1206Y0250563MXTE01

Overview

The Knowles Syfer 1206Y0250563MXTE01 is a surface-mount feed-through capacitor designed for high-reliability applications. It features a capacitance of 0.056 µF with a DC voltage rating of 25V and a tolerance of ±20%. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates flexible terminals and a nickel barrier structure. This design provides effective electromagnetic interference filtering while maintaining mechanical robustness against board flexing.

Feature Summary

• Integrated feed-through architecture providing inherent EMI suppression capabilities within the capacitor structure.
• Flexible terminal construction combined with a nickel barrier to enhance resistance to mechanical stress and board flexing.
• X7R dielectric composition ensures consistent electrical characteristics over a wide industrial temperature range.

Applications

• High-reliability electronic assemblies requiring integrated filtering and decoupling.
• Systems sensitive to mechanical deformation or board flexing during operation.
• Circuits demanding compact surface-mount solutions for electromagnetic interference mitigation.

Procurement Notes

Verify the specific suffix codes against official Knowles Syfer documentation to confirm terminal configuration and barrier materials. Ensure compatibility with automated placement equipment regarding the 1206 footprint dimensions. Cross-reference the X7R dielectric classification with thermal management requirements. Confirm that the 25V rating aligns with peak circuit voltages. Validate RoHS compliance status through current manufacturer declarations before integration.

Selection Notes

Select this component when space constraints necessitate a 1206 footprint but higher filtering efficiency than standard MLCCs is required. The flexible terminal option is critical for applications involving rigid boards subject to bending. Compare the 0.056 µF value against circuit impedance requirements at target frequencies. Consider the nickel barrier feature if environmental durability is a priority. Evaluate alternative voltage ratings only if system conditions exceed 25V DC.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with enhanced mechanical resilience. The 1206Y prefix indicates a 1206 case size with specific terminal and barrier configurations. As a feed-through device, it differs from conventional two-terminal capacitors by offering superior high-frequency noise attenuation. The series targets industries where reliability under physical stress is paramount.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 0.056 µF capacitance, 25V rating, and feed-through topology. Verify that any replacement maintains the flexible terminal and nickel barrier specifications to preserve mechanical integrity. Standard MLCCs without feed-through structures will not provide equivalent EMI filtering performance.
