Frequently asked questions
How is it wired in a small power supply?
The two AC terminals connect to the AC source or transformer secondary. The positive and negative DC terminals connect to a filter capacitor and the load. Verify the voltage rating before use.
Does it need a heatsink at 3 A?
At full current, a heatsink or a generous copper area on the PCB helps keep the temperature within limits. Derate the current if the enclosure is warm, as the rated current depends on temperature.
