SF Relay Slim type

Coil data

Operating characteristics such as "Operate voltage" and "Release voltage" are influenced by mounting conditions or ambient temperature, etc.
Therefore, please use the relay within ±5% of rated coil voltage.

"Initial" means the condition of products at the time of delivery.

*1This value is a rough indication of the lower limit at which switching is possible at micro load level.
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.
*2Response time is the time after the coil voltage turns off until the time when form A contact turns off.
*3The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value.
Refer to "7.Usage, transport and storage conditions" in SF Relays Cautions For Use.
*4Response time of with diode type is Max. 12 ms (without bounce when rated coil voltage is applied).
*5When the temperature is 70 to 85°C, reduce the max. continuous carrying current by 0.1 A/°C.
