1206J1000473MXTE01

Overview

The Knowles Syfer 1206J1000473MXTE01 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric with a capacitance of 47 nF and a DC voltage rating of 100 VDC. The component operates within a temperature range of -55°C to +125°C and offers a tolerance of ±20%. Housed in a standard 1206 (3216 metric) package, it utilizes a nickel barrier electrode structure with 100% tin terminations. This configuration supports high-frequency noise suppression applications requiring stable electrical performance under varying thermal conditions.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering capabilities compared to standard two-terminal designs.
• X7R dielectric material ensures stable capacitance characteristics across the specified operating temperature range.
• Nickel barrier termination system combined with 100% tin plating offers reliable solderability and corrosion resistance.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Electromagnetic interference (EMI) filtering in signal lines
• Power supply decoupling where low impedance paths are required

Procurement Notes

Verify the specific suffix E01 confirms the three-terminal feed-through construction, as standard MLCCs differ significantly. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure PCB footprint design accounts for the unique terminal layout of three-terminal capacitors to prevent mounting errors.

Selection Notes

Select this component when superior high-frequency attenuation is necessary compared to conventional capacitors. The three-terminal design allows for lower effective inductance, making it suitable for RF and high-speed digital applications. Consider the physical size constraints of the 1206 package against the required filtering performance.

Part Context

This part belongs to the Knowles Syfer line of high-reliability ceramic capacitors. The 1206J series designation indicates a 1206 case size with a 100V rating. The inclusion of 'E01' typically denotes specific construction features such as the three-terminal filter variant, distinguishing it from standard parallel plate capacitors within the same voltage and capacitance class.

Replacement Considerations

Direct replacements must match the three-terminal form factor and 1206 dimensions. Components like the 1206J1000473MDT share similar specifications but may lack the specific E01 construction details. Verify terminal compatibility and electrical ratings before substitution.
