RATING
1. Coil data
2. Specifications
Notes: *1. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
*2. 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.
*3. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. For details, please refer to the
“Automotive Relay Users Guide”.
*4. Please inquire our sales representative if you will be using the relay in a high temperature atmosphere.
