1206J2000273MJTE03

Overview

The Knowles Syfer 1206J2000273MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed as an X2Y filter. It features a 1206 (3216 metric) package with a capacitance of 27 nF and a voltage rating of 200 VDC. The dielectric material is X7R, providing a tolerance of ±20%. This component integrates three-terminal EMI filtering capabilities within a standard footprint, utilizing a nickel barrier electrode structure.

Feature Summary

• Integrates X2Y three-terminal architecture for simultaneous common-mode and differential-mode noise suppression
• Provides high-frequency electromagnetic interference (EMI) filtering in a compact SMD form factor
• Utilizes nickel barrier construction to enhance reliability against termination corrosion

Applications

• High-density printed circuit boards requiring integrated decoupling and filtering
• Data lines and power rails in portable electronic devices
• Automotive electronics systems subject to strict EMI standards
• Industrial control circuits sensitive to high-frequency noise

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal plating and barrier materials. Ensure compatibility with automated pick-and-place equipment regarding the 1206 package dimensions. Confirm RoHS compliance status through current datasheets before integration into regulated assemblies.

Selection Notes

Select this component when board space is limited but robust EMI suppression is required. The X2Y design reduces the need for discrete components by combining filtering and decoupling functions. Evaluate the 200V rating against peak transient voltages in the target circuit to ensure adequate safety margins during operation.

Part Context

This part belongs to the Knowles Syfer FlexiCap and X2Y product families, which specialize in advanced ceramic filtering solutions. The 1206J series denotes specific dimensional and electrical characteristics within the broader MLCC portfolio. These components are engineered for applications demanding superior signal integrity and noise reduction in constrained spaces.

Replacement Considerations

Direct substitutes include other 1206 X2Y capacitors from Knowles Syfer such as the 1206J2000273MDT or similar variants with matching capacitance and voltage ratings. Verify that alternative parts maintain the same three-terminal configuration and nickel barrier specifications to ensure equivalent performance.
