1806J1000154MXTE01

Overview

The Knowles Syfer 1806J1000154MXTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.15 µF with a 20% tolerance, rated for 100 VDC. The component utilizes C0G dielectric material and operates within a 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 includes a nickel barrier termination and supports a maximum current of 300 mA.

Feature Summary

• Three-terminal feed-through architecture provides effective electromagnetic interference filtering
• C0G dielectric ensures stable capacitance performance across varying temperatures
• Nickel barrier termination enhances solderability and corrosion resistance

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering for DC voltage rails
• EMI mitigation in communication equipment

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and packaging specifications. Confirm that the 300 mA current rating aligns with the application requirements. Check RoHS compliance status through official manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a three-terminal filter topology is required for superior high-frequency attenuation compared to standard two-terminal capacitors. The 1806 footprint offers a balance between capacitance value and board space constraints. Ensure the circuit environment remains within the specified -55°C to +125°C operating range for optimal reliability.

Part Context

This component belongs to the Knowles Syfer E01 series of feed-through capacitors. These devices are engineered specifically for applications demanding robust EMI/RFI suppression in compact surface-mount formats. The series integrates the functionality of a capacitor and a filter into a single monolithic structure.

Replacement Considerations

Direct substitutes must match the 0.15 µF capacitance, 100 VDC rating, 1806 package dimensions, and three-terminal feed-through configuration. Verify compatibility of termination materials and current ratings.
