SILENT TWIN RELAY FOR AUTOMOTIVE APPLICATIONS 1POLE X 2, H-BRIDGE, 25A
FTR-P2 SERIES
s FEATURES
q Low operating sound An original silent mechanism decreases the propagation of operating sound when mounted on a PCB. (Average sound pressure:
50dB at 5 cm). q Compact, high density package
350 mm2 mounting area. (11% less than the FBR 510 series non-
quiet twin relay).
q High sensitivity, low power consumption
(nominal power consumption: 450 mW). q High capacity
DataSheet4U.com
Heat dissipation is high due to a single cover structure.
q Ease of PCB layout
The FTR-P2 incorporates internal H-Bridge connections typically used in reversing applications. All terminals are on the perimeter. q High breaking capability.
In addition to the standard gap product (0.3 mm), a higher gap product (0.6 mm), suitable for over voltage breaking can be supplied.
q Typical applications Power window, Doorlock, Power seat, Wiper (for H-Bridge circuit)
