Notes

When ordering, please specify packaging code: e.g. HPH1-1400LD
Inductance is per winding, measured at 100 kHz, 0.1 Vrms, 0 Adc.
DCR is per winding, measured at 25°C on Cambridge Technology micro-ohmmeter or equivalent. For other operating temperatures,use this DCR at Temperature calculator.
Volt-time product is for a single winding or multiple windings connected in parallel. To calculate volt-time product for windings connected in series, multiply the value specified in the table by the number of windings connected.
Peak energy storage is for any combination of windings, assuming saturation current applied. See note 6 for definition of saturation current.
Isat: DC current at which the inductance drops 30% typ from its value without current, based on current applied to all six windings connected in series. For applications where all windings are not connected in series, use the following equation to calculate Isat: Isat = Isat(table) × 6 ÷ number of windings in series.
Irms: Current that causes a 40°C rise from 25°C ambient due to self heating, tested with continuous current flow through all windings connected in series. Application temperature rise will depend on the operating current, duty cycle, and winding connection.
Part is designed exclusively for use as a forward converter transformer and was not tested for energy storage and saturation current.

Termination:

L = RoHS compliant tin-silver over tin over nickel over phos bronze.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
