For Active Clamp
120WPoEPlanarTransformers Forward Topology
• Designed for active clamp forward topology
• Operates at 200 kHz, with 36 – 72 Volt input
• High efficiency; excellent DCR; very low leakage inductance
• Isolation:1500 Vrms one minute primary and aux to secondary.
• Provides 0.009″ (0.229 mm) clearance above the seating plane
• Includes a 12-Volt auxiliary winding

1. When ordering, please specify packaging code:
POE1±2PL-±4LD
Packaging: Blank In trays, 36 per tray
D = Optional tape and reel (additional cost), 13″ machine-ready reel. EIA-481 embossed plastic
tape. See tape and reel specifications on page 2.
B = Optional tape and reel (additional cost), less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use code letter D instead.
2. Inductance is for the primary, measured at 200 kHz, 0.5 Vrms, 0 Adc.
3. Leakage inductance is for the primary and is measured with the secondary winding shorted.
4. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
