1206J0250124MXTE07

Overview

The Knowles Syfer 1206J0250124MXTE07 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 0.12 µF with a voltage rating of 25 VDC and an X7R dielectric material. The component operates within a temperature range of -55°C to +125°C and provides a current handling capacity of 2 A. It utilizes a nickel barrier with 100% tin terminations in a standard 1206 (3216 metric) package.

Feature Summary

• Three-terminal feed-through architecture providing integrated EMI filtering capabilities
• Nickel barrier termination structure ensuring robust solderability and reliability
• High current handling capability suitable for power line applications

Applications

• EMI suppression on DC power input lines
• Signal conditioning in sensitive electronic circuits
• Board-level noise filtering for high-speed digital systems

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the datasheet for specific footprint dimensions and recommended soldering profiles to prevent mechanical stress during assembly.

Selection Notes

Select this component when board space constraints require integrated filtering without additional discrete components. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Ensure the operating voltage remains below the 25 VDC rating and that thermal conditions stay within the specified -55°C to +125°C range for long-term stability.

Part Context

This component belongs to the Knowles Syfer MLCC family, specifically engineered for high-reliability applications. The 1206J series denotes general-purpose X7R characteristics, while the MXTE07 suffix indicates the specific three-terminal feed-through construction with nickel barrier terminations. This configuration distinguishes it from standard parallel-plate capacitors by offering enhanced electromagnetic interference rejection.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1206 package dimensions. Verify equivalent capacitance, voltage rating, and current handling capabilities. Standard two-terminal capacitors are not functionally equivalent due to differing filtering performance.
