0805J0250473MJTE07

Overview

The Knowles Syfer 0805J0250473MJTE07 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 tolerance of ±20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a compact 0805 (2012 metric) package, it integrates a central conductor to facilitate low-inductance circuit board routing.

Feature Summary

• Integrates a central conductor structure to minimize parasitic inductance for effective high-frequency filtering.
• Functions as a feed-through capacitor to suppress electromagnetic interference in dense surface-mount layouts.
• Utilizes X7R ceramic dielectric to maintain stable capacitance characteristics across the specified operating temperature range.

Applications

• High-speed digital signal line filtering
• Power supply input noise suppression
• RF circuit decoupling

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination plating and reel configuration. Ensure compatibility with standard reflow soldering profiles for 0805 packages. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when low inductance is critical for EMI suppression in space-constrained designs. The feed-through architecture offers superior performance compared to standard MLCCs at high frequencies. Evaluate thermal management requirements against the X7R dielectric limits and ensure the 25V rating exceeds peak circuit voltages.

Part Context

This component belongs to the Knowles Syfer XT series of general type multilayer ceramic capacitors. The series is engineered for reliable performance in commercial and industrial applications requiring robust surface-mount solutions. The 0805 form factor allows for automated placement on standard PCB manufacturing lines.

Replacement Considerations

Direct substitutes require matching the 0805 footprint, 25V rating, 0.047 µF capacitance, and feed-through terminal configuration. Verify that alternative components support the same X7R dielectric class and current handling capabilities to maintain circuit integrity.
