1206Y0250204MXTE07

Overview

The Knowles Syfer 1206Y0250204MXTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features a 1206 (3216 metric) package size with a rated DC voltage of 25V and a capacitance value of 200nF. The dielectric material is X7R, providing a tolerance of ±20%. This component incorporates FlexiCap technology with a nickel barrier and tin termination to enhance mechanical reliability.

Feature Summary

• Three-terminal feed-through architecture provides integrated EMI filtering capabilities within the capacitor structure.
• FlexiCap flexible terminal design reduces stress on the PCB substrate during thermal cycling and board flexing.
• Nickel barrier layer protects the internal electrode structure from solder wicking during the reflow process.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input/output filtering for digital logic boards
• EMI mitigation in compact mobile device power traces

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm terminal composition and barrier requirements. Ensure the ordering quantity aligns with standard reel packaging constraints defined by Knowles Syfer. Cross-reference the RoHS compliance status with current environmental regulations applicable to your manufacturing region before finalizing procurement orders.

Selection Notes

Select this component when both high capacitance density and electromagnetic interference suppression are required in a single surface-mount footprint. The three-terminal configuration offers superior high-frequency performance compared to standard two-terminal capacitors. Evaluate the 25V rating against peak transient voltages to ensure adequate margin for long-term circuit stability.

FAQ

What is the primary function of the nickel barrier in this component?

The nickel barrier prevents solder from wicking into the internal electrodes during the reflow soldering process, ensuring consistent electrical performance and structural integrity.

How does the three-terminal design benefit EMI filtering?

The three-terminal feed-through structure provides a low-inductance path to ground, significantly improving high-frequency noise attenuation compared to conventional two-terminal capacitors.
