1806Y0500222MJTE07

Overview

The Knowles Syfer 1806Y0500222MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 3-terminal architecture within an 1806 (4516 metric) package, providing a capacitance of 2200 pF with a voltage rating of 50 VDC and a current handling capacity of 2 A. The component utilizes X7R dielectric characteristics and incorporates a nickel barrier termination structure to enhance reliability in high-reliability applications.

Feature Summary

• Three-terminal feed-through architecture enables effective common-mode noise attenuation by grounding the center terminal while passing signal through the outer terminals.
• Nickel barrier termination technology provides robust solderability and resistance to corrosion, ensuring long-term connection integrity in harsh environments.

Applications

• High-speed data line filtering in telecommunications equipment
• EMI suppression for USB and HDMI interfaces in consumer electronics
• Noise reduction in automotive infotainment and sensor systems

Procurement Notes

Verify the specific suffix 'MJTE07' against the manufacturer's latest datasheet to confirm the exact termination material and reel packaging specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions and recommended soldering profile for nickel-barrier terminations.

Selection Notes

Select this component when space-constrained designs require superior high-frequency noise attenuation compared to standard two-terminal MLCCs. The 3-terminal design offers lower parasitic inductance, making it suitable for frequencies where standard capacitors lose effectiveness. Confirm that the 2 A current rating meets the operational requirements of the protected circuit.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in multi-terminal ceramic filters. The 1806 case size balances physical footprint with electrical performance, offering higher capacitance density than smaller packages while maintaining low profile for compact PCB layouts.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 3-terminal feed-through topology, and 2200 pF capacitance. Verify equivalent voltage ratings and termination materials to ensure mechanical and electrical compatibility without redesigning the PCB layout.
