1806Y0250224MXTE01

Overview

The Knowles Syfer 1806Y0250224MXTE01 is a three-terminal EMI filter capacitor designed for surface-mount technology. It features a 0.22 µF capacitance with a 25 VDC voltage rating and ±20% tolerance. The component utilizes C0G dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package measuring 4.5 mm x 1.6 mm x 1.1 mm, it incorporates FlexiCap/Nickel Barrier termination technology to enhance mechanical reliability against board stress.

Feature Summary

• Three-terminal architecture provides effective electromagnetic interference filtering capabilities
• FlexiCap/Nickel Barrier terminations improve resistance to mechanical stress during operation
• C0G dielectric ensures high stability and low loss characteristics

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial electronics
• EMI mitigation in automotive electronic control units

Procurement Notes

Verify the complete part number including the suffix TE01 to confirm the specific reel packaging configuration. Ensure compatibility with the designated FlexiCap termination style for proper soldering profiles. Cross-reference the manufacturer datasheet for precise reflow soldering temperature curves and moisture sensitivity levels before integration into the assembly process.

Selection Notes

Select this component when a compact 1806 footprint is required for three-terminal filtering applications. The C0G dielectric is suitable for circuits demanding minimal capacitance variation over temperature. The 25V rating defines the maximum continuous DC voltage limit; ensure circuit voltages remain within this boundary to maintain device integrity and long-term reliability.

Part Context

This component belongs to the Knowles Syfer Y-series feedthrough capacitors. These devices are engineered specifically for high-density PCB layouts where space constraints necessitate small surface-mount packages. The series integrates filtering functions directly into the capacitor structure, reducing the need for additional discrete components in noise-sensitive designs.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 0.22 µF value, 25V rating, and three-terminal topology. Verify that alternative parts support FlexiCap or compatible nickel barrier terminations to maintain mechanical durability. Confirm identical C0G dielectric properties if temperature stability is critical for the application.
