POE300F series transformers operate over a temperature range from -40 to +125°C, feature 1500V rms primary-to-secondary isolation and 500V rms primary-to-auxiliary isolation.
The terminations are RoHS compliant tin-silver over tin over nickel over phos bronze (others are available on request). It offers high resistance to soldering heat, withstanding a maximum of three 40s reflows at +260°C.
Coilcraft also offers a Designer’s Kit (C398) that contains three samples of each of the series’ five values.
