*1	This 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.
*2	For ambient temperature, please refer to the "GUIDELINES FOR RELAY USAGE".
