Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-rohs tin-lead (63/37). Packaging: All but HP6 and HPH6: D = 3 machine-ready reel. EIA-48 embossed plastic tape B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($5 charge), use code letter D instead. HP6 and HPH6: 4 per tray (no code). Inductance is per winding, measured at 00 khz, 0. Vrms, 0 Adc. 3. DCR is per winding, measured on Cambridge Technology micro-oheter or equivalent. 4. Volt-time product is for a single winding or multiple windings connected in parallel. To calculate volttime product for windings connected in series, multiply the value specified in the table by the number of windings connected in series. 5. Peak energy storage is for any combination of windings, assuming saturation current applied. See note 6 for definition of saturation current. 6. 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. 7. Current that causes a 40 C rise from 5 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. 8. Part is designed exclusively for use as a forward converter transformer and was not tested for energy storage and saturation current. 9. Electrical specifications at 5 C.
