Note: All values above are measured in early time under an ambient temperature of +20°CC and humidity of 65% unless stated.
*1. This is an acceptable current-carrying value in abnormal, and this is not a value which guarantee a repeat current-carrying.
Please check under actual use condition before use.
*2. Measured with a voltage drop method at DC6V 1A.
*3. It changes depend on how the rated voltage is operated, but bounce-time is not included.
*4. Measured at DC500V.
*5. Measured under 1mA of leak current, 50/60Hz for 1minute.
*6. Minimum Order Quantity is subject to change, please feel free to contact our sales representatives.
