1206Y0500473MJTE07

Overview

The Knowles Syfer 1206Y0500473MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 4.70 nF with a tolerance of ±20%, utilizing X7R dielectric material. The component has a rated DC voltage of 50V and operates within a temperature range of -55°C to +125°C. It employs a FlexiCap/Nickel Barrier termination system housed in a standard 1206 (3216 Metric) package.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• FlexiCap termination technology incorporates nickel barrier layers to improve mechanical robustness against thermal shock and board flexing stresses.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input/output filtering for signal integrity preservation
• EMI mitigation in compact surface-mount designs

Procurement Notes

Verify the specific suffix 'MJTE07' to confirm the inclusion of the three-terminal EMI filter structure and FlexiCap termination. Standard MLCCs lack the internal shielding required for this application. Ensure the design accounts for the distinct terminal layout and current handling capabilities specified in the official datasheet.

Selection Notes

Select this component when standard capacitors fail to meet EMI attenuation requirements at high frequencies. The three-terminal design offers superior grounding paths for noise dissipation. Confirm that the 50V rating and 4.70 nF value align with the circuit's impedance matching and filtering frequency targets.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability components for harsh environments. The 1206Y prefix indicates the 1206 footprint and X7R dielectric characteristics. The Y series specifically denotes the integration of flexible termination technologies to enhance durability.

Replacement Considerations

Direct substitutes must maintain the three-terminal EMI filter topology and identical 1206 dimensions. Verify that alternative parts support the same Nickel Barrier termination style to ensure comparable mechanical reliability under thermal cycling conditions.
