1206J1000470MCTE01

Overview

The Knowles Syfer 1206J1000470MCTE01 is a three-terminal EMI filter capacitor housed in a 1206 (3216 metric) surface-mount package. It features a capacitance of 47 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The device utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Key construction details include nickel barrier terminations with 100% tin plating. This component is designed for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture providing enhanced EMI filtering capabilities compared to standard two-terminal capacitors
• C0G/NP0 dielectric material ensures minimal capacitance variation over temperature and voltage changes
• Nickel barrier termination system with 100% tin plating for reliable soldering and corrosion resistance

Applications

• Electromagnetic interference (EMI) filtering in sensitive electronic circuits
• Power supply input/output noise suppression
• High-reliability industrial equipment signal conditioning

Procurement Notes

Verify the specific suffix 'E01' corresponds to the intended three-terminal EMI filter configuration rather than a standard MLCC. Confirm that the nickel barrier termination style matches your assembly process requirements. Ensure the 1206 footprint dimensions align with your PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or environmental status before finalizing procurement.

Selection Notes

Select this component when superior high-frequency noise attenuation is required compared to conventional capacitors. The three-terminal design offers lower parasitic inductance, making it suitable for high-speed digital lines. Consider the 100V rating and 47pF value against circuit impedance needs. Evaluate the thermal stability provided by the C0G dielectric for environments with significant temperature fluctuations.

Part Context

This part belongs to the Knowles Syfer E01 series of three-terminal EMI filter capacitors. These components are engineered specifically for suppressing electromagnetic interference in compact surface-mount designs. The 1206 case size provides a balance between filtering performance and board space efficiency, catering to modern miniaturized electronics.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology, 47pF capacitance, 100V rating, and 1206 footprint. Verify compatibility of termination materials and thermal characteristics. Standard two-terminal capacitors are not functionally equivalent due to differences in parasitic inductance and filtering efficacy.
