1206Y2000273MXTE03

Overview

The Knowles Syfer 1206Y2000273MXTE03 is a surface-mount feed-through capacitor in a 1206 (3216 metric) package. It features a capacitance of 0.027 µF with a voltage rating of 200 VDC and a tolerance of ±20%. The dielectric material is X7R, providing stability across an operating temperature range of -55°C to +125°C. This component utilizes FlexiCap technology with nickel barrier electrodes for enhanced mechanical reliability.

Feature Summary

• Integrated feed-through architecture combining filtering and decoupling functions within a single SMD footprint
• FlexiCap flexible terminal design reduces stress on the ceramic body during board flexing events
• Nickel barrier electrode structure provides robust adhesion between the dielectric layers and terminations

Applications

• High-density PCB layouts requiring combined EMI suppression and power distribution stabilization
• Automotive electronic modules subject to mechanical vibration and thermal cycling
• Telecommunications infrastructure equipment demanding reliable signal integrity in compact form factors

Procurement Notes

Verify the specific suffix MXTE03 against official datasheets to confirm the feed-through configuration and termination specifications. Ensure compatibility with reflow soldering profiles recommended for FlexiCap components. Confirm that the 1206 footprint matches the target PCB land pattern dimensions precisely.

Selection Notes

Select this component when space constraints prevent the use of discrete capacitors and inductors. The feed-through design offers superior high-frequency attenuation compared to standard parallel capacitors. Evaluate the 200V rating against peak circuit voltages to ensure adequate margin under transient conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series addresses common failure modes associated with board flex and thermal shock in automotive and industrial applications through its unique flexible termination technology.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor and 200V rating. Verify that alternative parts support the same X7R dielectric characteristics and FlexiCap-style terminations to maintain mechanical reliability in flex-sensitive environments.
