Document 613-1 Hexa-Path Magnetics HP3, HPH3 * Six 1 : 1 isolated windings that can be connected in series or parallel * Tightly coupled windings * 500 Vrms, one minute isolation between each winding * Power range: 5 - 50 Watts as inductor and flyback transformer; up to 150 Watts as forward transformer * Frequency range up to 1 MHz These off-the shelf parts can be used to create thousands of configurations, providing a convenient method for designers to create custom magnetics. By connecting the windings in series or parallel, the Hexa-Path components can be configured as inductors, coupled inductors and transformers for use in virtually any application: flyback, buck/boost, push-pull, forward, full and half bridge, Cuk, and SEPIC. There are six different sizes available with five HP parts and five HPH parts in each size. The HP offers lower DCR and higher Irms ratings. The HPH offers higher inductance and greater energy storage capabilities.

EIA-481 embossed plastic tape B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. HP6 and HPH6: 24 per tray (no code) 2. Inductance is per winding, measured at 100 kHz, 0.1 Vrms, 0 Adc. 3. DCR is per winding, measured on Cambridge Technology micro-ohmmeter 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 = Isattable x 6 / number of windings in series. 7. Current that causes a 40C rise from 25C 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 25C.
