 6 / 8 page HOW TO USE MULTIPLE WINDINGSLTOTAL = LBASE x S2= 10 µH x 22= 40 µHWhere:LBASE = Inductance of a single windingP = Number of windings in parallel (use 1 with all windings in series)S = Number of windings in seriesIBASE = Maximum current rating of one windingIMAX= IBASE x P= 1 Amp x 1= 1 AmpLTOTAL = LBASE x S2= 10 µH x 12= 10 µHIMAX= IBASE x P= 1 Amp x 2= 2 Amps10µH1 Amp10µH1 Amp10µH1 AmpSeries Connected (2 Windings)Parallel Connected (2 Windings)10µH1 AmpDiscrete inductors combine like resistors, when connected in series or parallel. For example, inductors in series add andinductors in parallel reduce in a way similar to Ohm’s Law.Windings on the same magnetic core behave differently. Two windings in series result in four times the inductance of asingle winding. This is because the inductance varies proportionately to the square of the turns.ParalleledVERSA-PAC windings result in no change to the net inductance because the total number of turns remainsunchanged; only the effective wire size becomes larger. Two parallel windings result in approximately twice the currentcarrying capability of a single winding. The net inductance of a givenPCM configuration is based on the number ofwindings in series squared multiplied by the inductance of a single winding (LBASE). The current rating of aPCM configurationis derived by multiplying the maximum current rating of one winding (IBASE) by the number of windings in parallel. Examplesof simple two-winding devices are shown below:LSeries = L1 + L2 + L3...LnLParallel = 1/ [1/ L1 + 1/ L2 + 1/ L3....1/Ln]®VERSA-PAC®Inductors and Transformers(Surface Mount)
