0805Y0250473MJTE07

Overview

The Knowles Syfer 0805Y0250473MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.047 µF with a DC voltage rating of 25V and a current rating of 1A. The component utilizes an X7R dielectric material housed in a compact 0805 (2012 Metric) package. It employs a three-terminal pad configuration to provide effective noise filtering in high-frequency circuits.

Feature Summary

• Three-terminal feed-through architecture for enhanced electromagnetic interference suppression
• Integrated current handling capability suitable for power line filtering applications
• X7R ceramic dielectric providing stable capacitance characteristics across operating temperatures

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Power supply input/output noise reduction
• Signal line protection against high-frequency disturbances

Procurement Notes

Verify the specific suffix 'MJTE07' to confirm the terminal plating and packaging format, as these identifiers define the physical delivery specifications. Ensure compatibility with automated pick-and-place equipment by confirming the reel dimensions and tape-and-reel orientation match your manufacturing line requirements before finalizing procurement orders.

Selection Notes

Select this component when board space constraints require a small 0805 footprint but higher current handling than standard MLCCs. The three-terminal design offers superior high-frequency attenuation compared to two-terminal capacitors. Verify that the 25V DC rating exceeds the maximum circuit voltage and that the 1A current rating accommodates the peak load currents without saturation or thermal issues.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which integrates passive components into a single surface-mount device. Unlike traditional multi-component filter networks, these units consolidate filtering functions into a compact form factor. This integration reduces parasitic inductance and simplifies PCB layout while maintaining robust performance in demanding environments.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 0.047 µF capacitance, 25V rating, and three-terminal feed-through topology. Verify that alternative parts support the 1A current rating and offer comparable insertion loss characteristics at target frequencies. Confirm that the replacement maintains RoHS compliance and similar thermal stability.
