Note 1. When ordering, add the rated coil voltage to the model number.
Example: G5NB-1A DC5
Rated coil voltage
However, the notation of the coil voltage on the product case as well as on the packing will be marked as @@VDC.
Note 2. When ordering tape packing, add "-SP" to the model number.
Be sure since "-SP" is not part of the relay model number, it is not marked on the relay case.

QPrecautions
OPlease refer to “PCB Relays Common Precautions” for correct use.
Correct Use
OCoil Voltage Reduction (Holding Voltage) after Relay
Operation
• If the coil voltage is reduced to the holding voltage after Relay
operation, first apply the rated voltage to the coil for at least
100 ms, as shown below.
• A voltage of at least 40% of the rated voltage is required for
the coil holding voltage. Do not allow voltage fluctuations to
cause the coil holding voltage to fall below this level.
