Product Description
Cosmo KPC357NT Series 4PIN MINI-FLAT PHOTOTRANSISTOR PHOTOCOUPLER
The KPC357NT is a DC-input, single-channel photocoupler featuring a light-emitting diode optically coupled to a phototransistor. Housed in a compact 4-pin Mini-Flat package with a 2.0mm profile, it offers high density mounting suitability. This device provides an input-output isolation voltage of 3750 Vrms and is Pb-free and RoHS compliant. It is ideal for applications such as hybrid substrates, programmable controllers, DC-DC converters, and telecommunication equipment.
