■Ratings

●Coil

Note 1. The rated current and coil resistance are

measured at a coil temperature of 23

with a tolerance of ±10%.

2. The inductances shown above are

reference values.

3. Operating characteristics are measured at

a coil temperature of 23

4. Max. permissible voltage refers to the

maximum value in a varying range of

operating power voltage, not a continuous

voltage.
