1806Y0250204MJTE07

Overview

The Knowles Syfer 1806Y0250204MJTE07 is a Surface Mount Device (SMD) multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1806 (4516 metric) case size with a nominal capacitance of 200 nF and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It offers a capacitance tolerance of ±20% and employs flexible end terminations to enhance mechanical robustness against board stress.

Feature Summary

• Flexible end termination design reduces susceptibility to cracking during thermal cycling and mechanical stress
• X7R dielectric provides consistent capacitance stability over a wide operating temperature range
• High reliability construction suitable for demanding electronic environments

Applications

• General purpose decoupling in high-reliability circuits
• Filtering applications requiring stable capacitance under thermal variation
• Automotive electronics components
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix to ensure the correct termination style and packaging configuration match your assembly requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the full part number with authorized distributors to ensure authenticity and traceability of the component batch.

Selection Notes

Select this component when a 1806 footprint is required with moderate capacitance values. The X7R dielectric is appropriate for general filtering where tight tolerance is not critical. Ensure the 50V rating exceeds the maximum circuit voltage including transients. Consider the flexible termination benefits if the PCB layout involves significant mechanical strain or thermal expansion mismatches.

Part Context

This component belongs to the Knowles Syfer portfolio of specialized MLCCs. The brand focuses on application-specific capacitors and EMI suppression filters. The 1806Y series indicates a standard 1806 case size with Y denoting the voltage code within the product line. These parts are engineered for sectors requiring higher durability than standard commercial grade capacitors.

Replacement Considerations

Direct substitutes must match the 1806 case size, 50V rating, 200nF capacitance, X7R dielectric, and flexible termination style. Verify that alternative manufacturers offer equivalent thermal and mechanical specifications. Ensure pin compatibility and footprint alignment before replacing the original part.
