0805J0500270MCTE01

Overview

The Knowles Syfer 0805J0500270MCTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 27 pF with a voltage rating of 50 VDC and a current rating of 300 mA. The component utilizes C0G (NP0) dielectric technology housed in an 0805 (2012 metric) package. It employs a three-terminal architecture with nickel barrier and 100% tin terminations, ensuring reliable soldering and structural integrity.

Feature Summary

• Three-terminal feed-through structure providing superior high-frequency EMI filtering performance compared to standard two-terminal capacitors.
• C0G (NP0) dielectric material ensures stable capacitance characteristics across varying temperature conditions and applied voltages.
• Nickel barrier termination system combined with 100% tin plating offers robust mechanical strength and compatibility with standard reflow soldering processes.

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• EMI suppression in RF modules and wireless transmission devices

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm terminal configuration and packaging type. Ensure that the selected variant matches the required current handling capabilities for the target application circuit. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components.

Selection Notes

Select this component when space constraints require an 0805 footprint but higher filtering efficiency than standard MLCCs is necessary. Consider the 300 mA current rating to ensure it meets the load requirements without thermal degradation. Evaluate the parasitic inductance benefits of the feed-through design over conventional parallel plate capacitors.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which integrates capacitor functionality within a single three-terminal package. These devices are engineered to minimize lead inductance, offering improved high-frequency response. They serve as compact alternatives to discrete filter networks in dense PCB layouts.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers' feed-through capacitors.
