NOTES
SERIES YC
[1] Standard Intermediate current test applicable. Relay can also switch low level load while switching any of the
other rated loads on adjacent contacts.
[2] Inductive load life, 10,000 cycles.
[3] Low level endurance test: contact load of 10 to 50 millivolt, 10 to 50 microamp, 100 Ohm max. contact
resistance.
[4] Refer to MIL-PRF-6106 for details.
[5] "N," "R," & "V" coil have back EMF suppression to 42 volts maximum.
[6] 500 Vrms with silicone gasket compressed, all other conditions 250 Vrms coil to case, 350 Vrms all other
points.
[7] Applicable to Type "N," "R" & "V" coils.
8. Reference MIL-PRF-6106.
9. Relay will not operate, but will not be damaged by application of reverse polarity to coil.
