SFJEC3K00221MC1

Overview

The SFJEC3K00221MC1 is an EMI feedthrough filter from the Knowles Syfer SFJE series. It features a capacitance of 220 pF with a tolerance of ±20%. The device has a DC voltage rating of 3 kV and a current rating of 15 A. It utilizes C0G (NP0) dielectric material for stable performance. The component is housed in an axial bushing package with dimensions of 9.80 mm diameter by 9.40 mm length.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough filtering architecture
• Utilizes C0G (NP0) ceramic dielectric for consistent electrical characteristics across temperature ranges
• Designed for high-voltage applications with a 3 kV DC rating
• Supports continuous current loads up to 15 A

Applications

• High-voltage power supply input filtering
• Electromagnetic interference suppression in sensitive electronic circuits
• Industrial equipment requiring robust EMI protection

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact mechanical and electrical tolerances. Confirm RoHS compliance status as required by project specifications. Check for obsolete status or lifecycle changes before finalizing design-in decisions. Ensure the axial bushing mounting style matches the chassis penetration requirements of the target enclosure.

Selection Notes

Select this component when high-voltage isolation and significant current handling are required alongside EMI filtering. The 220 pF value offers a balance between low-frequency attenuation and minimal impact on signal integrity for control lines. Consider the physical dimensions for panel cutout compatibility. Evaluate the 15 A current rating against peak load requirements to prevent thermal issues.
