1806Y1000683MXTE01

Overview

The Knowles Syfer 1806Y1000683MXTE01 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for high-frequency noise suppression. It features a capacitance of 0.068 µF with a ±20% tolerance and a DC voltage rating of 100V. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) surface-mount package, it integrates a built-in ground plane structure to minimize parasitic inductance. This design facilitates effective electromagnetic interference (EMI) filtering in compact circuit layouts.

Feature Summary

• Three-terminal feed-through architecture providing integrated ground connection for superior high-frequency noise attenuation
• X7R dielectric composition offering reliable capacitance stability over a wide industrial temperature range
• Surface-mount 1806 footprint optimized for automated assembly and space-constrained board designs

Applications

• High-speed digital signal line EMI filtering
• Power supply input/output noise suppression
• RF circuit grounding and decoupling

Procurement Notes

Verify the complete part number including the suffix against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the specific distributor lot codes with the manufacturer's traceability records to guarantee authenticity and storage history integrity.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency noise reduction. The three-terminal design requires specific PCB pad layout considerations compared to standard two-terminal capacitors. Ensure the 100V DC rating exceeds the maximum circuit voltage with appropriate derating margins. Verify that the 1806 package dimensions fit within the available board real estate constraints.

Part Context

This component belongs to the Knowles Syfer FlexiCap™ or similar high-reliability MLCC series, characterized by robust construction for demanding environments. The 1806Y prefix indicates the case size and voltage class within the manufacturer's catalog. As a specialized EMI filter, it differs from general-purpose capacitors by its internal grounded electrode structure, which enhances common-mode noise suppression capabilities in sensitive electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Any replacement must match the 1806 footprint, 0.068 µF capacitance, 100V rating, and three-terminal feed-through topology. Verify electrical equivalence and mechanical compatibility before substitution.
