1806Y0500124MJTE07

Overview

The Knowles Syfer 1806Y0500124MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 3-terminal C-filter topology within an EIA 1806 (4516 metric) package measuring 4.5 mm x 1.6 mm x 1.3 mm. The component offers a capacitance of 0.12 µF with a ±20% tolerance, rated for 50 VDC. It utilizes X7R dielectric material and supports a maximum current of 2 A. Operating temperatures range from -55 °C to +125 °C.

Feature Summary

• Integrates a three-terminal C-filter architecture for effective electromagnetic interference attenuation in compact layouts.
• Incorporates a nickel barrier termination system to enhance solderability and mechanical reliability during surface mount assembly.

Applications

• Electromagnetic interference filtering in high-density electronic circuits
• Power line conditioning for sensitive signal paths
• Component protection in automotive and industrial control systems

Procurement Notes

Verify the complete part number including suffixes against official Knowles Syfer documentation to ensure correct dielectric type and termination specifications. Confirm RoHS compliance status and specific packaging options such as cut tape or reel quantities directly with authorized distributors prior to ordering.

Selection Notes

Select this component when space constraints require a 1806 footprint but higher current handling than standard MLCCs is needed. The 3-terminal design provides superior high-frequency noise suppression compared to 2-terminal capacitors. Ensure the circuit voltage does not exceed the 50 VDC rating and that the operating temperature remains within the specified -55 °C to +125 °C range.

Part Context

This device belongs to the Knowles Syfer series of surface-mount EMI filters. These components are engineered to replace traditional discrete filter assemblies, offering significant size reduction while maintaining robust performance in demanding environments. The product line emphasizes reliability through specialized termination technologies and stable ceramic dielectrics.

Replacement Considerations

Direct substitutes must match the 1806 package dimensions, 0.12 µF capacitance, 50 VDC rating, and 3-terminal C-filter configuration. Verify compatibility of termination materials and current ratings before cross-referencing alternative manufacturers' offerings.
