April 1997 PBR 5111/2 LPC Line Resistor Network Description Key Features • Two matched resistors in a single- The Line Protection Resistor Network (LPC) PBR 5111/2 consists of a ratio matched in-line package pair of thickfilm resistors on a ceramic substrate. PBR 5111/2 is used in telephone line interface overvoltage protection networks, where the LPC resistors limit the • Ratio match maintained after current flow through voltage clamping devices such as diodes, tranzorbs, silicon multiple surges thyristor diode transient suppressors etc. • Ratio match maintained after The resistors will withstand multiple voltage/current surges of either polarity without multiple non destructive power cross failure and with only a negligible change inside specified values.If exposed to • Fu
