• ESD protection in electronic equipment cabling

Procurement Notes

Verify the specific suffix (e.g., D) against the required datasheet revision. Confirm compliance with RoHS and REACH standards as applicable. Ensure the inner diameter matches the target cable bundle size. Check packaging details such as bulk quantities if specified by the supplier.

Selection Notes

Select based on the required frequency range and cable diameter. The MnZn material offers high impedance at lower frequencies compared to NiZn types. Ensure the operating temperature range meets the environmental requirements of the application. Verify that the physical dimensions allow for adequate clearance in the assembly.

Part Context
