1806J1000473MXTE01

Overview

The Knowles Syfer 1806J1000473MXTE01 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features a capacitance of 0.047 µF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package measuring 4.5 mm x 1.6 mm x 1.3 mm, it supports a current rating of 300 mA and provides 18 dB insertion loss at 100 MHz.

Feature Summary

• Three-terminal EMI filter architecture for effective noise suppression
• C0G/NP0 dielectric for high stability and low loss
• Surface mount compatibility with standard reflow processes

Applications

• High-frequency signal line filtering
• Power supply decoupling in sensitive circuits
• EMI suppression in communication modules

Procurement Notes

Verify the specific voltage rating and current handling capabilities against the target circuit requirements before integration. Confirm that the 1806 footprint dimensions align with the PCB land pattern design. Ensure compliance with RoHS3 standards if required by the final assembly specifications.

Selection Notes

Select this component when compact EMI filtering is required for signals up to several hundred megahertz. The C0G dielectric ensures minimal capacitance drift with temperature and voltage changes. Consider the 300 mA current limit when designing power distribution networks to prevent thermal issues during operation.

Part Context

This part belongs to the FlexiCap series of feed-through capacitors from Knowles Syfer. These components integrate capacitor and inductor functions into a single surface-mount device, offering superior high-frequency attenuation compared to traditional two-terminal MLCCs. The 1806 package size balances performance with board space efficiency.
