermal fuse housed in a ceramic case. The combination enables the device to withstand short-time overloads (various lightning surges, AC power crosses, inrush currents, and ESD pulses), yet open safely under extended overload conditions. The all-welded internal construction combined with highest grade materials ensures utmost performance and reliability. For even greater protection under power cross conditions, as required by TR1089, specify LF2A.
