Notes:

This value can change due to the switching frequency, environmental conditions, and desired reliability level, it is recommended to check this with the actual load
Coil holding voltage is the coil voltage after 100ms from the applied nominal voltage.
According to EN 61810-1:2015, table 2.
Important: Relay characteristics may be influenced by:
- strong external magnetic fields
- magnetic conductive materials near the relay
- narrow top-to-top mounting (printed surface to printed surface)

NOTES

Coil operating power
Pure DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different.
Coil connection
When connecting coils, refer to the wiring diagram to prevent mis- operation or malfunction.
Soldering
When using automatic soldering, the following conditions are recommended
Preheating: 120°C 248°F, within 120 sec (PC board solder surface)
Soldering: 260°C±5°C
500°F±41°F, within 6 sec
