1206J2000221MCTE03

Overview

The Knowles Syfer 1206J2000221MCTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) package. It features a C0G/NP0 dielectric with a capacitance of 220 pF and a tolerance of ±20%. The component has a DC voltage rating of 200 VDC and utilizes a nickel barrier electrode structure with 100% tin terminations. Designed for high-frequency applications, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• X2Y architecture providing integrated common-mode filtering capabilities
• C0G/NP0 dielectric ensures stable capacitance across varying temperatures
• Nickel barrier electrode construction for enhanced reliability

Applications

• High-frequency signal filtering in RF circuits
• Common-mode noise suppression in data lines
• Decoupling applications requiring low parasitic inductance

Procurement Notes

Verify the specific suffix 'E03' against the manufacturer's official datasheet to confirm termination style and packaging configuration. Ensure compatibility with standard reflow soldering profiles for 1206 MLCCs. Confirm RoHS compliance status through current regulatory documentation before integration into final assemblies.

Selection Notes

Select this component when board space constraints require a compact 1206 footprint combined with X2Y filtering functionality. The C0G dielectric is suitable for circuits demanding minimal capacitance variation over temperature. Verify that the 200V DC rating meets the peak voltage requirements of the target application circuit.

Part Context

This part belongs to the Knowles Syfer general-purpose MLCC line utilizing X2Y technology. The X2Y design integrates three capacitive elements within a single package to provide superior high-frequency performance compared to standard two-terminal capacitors. It serves as a compact solution for EMI suppression in dense PCB layouts.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 220pF value, 200V rating, and X2Y topology. Verify equivalent parasitic parameters such as ESL and resistance. Standard two-terminal C0G capacitors are not functional replacements due to the lack of integrated filtering.
