PIN CONFIGURATIONS

(2,12)(3,11)(4,10)(5,9)(6,8)

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 existing 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.

INDUCTOR EXAMPLE

FOR SIZES VP3,VP4 AND VP5

The PCM configurations may be selected from the examples

above or created by the designer. 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.

Each VERSA-PAC may be used in at least 15 transformer applications. More than 375 transformer combinations may be

achieved using the available VERSA-PAC parts.
