1806J1000471MCTE07

Overview

The Knowles Syfer 1806J1000471MCTE07 is a three-terminal feedthrough ceramic capacitor designed for surface mount applications. It features a capacitance of 470 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across a wide operating temperature range from -55°C to +125°C. Housed in an 1806 (4516 metric) package, it incorporates FlexiCap™ technology with flexible terminals to enhance mechanical reliability during soldering and thermal cycling.

Feature Summary

• Three-terminal feedthrough architecture provides effective electromagnetic interference filtering by connecting the center terminal directly to ground via low-inductance paths.
• FlexiCap™ flexible terminal construction absorbs mechanical stress, reducing the risk of lead fracture and improving resistance to board flexing and thermal shock.
• C0G (NP0) dielectric ensures minimal capacitance variation over temperature and voltage changes, maintaining signal integrity in high-frequency circuits.

Applications

• High-frequency RF circuit decoupling and grounding
• Electromagnetic interference suppression in sensitive analog and digital systems
• Power supply input/output filtering for noise reduction

Procurement Notes

Verify the specific suffix E07 against official datasheets to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with automated pick-and-place equipment regarding terminal flexibility and package dimensions. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency noise suppression. The 1806 footprint offers a balance between current handling capacity and board space efficiency. Consider the FlexiCap™ feature if the application involves significant mechanical vibration or thermal cycling that could compromise standard rigid terminations.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series of feedthrough capacitors. These components are engineered for high-reliability environments where traditional two-terminal MLCCs may fail due to mechanical stress. The 1806J series specifically targets applications requiring robust EMI protection in compact surface-mount designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings carefully if considering alternative manufacturers, as feedthrough capacitor geometries vary significantly between suppliers.
