1206Y0500473MJTE03

Overview

The Knowles Syfer 1206Y0500473MJTE03 is a surface-mount feed-through capacitor in a 1206 (3216 metric) package. It features a capacitance of 0.047 µF with a ±20% tolerance and a DC voltage rating of 50 V. The component utilizes X7R dielectric material and includes an integrated 50 mA fuse element for overcurrent protection. It operates within a temperature range of -55 °C to +125 °C and employs flexible terminal technology to enhance board reliability.

Feature Summary

• Integrates a built-in fuse element for circuit overcurrent protection
• Utilizes flexible terminal construction to reduce mechanical stress on the PCB
• Provides high-frequency noise suppression through feed-through architecture

Applications

• High-reliability electronic assemblies requiring combined filtering and fusing
• Space-constrained designs needing integrated protection components
• Applications sensitive to mechanical stress from thermal cycling

Procurement Notes

Verify the specific suffix JTE03 against official manufacturer documentation to confirm the presence of the integrated fuse element and flexible terminal specifications. Ensure the selected variant matches the required current rating and physical footprint for the target application design.

Selection Notes

Select this component when a single device must provide both EMI filtering and overcurrent protection in a compact form factor. Consider the 50 mA fuse rating and 50 VDC limit during circuit analysis. Verify that the flexible terminal characteristics align with the mechanical requirements of the printed circuit board assembly process.
