2510 & 2520 Data & Signal SPDs

Bourns 2510 and 2520 Data and Signal Surge Protective Devices (SPD) are designed to protect 1-pair and 2-pair data lines with common reference potential in data, signal, and communications systems from electrical surges. The SPDs feature a 20kA max discharge current rating and a 100MHz cut-off frequency rating. The SPDs offer a non-interruptible signal transmission during module exchange and pluggable surge protection for DIN-rail mounting. Bourns 2510 and 2520 Data and Signal SPDs are IEC 61643-21 compliant and ideal for telecommunications, low-voltage alarm circuits, high-frequency transmission systems, analog/digital communications, and RS-232, RS-422, and RS-485 interface applications.
