1206J1000473MJTE07

Overview

The Knowles Syfer 1206J1000473MJTE07 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 47 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 100 V and supports a continuous current of 2 A. Housed in a compact 1206 (3216 metric) package, it provides effective electromagnetic interference (EMI) suppression through its internal ground connection structure.

Feature Summary

• Three-terminal feed-through architecture providing an internal ground path for superior high-frequency noise attenuation
• X7R dielectric composition ensuring stable capacitance performance across the specified operating temperature range
• High current handling capability suitable for power line filtering applications within the rated specifications

Applications

• Electromagnetic interference (EMI) filtering on power supply input lines
• Noise suppression in high-speed digital circuit power distribution networks
• Signal integrity enhancement in communication equipment requiring low-impedance grounding

Procurement Notes

Verify the specific suffix 'T07' against the manufacturer's official datasheet to confirm tape-and-reel packaging details and terminal configuration. Ensure the selected variant matches the required 2 A current rating and 100 V DC withstand voltage for the target application environment. Cross-reference the IECQ or AEC-Q200 certification status if automotive or aerospace reliability standards are mandatory for the design.

Selection Notes

Select this component when space-constrained EMI filtering requires a ground connection directly on the substrate rather than via PCB traces. The three-terminal design offers lower parasitic inductance compared to standard two-terminal capacitors. Confirm that the 1206 footprint aligns with the PCB layout constraints and that the X7R characteristics meet the thermal stability requirements of the operational environment.

Part Context

This component belongs to the Knowles Syfer 1206J series of high-reliability MLCCs. The series encompasses various dielectric types and voltage ratings, with the J prefix indicating the 1206 case size. The specific model integrates feed-through technology to minimize loop inductance, distinguishing it from standard parallel-plate capacitors in the same family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative three-terminal feed-through capacitors by matching the 47 nF capacitance, 100 V rating, 1206 package dimensions, and 2 A current handling capabilities.
