1806J1000220MCTE01

Overview

The Knowles Syfer 1806J1000220MCTE01 is a three-terminal feed-through capacitor designed for surface mount applications. It features a capacitance of 22 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes C0G dielectric material, ensuring stability across an operating temperature range from -55°C to +125°C. Housed in the standard 1806 (4516 metric) package, it measures 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. Key electrical characteristics include a maximum DC resistance of 0.35 Ω and a minimum insulation resistance of 10,000 MΩ.

Feature Summary

• Three-terminal EMI filter architecture providing effective noise suppression
• Nickel barrier termination structure for enhanced reliability
• C0G dielectric composition for stable capacitance performance

Applications

• High-frequency signal line filtering
• Power supply input/output decoupling
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal plating and packaging details. Ensure compatibility with surface mount assembly processes by checking footprint dimensions. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated products.

Selection Notes

Select this component when high-frequency noise attenuation is required in space-constrained designs. The three-terminal topology offers superior high-frequency performance compared to standard two-terminal capacitors. Verify that the 100V rating and 22pF value align with circuit requirements for optimal filtering efficiency.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which integrates capacitor functionality within a single SMD package. These components are engineered for compact PCB layouts where traditional discrete filters would occupy excessive board area. The series targets applications demanding robust EMI/RFI mitigation in modern electronic systems.

Replacement Considerations

Consult official substitution guides for equivalent three-terminal feed-through capacitors with matching 1806 dimensions and 100V ratings. Verify that alternative parts maintain similar insertion loss characteristics and thermal stability profiles.
