1206Y0250823MXTE01

Overview

The Knowles Syfer 1206Y0250823MXTE01 is a three-terminal EMI filter capacitor housed in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 82 nF and a DC voltage rating of 25 VDC. The component has a tolerance of ±20% and utilizes FlexiCap technology for flexible terminations to enhance board reliability. It operates within a temperature range of -55°C to +125°C and is supplied in reel packaging.

Feature Summary

• Three-terminal architecture provides effective electromagnetic interference filtering
• FlexiCap flexible terminations reduce stress on the ceramic body and PCB pads
• X7R dielectric material ensures stable performance across wide temperature variations

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering in compact surface-mount designs
• EMI mitigation in mobile and portable devices

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination style and packaging configuration. Confirm that the supplier provides official datasheets matching the Knowles Syfer specifications. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the source is an authorized distributor to guarantee component authenticity and traceability.

Selection Notes

Select this component when space constraints require a 1206 footprint but superior EMI filtering is needed compared to standard two-terminal capacitors. The flexible terminations make it suitable for applications subject to mechanical stress or board flexing. Consider the 25V rating and 82nF value against circuit requirements for adequate noise attenuation without excessive size.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family, specifically designed for demanding environments. The 1206Y series integrates filtering capabilities directly into the capacitor structure, combining energy storage with signal integrity protection. It represents a specialized solution for designers prioritizing compact form factors and robust electromagnetic compatibility.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 25V rating, 82nF capacitance, and three-terminal EMI filter topology. Verify that alternative components also feature flexible terminations if board stress relief is critical. Ensure the replacement maintains the same X7R dielectric characteristics and operating temperature range.
