■Ratings
●Coil
Note 1. The rated current and coil resistance are measured at a coil
temperature of 23°C with a tolerance of ±15%.
2.The operating characteristics are measured at a coil temperature of
23°C.
3.The “Max. voltage” is the maximum voltage that can be applied to the
relay coil.
●Contacts
■Characteristics
Note: The above values are initial values.
*1. The contact resistance was measured with 1 A at 5 VDC with a
fall-of-potential method.
*2. The insulation resistance was measured with a 500 VDC Megger Tester
applied to the same parts as those for checking the dielectric strength.
*3. This value was measured at a switching frequency of 120 operations/min.

■ Precautions
●Please refer to “PCB Relays Common Precautions” for correct use.
●Mounting
• When mounting more than two Relays
on a PCB, keep the gap as shown in
the following figure.
• No specified mounting direction.
• Not compatible with sockets.
• There is the current-carrying metal
part on the coil terminal.
Do not mount to the PCB with
patterned metal surface.
●Other Precautions
• This Relay is suitable for power load
switching of motors, transformers,
solenoids, lamps, heaters, etc. Do not
use the G4W to switch micro loads
less than 100 mA, such as in signal
applications.
