1806Y0500124MXTE07

Overview

The Knowles Syfer 1806Y0500124MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for general-purpose applications. It features a 120 nF capacitance with a ±20% tolerance and a 50 VDC voltage rating. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1806 (4516 metric) package, it employs flexible terminal technology to enhance reliability on flex-sensitive boards.

Feature Summary

• Flexible terminal construction reduces mechanical stress on the capacitor body during board flexing.
• X7R dielectric provides consistent capacitance stability over a wide operating temperature range.
• Surface-mount design facilitates automated assembly and compact circuit integration.

Applications

• Board-flex sensitive electronic assemblies
• General-purpose decoupling and filtering circuits
• Consumer electronics requiring reliable SMD components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and terminal specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the full part number with official distributor catalogs to avoid substitution errors due to minor alphanumeric differences in the suffix code.

Selection Notes

Select this component when a 1806 footprint is required with moderate capacitance and voltage ratings. The X7R dielectric offers a balance between cost and performance for non-critical timing applications. Ensure the design accounts for the DC bias characteristics typical of X7R capacitors at the selected operating voltage.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with soft or flexible terminations. This series is engineered to prevent cracking in rigid ceramic bodies caused by mechanical strain on the printed circuit board. The 1806Y prefix indicates the 1806 case size and X7R dielectric type within the manufacturer's catalog structure.

Replacement Considerations

Direct replacements must match the 1806 package, 120nF value, 50V rating, and X7R dielectric. Flexible termination variants are preferred if board flex is a concern. Verify that alternative manufacturers offer equivalent thermal and electrical stability profiles for the target application environment.

FAQ

What is the purpose of the flexible terminals in this capacitor?

The flexible terminals are designed to absorb mechanical stress from PCB bending, reducing the risk of internal cracking in the ceramic body during assembly or operation.

Is this capacitor suitable for high-frequency applications?

While X7R capacitors have inherent frequency limitations compared to C0G types, this component can be used for general decoupling where its capacitance value and package size are appropriate for the target frequency range.
