HF flat coil SMT transformers handle up to 500 W

The PH08 and PH09 series of low-loss, flat coil surface mount planar transformers handle up to 500 W and come 21.6 x 23.4 x 8.6 mm or 26.7 x 29.5 x 11.9 mm packages, respectively. The transformers operate from 200 to 700 kHz. Primary winding resistance is reduced by 50% over previous versions.

The transformers low leakage inductance cuts high voltage spikes and snubber circuit losses. Primary to secondary isolation is 1,000 or 1,750 Vdc. They have single turn dual, triple, or quad secondaries and, 8 to 16 turn tapped primaries. $3.00 to $4.50 in quantities of 50,000 pieces.
