1206Y0250154MXTE07

Overview

The Knowles Syfer 1206Y0250154MXTE07 is a three-terminal feed-through capacitor designed for surface mount technology. It features a capacitance of 0.15 µF with a tolerance of ±20% and a rated DC voltage of 25 V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. It incorporates FlexiCap™ flexible terminations and a nickel barrier structure to enhance mechanical reliability. The package dimensions conform to the standard 1206 (3216 metric) footprint, suitable for high-frequency noise suppression applications.

Feature Summary

• Three-terminal feed-through architecture providing superior high-frequency EMI filtering performance compared to standard two-terminal capacitors.
• FlexiCap™ flexible termination design reduces stress on the capacitor body and PCB pads during board flexing or thermal cycling.
• Nickel barrier layer integrated into the termination structure to prevent solder wicking and ensure robust solder joint integrity.

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive electronic modules
• EMI suppression in automotive infotainment and control units

Procurement Notes

Verify the complete part number including the suffix to confirm specific termination and packaging configurations. Ensure compatibility with reflow soldering profiles specified in the official datasheet. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when board space constraints require a 1206 footprint but higher filtering efficiency than standard MLCCs is needed. The three-terminal design offers lower parasitic inductance. Consider the FlexiCap feature if the application involves mechanical stress or significant thermal expansion mismatches between the component and the substrate.

Part Context

This component belongs to the Knowles Syfer Syfer® series of advanced ceramic capacitors. The series emphasizes reliability in harsh environments through specialized termination technologies. The 1206Y prefix indicates a 1206 case size with specific electrical characteristics defined by the manufacturer's internal coding system for voltage and capacitance values.

Replacement Considerations

Direct substitutes must match the 0.15 µF capacitance, 25 V rating, X7R dielectric, and three-terminal feed-through topology. Verify that alternative components support the same 1206 footprint and offer comparable FlexiCap or equivalent flexible termination features to maintain mechanical reliability standards.
