0805J0250473MXTE01

Overview

The Knowles Syfer 0805J0250473MXTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.047 µF with a voltage rating of 25 VDC and a current rating of 300 mA. The component utilizes an X7R dielectric material housed in a standard 0805 (2012 Metric) package footprint. This three-terminal configuration provides enhanced electromagnetic interference filtering capabilities compared to standard two-terminal devices.

Feature Summary

• Three-terminal feed-through architecture for superior EMI/RFI attenuation
• High current handling capability suitable for power line filtering applications
• X7R ceramic dielectric offering stable capacitance across operating temperatures

Applications

• Power supply input/output filtering
• Signal line noise suppression in communication equipment
• EMI mitigation in automotive electronic control units

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before integration. Confirm that the 300 mA current rating aligns with your circuit's operational requirements. Ensure PCB layout accommodates the three-pad footprint required for the feed-through terminal structure to maintain electrical performance.

Selection Notes

Select this component when high-frequency noise reduction is critical on lines carrying moderate DC currents. The 0805 form factor allows for compact board designs where space is constrained. Consider the X7R temperature coefficient if the application operates within wide thermal ranges, ensuring capacitance stability meets system specifications under varying environmental conditions.

Part Context

This part belongs to the Knowles Syfer MLCC series, specifically engineered for advanced filtering needs. Unlike standard capacitors, the feed-through design integrates the ground connection internally, reducing parasitic inductance. This family emphasizes reliability in harsh environments, leveraging nickel barrier terminations for robust solderability and long-term durability in industrial settings.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 25V rating, 0.047 µF value, and three-terminal feed-through topology. Verify that alternative components support the 300 mA current rating without excessive self-heating. Cross-reference impedance characteristics at target frequencies to ensure equivalent noise suppression performance.
