FEATURES
q
Low operating sound
An original silent mechanism decreases the propagation of operat-
ing sound when mounted on a PCB. (Average sound pressure:
50dB at 5 cm).
q
Compact, high density package
350 mm
2
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
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 sup-
plied.
q
Typical applications
Power window, Doorlock, Power seat, Wiper (for H-Bridge circuit)

*This is the standard value of the minimum load level. This value may differ depending on the switching frequency,
environmental conditions and target reliability standard. We recommend to check this value by an actual load prior to use.
