RATING

1. Coil data

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.

*3. Please inquire if you will be using the relay in a high temperature atmosphere.
