Z21E

Overview

The Z21E is a two-line common mode choke manufactured by Ohmite, designed for power line applications. It features an axial lead termination and is shielded to minimize electromagnetic interference. The component supports a current rating of 10A with a direct current resistance (DCR) of 70mOhm. It is classified as a power line choke and falls under the filter product category.

Feature Summary

• Two-line common mode filtering capability
• Shielded construction for EMI reduction
• Axial lead termination style

Applications

• Power line filtering
• Electromagnetic interference suppression in electronic circuits

Procurement Notes

Verify the specific datasheet for detailed electrical characteristics and mechanical dimensions before integration. Confirm that the axial lead configuration matches the target PCB layout or wiring harness requirements. Ensure the 10A current rating and 70mOhm DCR align with the system's power management specifications. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a shielded, two-line common mode choke is required for power lines. The 10A rating suits moderate power applications. The axial package dictates through-hole mounting. Compare performance against unshielded alternatives if space constraints allow, but prioritize this model for its specified shielding and low DCR characteristics.

Part Context

The Z21E belongs to Ohmite's range of passive components, specifically within the filter and choke segment. It serves as a solution for noise suppression in power distribution networks. Unlike resistors from the same manufacturer, such as the Dividohm series, this part focuses on magnetic filtering rather than resistance adjustment.

Replacement Considerations

Consult official distributor databases for cross-references. Verify pin compatibility and impedance curves for any substitute parts to ensure equivalent noise suppression performance.
