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.
