Product specifications- notes
(1) The first three or four digits in the part number signify the size of the (8) Maximum Energy capability of each winding. This is based on 30% package. The next four digits specify the AL, or nanoHenries per turn saturation of the core: squared. -R indicates RoHS compliant. (2) 1 L Energy = S2 BASE = Nominal Inductance of a single winding. SERIES x x 0.7LBASE x I2SAT(BASE) 2 (3) IBASE is the lessor of ISAT(BASE) and IRMS(BASE). 1 (4) Peak current that will result in 30% saturation of the core. This Energy = P2 PARALLEL x x 0.7L 2 BASE x I2SAT(BASE) current value assumes that equal current flows in all six windings. For applications in which all windings are not simultaneously driven For multiple windings, the energy capability varies as the square of (i.e. flyback, SEPIC, Cuk, etc.), the saturation current per winding the number of windings. For example, six windings (either parallel may be calculated as follows: or series) can store 36 times more energy than one winding. 6 x I I SAT(BASE) SAT = Number of Windings Driven (9) Thermal Resistance is the approximate surface temperature rise (5) RMS Current that results in a surface temperature of approximately per Watt of heat loss under still-air conditions. Heat loss is a 40 °C above ambient. The 40 °C rise occurs when the specified combination of core loss and wire loss. The number assumes the current flows through each of the six windings. underlying PCB copper area equals 150% of the component area. (6) Maximum DC Resistance of each winding. (7) For multiple windings in series, the volt-µsecondTOTAL (µVs) capability (10) These devices are designed for feed-forward applications, where varies as the number of windings in series (S): load current dominates magnitizing current. Volt-µsec = S TOTAL x Volt-µsec(BASE)
