1206J0500124MJTE03

Overview

The Knowles Syfer 1206J0500124MJTE03 is a surface-mount feedthrough capacitor with a capacitance of 0.12 µF and a DC voltage rating of 50 VDC. It features a 1206 (3216 metric) package, three terminals, and a tolerance of ±20%. The component operates within a temperature range of -55°C to +125°C and utilizes an X7R dielectric.

Feature Summary

• Integrated EMI filtering via X2Y architecture
• Three-terminal pass-through design for efficient PCB routing
• High thermal stability across extended industrial temperature ranges

Applications

• High-frequency noise suppression in data lines
• Power supply input filtering for sensitive electronics
• EMI mitigation in compact mobile devices

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct dielectric type and termination specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows.

Selection Notes

Select this component when space-constrained EMI filtering is required without additional discrete components. Ensure the 50V rating exceeds peak circuit voltages and the 1206 footprint aligns with existing board layout constraints.

Part Context

This part belongs to the Knowles Syfer FlexiCap series of integrated surface-mount EMI filters. These components combine capacitive elements with shielding to provide superior high-frequency attenuation compared to standard multilayer ceramic capacitors.

Replacement Considerations

Cross-reference with other 1206 J-series feedthrough capacitors from Knowles Syfer or compatible third-party manufacturers offering identical 0.12 µF capacitance and 50V ratings.
