1206J0500222MCTE01

Overview

The Knowles Syfer 1206J0500222MCTE01 is a surface-mount feed-through capacitor designed for EMI filtering applications. It features a capacitance of 2200 pF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it provides a current rating of 300 mA and achieves an insertion loss of 43 dB at 100 MHz.

Feature Summary

• Integrates feed-through architecture within a compact SMD form factor for efficient PCB space utilization
• Delivers high attenuation performance suitable for suppressing electromagnetic interference signals
• Maintains electrical stability through C0G/NP0 ceramic dielectric construction

Applications

• General EMI filtering in electronic circuits
• Signal line protection in communication equipment
• Power supply input filtering for low-voltage systems

Procurement Notes

Verify the complete part number including the E01 suffix to ensure correct termination and packaging specifications. Confirm that the 50V rating and 300mA current limit align with the target circuit requirements. Check RoHS compliance status and moisture sensitivity level before assembly planning. Ensure compatibility with standard reflow soldering profiles for 1206 packages.

Selection Notes

Select this component when high-frequency noise suppression is required in space-constrained designs. The 1206 footprint allows for direct replacement of larger through-hole filters. Consider the 50V rating for low-voltage signal lines rather than high-power applications. The C0G dielectric ensures minimal capacitance drift under varying thermal conditions.

Part Context

This component belongs to the Knowles Syfer E01 series of surface-mount EMI filter capacitors. The series is characterized by its feed-through structure, which integrates the capacitor element directly into the signal path. These components are engineered to provide superior high-frequency attenuation compared to standard MLCCs while maintaining a small profile suitable for modern dense PCB layouts.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and dimensional compatibility if considering alternative manufacturers' feed-through capacitors.
