Note: Electrical characteristics mentioned above are the values at JIS standard condition
(temperature 15 to 35degC, relative humidity 25 to 75%, atmospheric pressure 86k to 106kPa) unless otherwise specified.
Note: Care shall be taken on the heat generated on PC board when maximum carrying current exceeds 10A.
Please perform the confirmation test with actual conditions.
*
¹: Minimum switching loads mentioned above are reference values. Please perform the confirmation test with actual load before production
since reference values may vary according to switching frequencies, environmental conditions and expected reliability levels.
*
²
Electrical life at resistive load mentioned above are the values when a varistor is used as coil suppresion device.
Using protection device other than varistor, the contact life expectancy may decrease drastically.
