Coilcraft, Inc. PL140 Series SMT Planar Transformers PL140-106L

The PL140-106L is a surface mount planar transformer rated for 140 Watts, designed for operation between 200 kHz and 500 kHz with a nominal −48 V input. It features a 9:1 turns ratio, 152 µH primary inductance, 0.35 µH maximum leakage inductance, 32.8 mΩ primary DCR, and 0.5 mΩ secondary DCR. It uses schematic D, with dual secondary outputs of 0.5 mΩ each across pins 6-7 and 9-10. The component has 1500 Vdc primary-to-secondary isolation, operates from −40°C to +85°C ambient, and reaches a maximum part temperature of +125°C. It is housed in a surface mount package with matte tin over nickel over brass terminations, weighs 10.9-12 g, and meets MSL 1 moisture sensitivity. Packaging is 200 parts per 13-inch reel on 44 mm wide embossed plastic tape. No auxiliary winding is present.
