PL18 series planar transformers for forward topology, rated to 100 W with an 18–36 or 36–75 Vdc input. A 18.3 × 19.2 mm footprint at 6.5 mm maximum height, with 1750 Vdc basic isolation — the mid-size member of the PL family between PL14 and PL58 AC.
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.
