COMPACT FLAT SIZE
FOR AUTOMOTIVE
CP RELAYS
FEATURES
• Compact flat type
Flat size enables it to be built-in switch
units.
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.
RoHS compliant
• 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,
etc.

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.
*4. Motor load does not apply to wiper load applications.

1) After opening a moisture-prevention
package, use the item as soon as
possible (within 3 days under an
environment of Max. 30°C 86°F, Max.
70% RH).
2) If products are not used within 4 days
after opening a moisture-prevention
package, store them in a humiditycontrolled desiccator or in a storage bag
with silica gel.
T1 = 150 to 180°C 302 to 356°F

• Cautions for mounting operations
Temperature profile indicates the
temperature of the soldered part (*1) of
terminals on the surface of a circuit
board. The exterior temperature of a relay
may be extremely high depending on the
component density on the board or the
heating method of the reflow oven or
circuit board type. Sufficient verification
under actual processing conditions is
required.
2) Avoid cleaning (ultrasonic cleaning,
boiling cleaning, etc.) and coating in
order to prevent negative impacts on
relay characteristics.
For general cautions for use, please refer to the “CAUTIONS FOR USE OF AUTOMOTIVE RELAYS”
