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
