SUPER MINIATURE
PC BOARD TYPE
AUTOMOTIVE RELAY
RoHS compliant
CJ RELAYS (ACJ)
FEATURES
TYPICAL APPLICATIONS
• Smallest in its class, it is extremely
compact at approx. 2/3 the size of
previous products.
Compared to our previous miniature type
CT relay, both the 1 Form C and 10-pin
and 8-pin twin types take up approx. twothirds the space and volume. This makes
them ideal for relay unit miniaturization.
• Compact and high-capacity 25 A load
switching
High capacity control is possible while
being compact and capable of motor lock
load switching at 25 A, 14 V DC.
• Pin in Paste* compatible model
added
Models compatible with the recently
increasing Pin in Paste technique (reflow
solder mounting) have been added.
Pin in Paste compatible models are the
flux tight type.
* The Pin in Paste method may
sometimes be referred to as THR
(Through-hole Reflow).
• Environmental protection
specifications
Cadmium-free contacts and use of leadfree solder are standard. Environmental
pollutants are not used.
• Powered windows
• Automatic door locks
• Electrically powered mirrors
• Powered sunroofs
• Powered seats
• Lift gates
• Smart J/B related products, 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.
* If the relay is used continuously for long periods of time with coils on both sides in an energized condition, breakdown might occur due to abnormal heating
depending on the carrying condition. Therefore, please inquire when using with a circuit that causes an energized condition on both sides simultaneously.
