All values above are measured in early time under an ambient temperature of +20°C and humidity of 65% unless stated.
The value stated is at maximum temperature in a guaranteed ambient temperature.
It changes depend on how the rated voltage is operated, but bounce-time is not included.
Measured at DC500V.
Measured under 1mA of leak current, 50/60Hz for 1minute.
Minimum Order Quantity is subject to change, please feel free to contact our sales representatives.
