0805J1000223MXTE01

Overview

The Knowles Syfer 0805J1000223MXTE01 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 0.022 µF with a DC voltage rating of 100 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package measuring 2.00 mm x 1.25 mm, it incorporates a pass-through structure with nickel barrier and 100% tin terminations. This design facilitates high-frequency noise suppression while maintaining low parasitic inductance.

Feature Summary

• Pass-through architecture enables direct signal line integration for effective EMI filtering
• X7R dielectric provides stable capacitance characteristics over wide temperature variations
• Nickel barrier and 100% tin terminations ensure reliable solderability and corrosion resistance

Applications

• High-frequency noise suppression in RF signal paths
• EMI filtering in compact electronic modules
• Power integrity management in high-speed digital circuits

Procurement Notes

Verify the specific termination finish and dielectric class against current datasheet revisions before finalizing procurement. Confirm that the 0805 footprint dimensions align precisely with the PCB layout constraints. Ensure that the 100V DC rating meets the peak voltage requirements of the target application environment without derating issues.

Selection Notes

Select this component when space-constrained designs require integrated filtering capabilities within a standard SMD footprint. The pass-through design eliminates the need for separate filter components, reducing board area. Consider the X7R temperature coefficient for applications experiencing moderate thermal fluctuations where precise capacitance stability is required alongside noise attenuation.

Part Context

This part belongs to the Knowles Syfer E01 series of feed-through capacitors. These components are engineered to replace traditional discrete filters by integrating the capacitor directly into the circuit trace. The series offers a solution for minimizing electromagnetic interference in dense PCB layouts where conventional ground-plane filtering is impractical due to space limitations.

Replacement Considerations

Consult official substitution lists for compatible feed-through MLCCs from the same manufacturer family. Verify equivalent capacitance, voltage ratings, and physical dimensions before considering alternative brands.
