VP Technical Data 4301 Effective August 2017 VERSA-PAC® Inductors and Transformers (Surface Mount) How to use multiple windings Discrete inductors combine like resistors, when connected in series or parallel. For example, inductors in series add and inductors in parallel reduce in a way similar to Ohm’s Law. L = L1 + L2 + L3...Ln Series L = 1/[1/L1 + 1/L2 + 1/L3....1/Ln] Parallel Windings on the same magnetic core behave differently.Two windings in series result in four times the inductance of a single winding. This is because the inductance varies proportionately to the square of the turns. Paralleled VERSA-PAC windings result in no change to the net inductance because the total number of turns remains unchanged;only the effective wire size becomes larger. Two parallel windings result in approximately twice the current carrying capability of a single winding.The net inductance of a given PCM configuration is based on the number of windings in series squared multiplied by the inductance of a single winding (L ).The current rating of a PCMconfiguration BASE is derived by multiplying the maximum current rating of one winding (I )by the number of windings in parallel. Examples BASE ofsimple two-winding devices are shown below: Series Connected (2 Windings) Parallel Connected (2Windings) 10µH 1Amp 10µH 10µH 1Amp 1Amp 10µH 1Amp L = L x S2 I = I x P L = L x S2 I = I x P TOTAL BASE MAX BASE TOTAL BASE MAX BASE = 10 µH x 22 = 1 Amp x 1 = 10 µH x 12 = 1 Amp x 2 = 40 µH = 1 Amp = 10 µH = 2 Amps Where: L = Inductance of a single winding BASE P = Number of windings in parallel (use 1 with all windings in series) S = Number of windings in series I = Maximum current rating of one winding BASE 6 www.eaton.com/electronics

VP Technical Data 4301 VERSA-PAC® Inductors and Transformers (Surface Mount) Effective August 2017 How to pin-configure VERSA-PAC® Each VERSA-PAC can be configured in a variety of ways by simply connecting pins together on the Printed Circuit Board (PCB). As shown below, the connections on the PCB are equal to the pin configuration statement shown at the bottom of the schematic symbol. Connecting a number of windings in parallel will increase the current carrying capability, while connecting in series will multiply the inductance. Each VERSA-PAC part can be configured in at least 6 combinations for inductor use or configured in at least 15 turns ratios for transformer applications. The VERSA-PAC allows for at least 500 magnetic configurations. The PCM configurations can either be created by the designer or simply chosen from the existign PCM diagrams. The following inductor example shows 6 windings in series, which result in an inductance of 36 times the base inductance and 1 times the base current.

More than 375 transformer combinations may be achieved using the available VERSA-PAC parts.

The printed circuit board layout in each example illustrates the connections to obtain the desired inductance or turns ratio. The examples may be used by the PCB designer to configure VERSA-PAC as desired. To assist the designer, VERSA-PAC phasing, coupling and thermal issues have been considered in each of the PCM configurations illustrated. Additionally, the inductance and current ratings, as a function of the respective base values are shown in each PCM example. It is important to carefully select the proper VERSA-PAC part in order to minimize the component size without exceeding the RMS current capability or saturating the core. The Product specification table indicates maximum ratings. www.eaton.com/electronics 7
