Signal relay meets Telcordia lightning standards

10 March 2004 Switches, Relays & Keypads

Fujitsu Components' FTR-C1 is a 1 A relay that meets Telcordia's second lightning surge requirement of 5000 V between coil and contacts, as well as the 2500 V lightning surge between open contacts.

The relay also meets the IEEE802.3 standard for 1500 V a.c. breakdown voltage (1 minute) between open contacts.

Available in 3, 4,5, 5, 12 and 24 V d.c. C coils, the FTR-C1 relay features 2,0 mm clearance and 2,5 mm creepage distance between coil and contacts, which meets the 250 V IEC60950 working voltage supplementary insulation requirement. Applications include xDSL, digital loop carrier, access networking, voice over IP, modems, and fax machines.

The FTR-C1 comes in standard and single coil latching versions, with either SMT or through-hole bifurcated contacts. The 2 Form C relay measures 15 x 7,5 mm and height is 9,3 mm (through-hole), 9,65 mm (SMT).
