PL300 Series

SMT Planar Transformers

RoHS compliant AEC-Q flag
  • Rated for 300 Watts between 200 kHz and 700 kHz with a nominal 48 V input.
  • High efficiency; excellent DCR; very low leakage inductance
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • 1500 Vrms, one minute primary to secondary isolation.
  • Provides 0.009 inch (0.229 mm) clearance above the seating plane
  • Can be special ordered with an optional auxiliary winding
  • The smaller PL160 Series is rated at 160 Watts
  • RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations
  • Two samples of each PL300 and PL160 parts are available in Coilcraft Designer's Kit C460

Notes
  1. To order a transformer with an optional auxiliary winding, add an “X” and the turn count after the PL300, e.g. PL300X3-100LB.
    Turn counts of 1, 2, 3, 4, 5, 7 and 9 are available for the auxiliary winding.
    Transformers with auxiliary windings are not stocked. Call for lead time.
  2. Inductance measured on an Agilent/HP 4284 at 200 kHz, 0.5 Vrms, 0 Adc between pins 2 and 5 with pins 3 and 4 connected.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. DCR for secondary is measured between pins 7 and 11.
  4. Leakage inductance measured at 200 kHz, 0.5 Vrms, 0 Adc between pins 2 and 5, with pins 3 and 4 connected, and with all secondary pins shorted
  5. Volt-time product is based on primary windings connected in series.
