1206J0250473MXTE07

Overview

The Knowles Syfer 1206J0250473MXTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features a capacitance of 0.047 µF with a tolerance of ±20% and an X7R dielectric material. The component is rated for a DC voltage of 25 V and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations, housed in a standard 1206 (3216 metric) package.

Feature Summary

• Three-terminal feed-through architecture provides inherent EMI filtering capabilities by shunting noise currents to ground.
• Nickel barrier electrode construction ensures reliable solderability and robust mechanical integrity during reflow processes.
• X7R dielectric offers stable capacitance performance across the specified industrial operating temperature range.

Applications

• High-frequency noise suppression in power supply input lines
• EMI filtering for sensitive digital logic circuits
• Signal integrity enhancement in high-speed data transmission paths

Procurement Notes

Verify the complete part number including the suffix MXTE07 to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution may vary by region. Ensure storage conditions align with moisture sensitivity level requirements to prevent package damage during assembly.

Selection Notes

Select this component when compact EMI filtering is required in space-constrained designs. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Verify that the 25V rating meets the circuit's maximum operating voltage. Consider the 1206 footprint compatibility with existing PCB layouts and automated placement equipment capabilities.

Part Context

This component belongs to the Knowles Syfer XT series of high-reliability MLCCs. The series is engineered for demanding electronic environments requiring consistent electrical performance. The specific model integrates filtering functionality directly into the capacitor structure, reducing the need for additional discrete components in the signal path.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Evaluate alternative three-terminal feed-through capacitors from other manufacturers only if they match the 1206 footprint, 25V rating, 0.047 µF capacitance, and X7R dielectric characteristics. Verify terminal configuration and mounting pad layout compatibility before substitution.
