1806J0500124MXTE07

Overview

The Knowles Syfer 1806J0500124MXTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features an X7R dielectric with a capacitance of 0.12 µF and a voltage rating of 50 VDC. The component utilizes a three-terminal C-filter topology within a standard 1806 (4516 metric) package. It offers a capacitance tolerance of ±20% and operates reliably across a temperature range of -55°C to +125°C. The device employs nickel barrier terminations with 100% tin plating, ensuring robust solderability and environmental compliance.

Feature Summary

• Three-terminal C-filter topology for effective common-mode noise attenuation
• X7R ceramic dielectric providing stable capacitance over wide temperature ranges
• Nickel barrier termination system with 100% tin plating for reliable surface mounting

Applications

• EMI filtering in high-density electronic assemblies
• Power supply input/output noise suppression
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the complete part number including the suffix TE07 to confirm specific packaging and termination specifications. Ensure compatibility with the target PCB footprint for 1806 three-terminal components. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Selection Notes

Select this component when space-constrained designs require superior high-frequency noise rejection compared to standard two-terminal MLCCs. The three-terminal structure provides lower parasitic inductance, making it suitable for applications demanding efficient EMI suppression without increasing board area. Consider thermal management requirements given the operating temperature limits.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, specifically engineered for surface-mount EMI filtering applications. It represents a specialized category of multilayer ceramic capacitors that integrate ground planes between terminals to enhance filtering performance while maintaining a compact form factor suitable for modern electronics.

Replacement Considerations

Direct substitutes must match the 1806 package dimensions, 50V rating, 0.12µF capacitance, and three-terminal C-filter configuration. Verify equivalent dielectric characteristics and termination materials to ensure consistent electrical performance and mechanical reliability in the final assembly.
