SFJEC3K00221MC0

Overview

The Knowles Syfer SFJEC3K00221MC0 is a feedthrough capacitor rated at 3 kV DC with a capacitance of 220 pF and ±20% tolerance. It utilizes C0G (NP0) dielectric for stable performance across a temperature range of -55°C to +125°C. The component features an axial, flange-mount package with dimensions of 9.80 mm diameter by 9.40 mm length. It includes a 1/4-28 thread specification for secure installation.

Feature Summary

• Provides high-voltage EMI filtering through a robust flange-mount design
• Maintains electrical stability using C0G/NP0 ceramic dielectric material
• Ensures mechanical security via integrated 1/4-28 threaded mounting interface

Applications

• High-voltage power supply input filtering
