1206Y0250683MXTE01

Overview

The Knowles Syfer 1206Y0250683MXTE01 is a three-terminal surface-mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features a 68 nF capacitance with a ±20% tolerance and a 25 VDC voltage rating. The component utilizes X7R dielectric material and incorporates FlexiCap termination technology for enhanced mechanical reliability. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference filtering
• FlexiCap termination technology provides superior resistance to board bending and thermal cycling stress

Applications

• High-frequency noise suppression in electronic circuits
• Power line filtering for sensitive signal integrity
• EMI mitigation in compact surface-mount assemblies

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required termination materials and barrier layers. Confirm that the three-terminal footprint matches the target PCB layout constraints. Cross-reference the voltage derating requirements with the operating environment to maintain long-term reliability under thermal stress conditions.

Selection Notes

Select this component when high-density EMI filtering is required in a standard 1206 footprint. The FlexiCap feature makes it suitable for applications involving mechanical stress or significant thermal cycling. Ensure the circuit current does not exceed the rated limits defined in the manufacturer specifications.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which integrates flexible termination materials to improve durability compared to conventional MLCCs. The three-terminal design distinguishes it from standard two-terminal capacitors by providing a dedicated ground path for improved high-frequency performance.

Replacement Considerations

Direct substitutes must match the 1206 package, 68 nF capacitance, 25V rating, and three-terminal structure. Verify that alternative components support similar thermal cycling resilience if mechanical stress is a factor.

FAQ
