Coil Ratings

MY(S)

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23

°C with tolerances of +15%/–20% for rated currents and ±15% for DC coil

resistance.

2. Performance characteristic data are measured at a coil temperature of 23

°C.

3. AC coil resistance and impedance are provided as reference values (at 60 Hz).

4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder resistor if required.

MY2ZN, MY

@F, MY4(Z)H

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/

−20% for the AC rated current and ±15% for the

DC coil resistance.

2. The AC coil resistance and inductance values are reference values only (at 60 Hz).

3. Operating characteristics were measured at a coil temperature of 23°C.

4. The maximum voltage capacity was measured at an ambient temperature of 23°C.

*1. There is variation between products, but actual values are 80% max.

To ensure operation, apply at least 80% of the rated value

*2. There is variation between products, but actual values are 30% minimum for AC and 10% minimum for DC. To ensure release, use a value that is lower than the

specified value.

Note: Refer to page 19 for the coil specifications of the MY2K.
