1206J1000222MCTE01

Overview

The Knowles Syfer 1206J1000222MCTE01 is a surface-mount feed-through capacitor designed for high-frequency EMI suppression. It features a capacitance of 2200 pF with a tolerance of ±20%, rated for 100 VDC and a current rating of 300 mA. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package measuring 3.20 mm x 1.60 mm x 1.30 mm, it provides insertion loss of 27 dB at 100 MHz.

Feature Summary

• Three-terminal feed-through architecture enables effective electromagnetic interference filtering within compact surface-mount layouts.
• C0G/NP0 dielectric construction maintains consistent electrical characteristics and stability under varying thermal conditions.
• High current handling capability supports robust operation in power supply lines and signal paths requiring 300 mA capacity.

Applications

• Electromagnetic interference filtering in DC power distribution networks
• Signal line protection in high-speed digital circuits
• Noise suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix 'E01' corresponds to the required three-terminal feed-through configuration rather than standard two-terminal MLCCs. Confirm that the 1206 footprint dimensions align with the PCB land pattern specifications. Ensure the 300 mA current rating meets the operational requirements of the target circuit application.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete filters. The C0G dielectric ensures minimal capacitance drift over temperature, making it suitable for precision applications. Consider the 1206 package size constraints and verify compatibility with automated placement equipment capabilities.

Part Context

This part belongs to the Knowles Syfer E01 series of surface-mount EMI filter capacitors. These components are engineered to replace traditional discrete filter assemblies by integrating filtering functionality directly into the capacitor structure. The series offers various capacitance values and voltage ratings within standardized SMD packages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and insertion loss characteristics if considering alternative manufacturers' feed-through capacitors.
