Pot Cores
Dimensions
*Bold part numbers designate preferred parts.
The pot core has found wide application in all types of inductive devices. The core configuration
provides a high degree of self-shielding. It also facilitates gapping to enhance its utility for a
variety of magnetic designs.
• Part number is for a single core.
• Pot cores in 78 material can be supplied with the center post gapped to a mechanical dimension.
• Pot cores in 78 material can also be gapped to an A
• Pot cores sets that have an airgap in one of the core halves will be marked with a white marking on the backwall.
• A
• See section “The Effect of Direct Current on the Inductance of a Ferrite Core” on page 165 for curves of A
• The pot cores shown in Figure 1 are in conformance with IEC 60133.
• For any pot core requirement not listed in the catalog, please contact our customer service group for
