The PQ core was developed for use in power applications. The large core surface area for the
volume of the core aids in heat dissipation.
These cores are employed both in filter and transformer designs in switched-mode power sup-
plies.
• Part number is for a single core.
• PQ cores can be supplied with the center post gapped to a mechanical dimension.
• PQ cores can also be gapped to an A
• A
• See section “The Effect of Direct Current on the Inductance of a Ferrite Core” on page 165 for curves of A
• For any PQ core requirement not listed in the catalog, please contact our customer service group
