CQ 1 FORM C AUTOMOTIVE SILENT RELAY
CQ RELAYS
FEATURES 17.0 .669
• Silent Noise has been reduced by approximately 20 dB, using our own silencing design. • Less space required Measuring only 17(L)×13(W)mm (.669(L)×.512(W) inches), this product ranks first among automotive quiet relays in terms of saving space. • Sealed construction
13.0 .512 16.6 .654
