1206J0500473MXTE01

Overview

The Knowles Syfer 1206J0500473MXTE01 is a three-terminal EMI filter capacitor in a 1206 (3216 metric) surface-mount package. It features a 47 nF capacitance with ±20% tolerance and a 50 VDC voltage rating. The component utilizes X7R dielectric material and offers nickel barrier termination with 100% tin plating. Designed for high-frequency noise suppression, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Nickel barrier termination structure ensures reliable solderability and mechanical stability during surface mount assembly processes.
• X7R ceramic dielectric maintains stable capacitance characteristics across the specified industrial operating temperature range.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering for DC voltage rails
• Signal integrity protection in communication interfaces

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact termination and packaging specifications. Ensure compatibility with existing PCB footprint designs before integration. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve over time.

Selection Notes

Select this component when superior common-mode noise attenuation is required in space-constrained designs. The three-terminal configuration allows for lower effective series inductance compared to standard MLCCs. Evaluate thermal management requirements to ensure operation remains within the -55°C to +125°C specification limits.

Part Context

This part belongs to the Knowles Syfer Flexicap family of multilayer ceramic capacitors. These components are engineered for high reliability applications requiring robust mechanical performance under thermal cycling conditions. The product line is recognized for its specialized termination technology designed to withstand board flexing without cracking.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 47 nF capacitance, 50V rating, and three-terminal EMI filter topology. Verify that alternative components offer comparable insertion loss characteristics and meet the same environmental qualification standards.
