1806J0500274MXTE01

Overview

The Knowles Syfer 1806J0500274MXTE01 is a feed-through multilayer ceramic capacitor (MLCC) in an 1806 surface-mount package. It features a capacitance of 0.27 µF with a ±20% tolerance and a DC voltage rating of 50 VDC. Designed for high-frequency noise suppression, this component integrates a three-terminal structure to provide effective electromagnetic interference (EMI) filtering. The unit operates within a temperature range of -55°C to +125°C and includes a current rating of 300 mA.

Feature Summary

• Three-terminal feed-through architecture for enhanced EMI suppression
• High capacitance density in a compact 1806 surface-mount footprint
• Integrated current handling capability for power line applications

Applications

• Electromagnetic interference (EMI) filtering on power supply lines
• Noise suppression in high-density electronic assemblies
• Signal integrity protection in sensitive circuit interfaces

Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to confirm terminal plating and packaging variations. Ensure the selected variant matches the required current rating and thermal specifications for the target application environment. Cross-reference the full part number with authorized distributor catalogs to confirm availability and compliance status before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require superior high-frequency noise attenuation compared to standard two-terminal capacitors. The three-terminal design offers lower parasitic inductance, making it suitable for high-speed digital circuits. Evaluate the 300 mA current rating to ensure it meets the operational load requirements without exceeding thermal limits during continuous use.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor family, which specializes in integrated EMI filtering solutions. These devices combine decoupling and filtering functions into a single surface-mount element. The 1806 series provides a balance between performance and board space efficiency, catering to modern electronics that demand robust noise immunity in minimal footprints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feed-through capacitors by matching the 1806 footprint, 0.27 µF capacitance, 50 VDC rating, and 300 mA current handling capabilities.
