1206J2000273MXTE03

Overview

The Knowles Syfer 1206J2000273MXTE03 is an X2Y integrated surface mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features a capacitance of 27 nF with a ±20% tolerance and a DC voltage rating of 200 VDC. The component utilizes X7R dielectric material and offers three terminals for SMD/SMT mounting. It operates within a temperature range of -55°C to +125°C and weighs approximately 10 mg.

Feature Summary

• Integrates X2Y architecture for simultaneous common-mode and differential-mode noise suppression
• Provides superior electromagnetic interference filtering in a compact surface-mount footprint
• Utilizes robust X7R ceramic dielectric for stable performance across wide temperature ranges

Applications

• High-density electronic circuit board layouts requiring effective EMI mitigation
• Power supply input and output stages for noise attenuation
• Signal lines sensitive to both common-mode and differential-mode interference

Procurement Notes

Verify the specific suffix TE03 against official datasheets to confirm terminal plating and packaging details. Ensure compatibility with standard 1206 reflow soldering profiles. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when space constraints necessitate a 1206 footprint but high-performance dual-mode filtering is required. The 200V rating suits applications with moderate voltage stress. Consider the X7R dielectric characteristics for temperature stability requirements within the specified operational range.

Part Context

This part belongs to the Knowles Syfer X2Y IPC-E03 series, designed as integrated passive devices. It replaces discrete capacitor networks by combining multiple filtering functions into a single monolithic structure, thereby reducing board space and improving reliability compared to traditional multi-component solutions.

Replacement Considerations

Direct substitutes include other X2Y capacitors from the same family, such as 1206J2000273MJTE03, which shares identical electrical specifications but may differ in termination or packaging details. Verify pinout and physical dimensions before substitution.
