1806Y0500473MJTE07

Overview

The Knowles Syfer 1806Y0500473MJTE07 is a surface-mount multilayer ceramic feed-through capacitor designed for high-frequency noise suppression. It features a 0.047 µF capacitance with a ±20% tolerance and a 50 VDC voltage rating. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it integrates a three-terminal structure to provide effective electromagnetic interference filtering.

Feature Summary

• Three-terminal feed-through architecture for enhanced electromagnetic interference suppression
• C0G (NP0) dielectric material providing stable capacitance characteristics over temperature variations
• Flexible terminal design compatible with standard surface-mount assembly processes

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply input/output noise reduction
• Electromagnetic compatibility (EMC) improvement in sensitive devices

Procurement Notes

Verify the specific ordering suffix against official Knowles Syfer documentation to confirm terminal configuration and packaging details. Ensure the selected variant matches the required capacitance tolerance and voltage rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and authenticity before procurement.

Selection Notes
