1806J1000103MXTE01

Overview

The Knowles Syfer 1806J1000103MXTE01 is a surface-mount feed-through capacitor designed for EMI filtering applications. It features a capacitance of 10 nF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it incorporates three terminals for C-filter topology. Key electrical characteristics include a maximum DC resistance of 350 mΩ and a current rating of 300 mA.

Feature Summary

• Integrates a three-terminal C-filter architecture for enhanced high-frequency noise suppression
• Utilizes X7R ceramic dielectric for stable capacitance performance across the operating temperature range
• Features low internal DC resistance to minimize signal attenuation in power lines
• Designed for surface-mount assembly using standard soldering processes

Applications

• EMI filtering in sensitive electronic circuits
• Power line noise suppression in compact devices
• Signal integrity protection in high-density PCB layouts

Procurement Notes

Verify the specific suffix 'E01' indicates the three-terminal configuration when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceable data sheets matching the exact part number to avoid substitution errors with standard two-terminal MLCCs.

Selection Notes

Select this component when space constraints require an 1806 footprint but higher filtering efficiency than standard MLCCs is needed. The three-terminal design offers superior common-mode noise rejection compared to parallel two-terminal capacitors. Evaluate the 300 mA current rating against peak load requirements to prevent thermal issues during operation.

Part Context

This component belongs to the Knowles Syfer series of surface-mount EMI filters. It serves as a specialized alternative to traditional discrete filter components, offering integrated functionality in a small form factor. The product line targets industries requiring reliable noise mitigation in constrained board spaces.

Replacement Considerations

Direct substitutes must match the 1806 package, 10 nF capacitance, and three-terminal structure. Verify that any replacement maintains the same 350 mΩ maximum DC resistance and 300 mA current handling capability to ensure circuit compatibility.
