1206J0500471MCTE01

Overview

The Knowles Syfer 1206J0500471MCTE01 is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 470 pF with a tolerance of ±20%, rated at 50 VDC using C0G dielectric material. The component utilizes a three-terminal architecture within a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.1 mm in height. It operates reliably across a temperature range of -55°C to +125°C and supports a continuous current rating of 300 mA.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• C0G dielectric ensures stable capacitance performance with minimal variation under varying voltage and temperature conditions.
• Nickel barrier termination structure enhances solderability and mechanical robustness during surface mount assembly processes.

Applications

• High-frequency EMI filtering in sensitive analog and digital signal lines
• Power distribution network decoupling in compact electronic modules
• Noise suppression in automotive electronics requiring AEC-Q200 compliance

Procurement Notes

Verify the specific suffix 'TE01' against official Knowles Syfer documentation to confirm reel packaging specifications and terminal plating details. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Cross-reference the 300 mA current rating with system thermal requirements to prevent derating issues during operation.

Selection Notes

Select this component when high-frequency noise rejection is critical in space-constrained designs. The three-terminal design offers better isolation than standard MLCCs. Verify that the 50V DC rating meets the peak transient voltage levels of the application circuit. Consider the C0G stability if precise capacitance retention is required over wide temperature ranges.
