1206J0250123MXTE07

Overview

The Knowles Syfer 1206J0250123MXTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 0.012 µF with a tolerance of ±20% and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, ensuring stability across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier and tin termination system. This configuration provides effective electromagnetic interference filtering capabilities within compact electronic assemblies.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Nickel barrier and tin termination system for reliable soldering
• X7R dielectric material for stable performance across wide temperature ranges

Applications

• Electromagnetic interference filtering in high-density circuit boards

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation before procurement. Confirm that the specific ordering code matches the required nickel barrier and tin termination specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference datasheet revisions to confirm electrical characteristics remain unchanged for the intended application environment.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete components. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Consider the 1206 footprint constraints and ensure the 25V rating meets the circuit's maximum operating voltage requirements while maintaining adequate derating margins.

Part Context

This component belongs to the Knowles Syfer Flexicap series, which integrates capacitor functionality with EMI filtering in a single surface-mount device. The series is engineered for applications requiring robust noise reduction in sensitive analog and digital circuits. The 1206J variant specifically denotes the standard 1206 case size with J tolerance coding, aligning with industry-standard packaging dimensions for automated assembly processes.
