PL14 series low-profile planar transformers for forward topology, rated to 30 W with an 18–36 or 36–75 Vdc input. The 14.5 × 16.25 mm footprint and 6.0 mm maximum height suit dense telecom and industrial DC-DC converters; a range of primary, auxiliary and secondary winding combinations is available in the same outline.
Stresses beyond values listed may cause permanent damage. Functional operation beyond any rating is not implied. All values at T<sub>amb</sub> = 25 °C unless noted.
