CQ 1 FORM C AUTOMOTIVE SILENT RELAY
CQ RELAYS (ACQ)
FEATURES
TYPICAL APPLICATIONS
• Sound pressure reduced by approx. 20 dB from that of the company’s non-silent relays • Space saving • Adopting standard terminal pitch (for compact relays) • Plastic sealed type • Wiper load models are listed
For intermittent wipers and applications requiring quiet operation

Notes: *1.This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load. *2.The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to “6. Usage, Storage and Transport Conditions“ in AMBIENT ENVIRONMENT section in Relay Technical Information. *3.Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions. *4.Motor load does not apply to wiper load applications.
