Note: 1. Design Guarantee. (Outgoing inspection is not done on all products.)

2. This product is not designed for protection against radioactive rays.

3. All characteristic are measured with a capacity across the input (0.33µF) and the output (22µF).

T

(except for temperature coefficient of output voltage)caused by temperature change are not considered.
