1206J0500221MCTE01

Overview

The Knowles Syfer 1206J0500221MCTE01 is a three-terminal feedthrough capacitor designed for surface mount technology. It features a capacitance of 220 pF with a DC voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it provides integrated EMI filtering capabilities suitable for high-frequency noise suppression applications.

Feature Summary

• Integrates three-terminal feedthrough architecture for enhanced electromagnetic interference suppression
• Provides compact surface-mount footprint compatible with automated assembly processes
• Utilizes stable X7R ceramic dielectric for consistent performance across operating temperatures

Applications

• High-frequency noise filtering in sensitive electronic circuits
• Electromagnetic interference suppression in communication modules
• Power line conditioning in compact consumer electronics

Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to ensure correct terminal plating and barrier layer specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference the full part number with authorized distributor catalogs to validate current availability and manufacturing lifecycle status.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without additional discrete components. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Ensure the 50V DC rating aligns with circuit operating voltages and that the 1206 package dimensions fit the designated PCB layout constraints.

Part Context

This component belongs to the Knowles Syfer X2Y IPC-E03 series of integrated surface-mount EMI filters. These devices combine decoupling and filtering functions into a single package, reducing board space and improving signal integrity. The series is engineered for demanding applications requiring reliable noise suppression in compact form factors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative three-terminal feedthrough capacitors from other manufacturers based on capacitance, voltage rating, and package dimensions.
