Overview
The Knowles Syfer 1206J0500473MXTE07 is a multilayer ceramic capacitor (MLCC) designed as a surface-mount EMI filter. It features a 1206 package size with a capacitance of 47 nF and a DC voltage rating of 50 V. The component utilizes X7R dielectric material, providing a tolerance of ±20%. It employs a three-terminal architecture with nickel barrier and 100% tin terminations to facilitate effective electromagnetic interference suppression in compact circuit layouts.
Feature Summary
- Three-terminal structure for enhanced high-frequency noise attenuation
- Nickel barrier termination system ensuring robust solderability
- X7R dielectric composition for stable performance across operating temperatures
Applications
- Electromagnetic interference filtering in electronic circuits
- Power supply line conditioning
- Signal integrity protection in sensitive digital systems
Procurement Notes
Verify the specific manufacturer part number against official Knowles Syfer documentation to confirm the three-terminal EMI filter configuration. Ensure compatibility with standard SMD/SMT assembly processes. Confirm RoHS compliance status through current datasheets. Check for any specific handling requirements related to the nickel barrier termination during reflow soldering.
Selection Notes
Select this component when space-constrained EMI filtering is required in a 1206 footprint. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Consider the X7R dielectric characteristics for applications requiring moderate temperature stability. Verify that the 50V rating meets the circuit's maximum operating voltage.
Part Context
This component belongs to the Knowles Syfer MLCC series, specifically engineered for surface-mount applications. It represents a specialized category of capacitors that integrate filtering capabilities directly into the passive component form factor. The product line focuses on reliability and mechanical robustness for modern electronics manufacturing.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official distributor catalogs or manufacturer cross-reference tools for verified alternatives.
