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

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23C 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 23C.
4. The maximum voltage capacity was measured at an ambient temperature of 23C.
*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.
