PFD2015 Series

Coupled Power Inductors

Coilcraft PFD2015 Series of miniature 1:1 coupled power inductors are used as low-power isolation transformers in SEPIC applications, or as common mode chokes. A wide range of inductance values means a large selection of bandwidths, all with low insertion loss.

Smallest coupled shielded power inductor – 2.2 × 1.45 mm footprint, 1.5 mm high
Excellent as low-power isolation transformers
Great for Flyback, SEPIC, Ćuk, Zeta and other applications
Magnetically shielded for compact size and minimized EM

注释

When ordering, please specify packaging code: e.g. PFD2015-103MEC
Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
For SEPIC: When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value.
DCR is for each winding. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
For SEPIC: When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
For SEPIC: SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
Leakage inductance is for L1 and is measured with L2 shorted.
For SEPIC: DC current, at which the inductance drops the specified amount from its value without current. It is the sum of the current flowing in both windings.
For SEPIC: Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. Determine temperature rise.
For SEPIC: Irms, one winding: Maximum current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.
