1206J2000222MXTE03

Overview

The Knowles Syfer 1206J2000222MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 2200 pF and a DC voltage rating of 200 V. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It utilizes a three-terminal EMI filter design with nickel barrier and 100% tin terminations, ensuring robust performance for high-frequency noise suppression.

Feature Summary

• Three-terminal EMI filter architecture for enhanced high-frequency noise attenuation
• Nickel barrier and 100% tin termination structure for reliable soldering
• X7R dielectric material providing stable capacitance across wide temperature variations

Applications

• High-frequency noise suppression in sensitive electronic circuits
• EMI filtering in power supply input stages
• Signal integrity protection in communication interfaces

Procurement Notes

Verify the specific ordering suffix against official Knowles Syfer documentation to confirm terminal configuration and packaging details. Ensure compatibility with automated placement equipment regarding the 1206 footprint. Confirm RoHS compliance status through current manufacturer declarations before integration into regulated assemblies.

Selection Notes

Select this component when board space constraints require a compact 1206 footprint alongside effective EMI filtering capabilities. The X7R dielectric provides a balance of cost and performance for general-purpose applications. Consider the three-terminal design advantages over standard two-terminal capacitors for superior high-frequency impedance characteristics.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically designed for surface-mount technology. The 1206J series indicates a 1206 case size with J tolerance coding in some contexts, though this specific part specifies ±20%. It is engineered for reliability in demanding environments, leveraging advanced ceramic processing techniques typical of the Syfer brand portfolio.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 200V rating, 2200pF capacitance, and three-terminal EMI filter topology. Verify that alternative components maintain identical termination materials and thermal stability ratings to ensure circuit performance parity.
