1206J0500473MJTE03

Overview

The Knowles Syfer 1206J0500473MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 1206 (3216 metric) package with a capacitance of 0.047 µF and a rated DC voltage of 50 V. The component utilizes X7R dielectric material with a ±20% tolerance. It incorporates an integrated 50 mA fuse element to provide overcurrent protection within the signal path. The device employs a three-terminal architecture, functioning as an EMI filter while maintaining compact footprint requirements for dense circuit board layouts.

Feature Summary

• Integrates a built-in 50 mA fuse element for inherent overcurrent protection within the signal path
• Utilizes a three-terminal feed-through architecture to function as an effective EMI filter
• Employs X7R dielectric material to maintain stable capacitance characteristics across operating temperatures

Applications

• High-frequency noise suppression in sensitive electronic circuits
• EMI filtering for signal lines requiring integrated overcurrent protection
• Compact power distribution networks in space-constrained designs

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal plating and fuse rating specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1206 package dimensions. Cross-reference the part number with current datasheets to validate RoHS compliance status and lead time constraints before finalizing procurement plans.

Selection Notes

Select this component when simultaneous EMI filtering and overcurrent protection are required in a single surface-mount package. The 50 mA fuse rating dictates the maximum continuous current capacity, necessitating verification against circuit load requirements. The 1206 form factor offers a balance between capacitance density and thermal management capabilities compared to smaller packages.
