1806Y0250223MXTE07

Overview

The Knowles Syfer 1806Y0250223MXTE07 is a Surface Mount Device (SMD) Multilayer Ceramic Capacitor (MLCC) designed for EMI filtering applications. It features a 1806 case size with a capacitance of 22 nF, a voltage rating of 25 VDC, and a tolerance of ±20%. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. This component utilizes the FlexiCap technology with a nickel barrier, offering enhanced mechanical robustness against cracking during soldering processes.

Feature Summary

• Incorporates FlexiCap technology with a nickel barrier to improve mechanical reliability and resistance to termination cracking.
• Functions as a three-terminal EMI filter capacitor, providing effective noise suppression in high-frequency circuits.
• Utilizes X7R ceramic dielectric to maintain capacitance stability over a wide operating temperature range.

Applications

• High-frequency signal line filtering in consumer electronics
• Power supply input/output decoupling in compact devices
• EMI suppression in automotive infotainment systems

Procurement Notes

Verify the specific suffix codes on the ordering information to ensure compatibility with your assembly requirements. Confirm that the FlexiCap termination style matches your PCB pad design specifications. Check the latest datasheet for any updates regarding RoHS compliance status or environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when space constraints require an 1806 footprint but higher mechanical durability than standard MLCCs is needed. The three-terminal structure offers superior high-frequency attenuation compared to two-terminal equivalents. Ensure the 25V DC rating provides sufficient margin for the maximum circuit voltage including transients.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in mechanically robust ceramic capacitors. The 'Y' designation typically indicates the FlexiCap/Nickel Barrier construction within the product coding system. It is distinct from standard MLCCs by its specialized termination structure designed to withstand thermal stress during reflow soldering.

Replacement Considerations

Direct replacements must match the 1806 case size, 22nF capacitance, 25V rating, and X7R dielectric. Verify if the application requires the specific mechanical benefits of the FlexiCap nickel barrier; otherwise, standard X7R MLCCs may suffice. Cross-reference with other manufacturers' 1806 EMI filter capacitors ensuring identical terminal configuration.
