1806J0500274MXTE07

Overview

The Knowles Syfer 1806J0500274MXTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 270 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The dielectric material is X7R (2R1), ensuring stable performance across a temperature range of -55°C to +125°C. The component utilizes a 1806 (4516 metric) package size with three terminals, incorporating nickel barrier terminations and 100% tin plating for reliable soldering.

Feature Summary

• Three-terminal feed-through architecture provides effective electromagnetic interference filtering in a compact surface-mount form factor.
• X7R dielectric material ensures consistent capacitance stability over the specified industrial operating temperature range.
• Nickel barrier termination structure combined with 100% tin plating offers robust solderability and corrosion resistance.

Applications

• High-frequency noise suppression in portable electronic devices
• EMI filtering for power distribution lines in automotive electronics
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the complete part number including the suffix MXTE07 to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the Mouser number 843-1806J0500274MXTE07 for accurate sourcing channels. Ensure storage conditions align with moisture sensitivity level requirements defined in the datasheet.

Selection Notes

Select this component when a 270 nF capacitance value is required within a 1806 footprint for EMI applications. The 50V rating suits low-voltage DC bus filtering scenarios. Consider the X7R characteristic for cost-sensitive designs where moderate temperature stability is acceptable compared to C0G types. Evaluate the three-terminal design benefits against standard two-terminal capacitors for superior high-frequency attenuation needs.
