1206J0500272MJTE03

Overview

The Knowles Syfer 1206J0500272MJTE03 is a multilayer ceramic feedthrough capacitor designed for surface mount technology. It features a capacitance of 2700 pF with a DC voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes a C0G dielectric material, ensuring stability across an operating temperature range from -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it provides three terminals for effective electromagnetic interference filtering in compact electronic assemblies.

Feature Summary

• Integrates feedthrough architecture within a standard surface mount footprint for enhanced EMI suppression
• Utilizes C0G dielectric material to maintain capacitance stability under varying thermal conditions
• Features three-terminal construction to minimize parasitic inductance during high-frequency operation

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• Electromagnetic interference suppression in automotive electronics

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with existing PCB footprints, as feedthrough capacitors require distinct pad layouts compared to standard two-terminal MLCCs. Cross-reference part numbers with authorized distributors to confirm current availability status and lead times.

Selection Notes

Select this component when space-constrained designs require superior high-frequency noise attenuation without increasing board area. The three-terminal design offers lower impedance paths for common-mode noise compared to conventional capacitors. Confirm that the 50V DC rating aligns with the maximum circuit voltage peaks to ensure long-term reliability and prevent dielectric breakdown.

Part Context

This component belongs to the Knowles Syfer family of high-reliability passive components. The 1206J series designation indicates a surface mount form factor optimized for automated assembly processes. As a specialized feedthrough device, it differs from standard chip capacitors by providing integrated shielding capabilities within the ceramic body structure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility before considering alternative manufacturers, as feedthrough capacitor terminal arrangements vary significantly between brands.
