1806J0500560MCTE01

Overview

The Knowles Syfer 1806J0500560MCTE01 is a surface-mount three-terminal EMI filter capacitor in the FlexiCap series. It features a 56 pF capacitance with ±20% tolerance and a 50 VDC rating. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1806 (4516 metric) package measuring 4.5 mm x 1.6 mm x 1.3 mm, it offers high current handling capability of 300 mA. This design provides effective electromagnetic interference suppression for sensitive electronic circuits.

Feature Summary

• Three-terminal feedthrough architecture for enhanced high-frequency noise attenuation
• C0G/NP0 dielectric material ensures minimal capacitance variation over temperature and voltage
• High surge current rating supports robust operation in demanding power environments
• Compact 1806 surface-mount footprint facilitates automated assembly and space-constrained designs

Applications

• Electromagnetic interference filtering in portable consumer electronics
• Power supply input/output decoupling in industrial control systems
• Signal line protection in automotive infotainment and sensor modules
• Noise suppression in telecommunications base station equipment

Procurement Notes

Verify that the specific ordering suffix matches the required termination plating and packaging format. Confirm compliance with RoHS directives and REACH regulations for the target market. Ensure the selected variant aligns with the intended thermal management requirements and soldering profile constraints during procurement planning.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency noise reduction. The three-terminal design outperforms standard two-terminal capacitors in EMI applications due to grounded center terminal isolation. Evaluate the 300 mA current rating against peak load conditions to prevent device failure during transient events.
