Overview

The SFAJC1000223MX0 is a Knowles Syfer feedthrough capacitor with a capacitance of 0.022 µF and a voltage rating of 100 VDC. It utilizes X7R dielectric material and offers ±20% tolerance. The component features an axial lead configuration with M3x0.5 threading, measuring 4.00 mm in diameter and 9.20 mm in length. Designed for high reliability, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression through feedthrough architecture
• Features axial leads with integrated threading for secure panel mounting
• Utilizes X7R ceramic dielectric for stable performance across wide temperature ranges

Applications

• Electromagnetic interference filtering in electronic enclosures
• Power supply input/output stages requiring high-frequency noise attenuation
• Military and aerospace systems demanding reliable feedthrough components

Procurement Notes

Verify the specific suffix MX0 against official datasheets to confirm exact mechanical dimensions and termination style. Ensure compatibility with existing panel cutouts for the M3x0.5 thread size. Confirm that the 100V DC rating meets circuit requirements. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when axial mounting and threaded penetration are required for EMI filtering. Compare the 0.022 µF value against circuit impedance needs at target frequencies. Consider the physical envelope of 4.00 mm diameter for space-constrained designs. Evaluate thermal stability requirements against the X7R coefficient characteristics.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor family, designed for robust EMI suppression. These components integrate capacitive elements directly into the conductive path, offering superior high-frequency performance compared to standard discrete capacitors. The series is engineered for harsh environments requiring long-term reliability.

Replacement Considerations

Cross-reference with other SFAJC series variants for different capacitance values or voltage ratings. Verify mechanical fitment before substituting with similar axial feedthrough capacitors from other manufacturers. Ensure equivalent thermal and electrical specifications are maintained.
