1206J2000473MXTE01

Overview

The Knowles Syfer 1206J2000473MXTE01 is a three-terminal surface-mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features a capacitance of 0.047 µF with a ±20% tolerance and an X7R dielectric material. The component is rated for a DC voltage of 200V and supports a continuous current of 300 mA. It operates within a temperature range of -55°C to +125°C. The device utilizes a nickel barrier termination system with 100% tin plating, designed for high-frequency noise suppression in compact electronic assemblies.

Feature Summary

• Three-terminal feedthrough architecture provides effective electromagnetic interference filtering
• X7R ceramic dielectric ensures stable capacitance performance across the operating temperature range
• Nickel barrier termination with 100% tin plating offers reliable solderability and corrosion resistance

Applications

• High-frequency noise suppression in portable electronic devices
• EMI filtering in automotive infotainment and control modules
• Signal integrity protection in industrial communication interfaces

Procurement Notes

Verify the specific suffix MXTE01 against official Knowles Syfer documentation to confirm termination and packaging details. Ensure compatibility with standard reflow soldering profiles for 1206 SMD components. Confirm RoHS compliance status through the manufacturer's environmental declaration before integration into regulated products.

Selection Notes

Select this component when a 200V rating and 0.047 µF capacitance are required in a 1206 footprint. The X7R dielectric is suitable for general-purpose applications where moderate temperature stability is sufficient. Consider the 300 mA current rating for power line filtering or signal line decoupling needs in space-constrained designs.

Part Context

This part belongs to the Knowles Syfer 1206J series of three-terminal EMI filter capacitors. These components are engineered to replace traditional two-terminal capacitors by providing superior high-frequency attenuation. The series is widely used in consumer electronics and automotive sectors for its compact size and effective noise reduction capabilities.

Replacement Considerations

Direct substitutes include other 1206 three-terminal EMI filters with matching 200V ratings and 0.047 µF capacitance. Verify that alternative parts maintain similar insertion loss characteristics and physical dimensions to ensure board compatibility.
