1206J1000473MXTE07

Overview

The Knowles Syfer 1206J1000473MXTE07 is a three-terminal EMI filter capacitor in a 1206 (3216 metric) surface-mount package. It features a 47 nF capacitance with ±20% tolerance and an X7R dielectric, rated for 100 VDC. The component utilizes a nickel barrier termination system with 100% tin plating to ensure reliable soldering and corrosion resistance. Designed for high-frequency noise suppression, it integrates shielding capabilities within the multilayer ceramic structure to attenuate electromagnetic interference in compact electronic assemblies.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Nickel barrier termination technology ensures robust mechanical integrity and reliable solderability during surface mount assembly processes.
• X7R dielectric material offers stable capacitance characteristics across a wide operating temperature range of -55°C to +125°C.

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in industrial control systems
• Electromagnetic interference suppression in automotive electronics

Procurement Notes

Verify the complete part number including suffixes such as MXTE07 to confirm specific termination and packaging details. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions align with moisture sensitivity level requirements to maintain component reliability during assembly.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise reduction without additional discrete filters. The 1206 footprint allows for direct replacement of larger through-hole or standard SMD capacitors where EMI performance is critical. Evaluate circuit impedance matching to ensure optimal filtering efficiency at target frequencies.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which incorporates flexible termination materials to withstand board flexing and thermal cycling. The series is engineered for high-reliability applications, including aerospace and automotive sectors, offering superior mechanical durability compared to conventional MLCCs while maintaining consistent electrical performance under stress.

Replacement Considerations

Direct substitutes include other 1206 3-terminal EMI filters from Knowles Syfer with identical voltage and capacitance ratings, such as variants with different termination finishes. Cross-brand replacements must match the 47 nF value, 100V rating, and three-terminal configuration to preserve circuit EMI filtering characteristics.
