1806J1000472MXTE01

Overview

The Knowles Syfer 1806J1000472MXTE01 is a surface-mount feed-through capacitor designed for EMI filtering applications. It features a capacitance of 0.047 µF with a ±20% tolerance and a DC voltage rating of 100 V. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it provides 40 dB insertion loss at 100 MHz. The device supports a current rating of 300 mA and complies with RoHS3 standards.

Feature Summary

• Three-terminal feed-through architecture for effective electromagnetic interference suppression
• X7R ceramic dielectric providing reliable capacitance stability over wide temperature variations
• High insertion loss characteristics for efficient noise attenuation in signal lines

Applications

• EMI filtering in high-speed digital circuits
• Noise suppression in communication interface ports
• Power line filtering for sensitive electronic components

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct dielectric type and termination plating. Confirm package dimensions match PCB footprint requirements. Check for RoHS3 compliance documentation if required by regional regulations. Validate insertion loss specifications against target frequency ranges during design phase.

Selection Notes

Select this component when X7R dielectric characteristics are suitable for the application environment. Ensure the 100 VDC rating exceeds maximum circuit voltages including transients. Verify that the 1206 package size fits within available board space constraints. Consider the 300 mA current rating for continuous operation limits.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series of SMT EMI filters. It is distinct from general-purpose MLCCs due to its three-terminal ground connection structure. The J series designation indicates specific dimensional and electrical tolerances defined by the manufacturer for consistent integration into filtered designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching capacitance, voltage rating, package size, and insertion loss specifications.
