FEATURES
q
Compact for high density packaging.
(60% volume of previous generation FBR512).
q
High contact capacity with proven contact material.
(100,000 operations, 14 V, 25 A achieved, even with reduced size).
q
Coil power savings
(600mW nominal achieved with state-of-the-art magnetic analysis/
design).
q
125C version is available.
q
Ease of PCB layout
(all terminals on perimeter, coil and contact terminals separated).
q
Pin compatible with low acoustic noise relay, FTR-P2.
q
Optional over-voltage circuit breaking capability
(0.6mm gap, contact our representative).
q
Packaging for auto-insertion
(tube packing, 30 relays/tube).
