1206J0500273MJTE07

Overview

The Knowles Syfer 1206J0500273MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features a 1206 package size with a capacitance of 27 nF and a voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing a tolerance of ±20%. It incorporates a three-terminal architecture with a nickel barrier and 100% tin termination system to enhance electromagnetic interference suppression.

Feature Summary

• Three-terminal structure optimized for common-mode noise attenuation
• Nickel barrier termination system ensuring reliable solderability
• X7R dielectric composition for stable performance across operating temperatures

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Signal line protection in communication devices
• Power supply input/output noise suppression

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status through current datasheets. Check availability constraints as distribution may vary by region. Ensure storage conditions align with MLCC handling guidelines to prevent moisture sensitivity issues before reflow soldering.

Selection Notes

Select this component when specific EMI filtering requirements exist within a 1206 footprint constraint. The three-terminal design offers superior high-frequency noise reduction compared to standard two-terminal capacitors. Verify that the 50V DC rating meets circuit voltage demands with appropriate derating margins. Consider the X7R temperature characteristics for environmental stability requirements.

Part Context

This component belongs to the Knowles Syfer EMI filter capacitor series. These parts are engineered specifically for suppressing electromagnetic interference in compact surface-mount designs. The product line emphasizes reliability and consistent performance in demanding electronic environments, utilizing advanced ceramic materials and specialized internal electrode structures.

Replacement Considerations

Direct substitutes must match the 1206 package, 27nF capacitance, 50V rating, X7R dielectric, and three-terminal configuration. Verify terminal material compatibility and mounting orientation requirements. Cross-reference electrical parameters and physical dimensions to ensure board-level interchangeability without redesign.
