1806J0500472MJTE07

Overview

The Knowles Syfer 1806J0500472MJTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material and offers a capacitance of 4.7 nF with a tolerance of ±20%. The component is rated for a DC voltage of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it utilizes flexible soft terminals to enhance board flex sensitivity. This three-terminal EMI filter configuration provides effective electromagnetic interference suppression.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Flexible soft terminal design to withstand board flex stress
• X7R dielectric material ensuring stable performance across wide temperature ranges

Applications

• Board-flex sensitive circuit designs
• High reliability electronic systems
• Electromagnetic interference filtering applications

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and termination plating specifications. Ensure that the selected variant matches the required three-terminal EMI filter topology rather than standard two-terminal configurations. Cross-reference the RoHS compliance status and environmental declarations with the latest datasheet to meet regulatory requirements for your target market.

Selection Notes

Select this component when board flex durability is critical due to its flexible terminal construction. The X7R dielectric provides suitable capacitance stability for general coupling and decoupling tasks within the specified temperature range. Consider the 1806 footprint dimensions and three-terminal layout constraints during PCB layout to ensure proper grounding and signal path integrity for optimal EMI performance.
