2. Speciﬁcations

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.
