and
r15%
for DC coil resistance.
2. Performance characteristic data are measured at a coil temperatures of 23qC.
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.

Approved by Standards
Some MY Relays are available in models meeting various safety
standards. When ordering, you must specify the desired standards.
Refer to
Ordering Information
for specific models. Note that the rat-
ing recognized by the various standards sometimes vary from the
ratings of the individual relays.
