LPR6235 Series

Coupled Inductors for Step-Up & Flyback Applications

RoHS-konform Halogenfrei
This is a new halogen free version recommended for new designs. Only the termination material and part number have changed. The previous version is available only to current customers.
Coilcraft LPR6235 Series low-profile 1:N coupled power inductors are ideal for a variety of voltage step-up and step-down applications, including low voltage step-up in energy harvesting designs. They offer excellent coupling coefficient (K > 0.95) and 200 Vrms, one-minute isolation (hipot) between windings.
  • Different turns ratios for a variety of voltage step-up and step-down applications.
  • Perfect for low voltage step-up in energy harvesting applications
  • Selected by Linear Technology for their LTC3108 and LTC3109 Ultralow Voltage Step-Up Converter and Power Managers
  • Excellent coupling coefficient: K > 0.95
300 Vrms, one minute isolation (hipot) betweeen windings

Hinweise
  1. When ordering, please specify termination and packaging codes: e.g. LPR6235-253PMRC
  2. Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. SRF measured using an Agilent/HP 4191A or equivalent.
  5. Isat: DC current applied to L1 at which the inductance drops 10% from its value without current.
