Thermal Curve
Important Notice
1. Soldering must be finished within 10 seconds at 260˚C,or finished within 5 seconds at 350˚C. Otherwise it may
cause damage to the relay.
2. Terminal polarity must be observed. Otherwise it may cause damage to the relay.
3. When ambient temperature is above 25˚C, the maximum load current decreases. See thermal derating curve.
