FEATURES
• Compact flat type
Flat size enables it to be built-in switch
units.
<Height>
PC board terminal type:
9.5 mm .374 inch
Surface-mount terminal type:
10.5mm .413inch
• High capacity
CP Relay provides low profile
spacesaving advantages while offering
high continuous current of 25A (1 hour).
• Simple footprint pattern enables
ease of PC board layout
Arrangement of coil and contact
terminals designed to withstand large
capacity which ensures leeway and
facilitates PC board design.
• Sealed construction
Sealed construction suitable for harsh
environments
• “PC board terminal” and “Surface
mount terminal” types available
SMD automatic mounting is possible for
surface mount terminal types because
tape and reel packaging is used.
• Model available for wiper load.
TYPICAL APPLICATIONS
For automotive system
Power windows, Auto door lock, Power
sunroof, Memory seat, Wiper, Defogger,
Blower fan, EPS, ABS etc.

RATING
1. Coil data
Note: Other pick-up voltage types are also available. Please contact us for details.
2. Specifications
1) Standard CP relay
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. Please refer to “Usage ambient
condition” in CAUTIONS FOR USE OF AUTOMOTIVE RELAYS.
Please inquire if you will be using the relay in a high temperature atmosphere (110°C 230°F).
*3. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
2) For wiper load
Anything outside of that given below complies with standard CP relays.
Note: *1. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
