1206Y1000183MJTE07

Overview

The Knowles Syfer 1206Y1000183MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 0.018 µF with a voltage rating of 100 VDC and a tolerance of ±20%. Utilizing X7R dielectric material, this component operates within a temperature range of -55°C to +125°C. The device employs a FlexiCap termination system combined with a nickel barrier and 100% tin plating to enhance mechanical reliability. Housed in a standard 1206 (3216 metric) package, it is engineered for effective electromagnetic interference suppression in compact electronic assemblies.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency noise attenuation compared to standard two-terminal capacitors
• FlexiCap termination structure reduces stress on the ceramic body during board flexing and thermal cycling
• Nickel barrier layer prevents electrode migration and ensures long-term stability under harsh conditions

Applications

• Electromagnetic interference filtering in automotive electronics
• Noise suppression in sensitive signal lines of industrial control systems
• Power supply input/output decoupling in compact consumer devices

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm termination composition and dielectric grade. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated product lines.

Selection Notes

Select this component when superior high-frequency attenuation is required over standard MLCCs. The three-terminal design offers lower impedance paths for noise currents. Consider the FlexiCap feature if the application involves significant mechanical stress or board flexing. Verify that the 100V rating meets the circuit's peak voltage requirements.

Part Context

This part belongs to the Knowles Syfer FlexiCap series of EMI filter capacitors. These components are specifically engineered to address electromagnetic interference challenges in space-constrained environments. The series combines the electrical performance of ceramic capacitors with the mechanical robustness needed for demanding applications.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 0.018µF capacitance, and three-terminal EMI filter topology. Verify that alternative parts also feature compatible termination structures to maintain mechanical reliability.
