- Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load. 

   - *2. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage conditions in NOTES. 

   - *3. According to EN 61810-1:2010, table 2. Characteristic is sealed construction with terminals, case and base sealed shut with sealing resin. Construction is designed to prevent seeping of flux when soldering and cleaning fluid when cleaning. Harmful substances on the contacts are removed by gas purging before sealing with. 

   - *4. Coil holding voltage is the coil voltage after 100 ms from the applied nominal voltage. 

## **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** 

## **1. For cautions for use, please read “General Application Guidelines” on page B-1.** 

## **2. 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. 

## **3. Coil connection** 

When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 

## **4. Soldering** 

When using automatic soldering, the following conditions are recommended 

1) Preheating: 120°C 248°F, within 120 sec (PC board solder surface) 2) Soldering: 260°C±5°C 500°F±41°F, within 6 sec
