0805J0250471MCTE01

Overview

The Knowles Syfer 0805J0250471MCTE01 is a three-terminal feed-through capacitor designed for surface mount technology. It features a capacitance of 470 pF with a tolerance of ±20%, +80% and a DC voltage rating of 25 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 0805 (2012 metric) package, it includes a nickel barrier termination system and is rated for a current handling capacity of 300 mA.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency noise suppression compared to standard two-terminal capacitors.
• Nickel barrier termination structure enhances solderability and mechanical reliability during surface mount assembly processes.
• C0G (NP0) dielectric composition ensures minimal capacitance variation over temperature changes and applied voltage conditions.

Applications

• High-frequency EMI filtering in RF signal paths
• Power line decoupling for sensitive analog circuits
• Noise suppression in high-speed digital data lines

Procurement Notes

Verify the specific tolerance code (+20%, +80%) against circuit requirements, as this differs from standard symmetric tolerances. Confirm that the 300 mA current rating aligns with the expected load in the target application. Ensure the PCB footprint accommodates the three-pad configuration required for the 0805 feed-through form factor.

Selection Notes

Select this component when superior high-frequency attenuation is required within a compact 0805 footprint. The three-terminal design offers lower effective series inductance than standard MLCCs. Consider the specific asymmetric tolerance if precise upper-limit capacitance is critical for the filter cutoff frequency calculation.

Part Context

This part belongs to the Knowles Syfer E01 series of feed-through capacitors. These components are engineered for high-reliability applications requiring robust EMI/RFI suppression. The series integrates the capacitor element directly into the terminal structure, minimizing parasitic inductance and maximizing filtering efficiency in space-constrained designs.

Replacement Considerations

Direct substitutes must match the 470 pF value, 25 V rating, 0805 package, and three-terminal feed-through topology. Verify that alternative parts support the same current rating and termination materials to ensure compatibility with existing assembly processes.
