2. Specifications
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. (AgPd contact type is available for low level load switching [10V DC, 10mA max. level])
*2 Refer to “AMBIENT ENVIRONMENT” in GENERAL APPLICATION GUIDELINES.
