1206J0250273MJTE07

Overview

The Knowles Syfer 1206J0250273MJTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed as an EMI filter. It features a 1206 surface-mount package with a capacitance of 27 nF and a voltage rating of 25 VDC. The dielectric material is X7R, providing a tolerance of ±20%. This component utilizes a nickel barrier electrode structure with 100% tin terminations to ensure reliable solderability and performance in high-frequency applications.

Feature Summary

• Three-terminal architecture for enhanced electromagnetic interference suppression
• Nickel barrier internal electrodes combined with 100% tin external terminations
• X7R dielectric composition for stable capacitance across operating temperatures

Applications

• High-frequency noise filtering in electronic circuits
• Power supply input/output decoupling
• Signal line EMI suppression

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to confirm specific termination and packaging details. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm RoHS compliance status through current datasheets before integration into regulated products.

Selection Notes

Select this component when integrated EMI filtering is required within a standard MLCC footprint. The three-terminal design offers superior high-frequency attenuation compared to two-terminal capacitors. Verify that the 25V rating and 27nF value meet circuit requirements without exceeding thermal or electrical limits during operation.

Part Context

This component belongs to the Knowles Syfer Syfer Filter series, which specializes in application-specific multilayer ceramic capacitors. These devices integrate filtering capabilities directly into the capacitor structure, reducing board space and simplifying design by combining energy storage with noise suppression functions.

Replacement Considerations

Direct substitutes must match the 1206 package, 27nF capacitance, 25V rating, X7R dielectric, and three-terminal EMI filter configuration. Verify terminal material and barrier layer specifications to ensure equivalent solderability and reliability.
