1806Y0250333MJTE07

Overview

The Knowles Syfer 1806Y0250333MJTE07 is a multilayer ceramic capacitor (MLCC) in an 1806 surface-mount package. It features a capacitance of 33 nF with a ±20% tolerance and a DC voltage rating of 25 VDC. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. This component utilizes the FlexiCap technology with a nickel barrier and tin plating, designed for enhanced reliability in board-flex sensitive applications.

Feature Summary

• FlexiCap flexible terminal construction reduces stress on pads during board flexing
• Nickel barrier layer prevents tin whisker growth and enhances solderability
• X7R dielectric provides high volumetric efficiency for general-purpose decoupling

Applications

• Board-flex sensitive circuit designs
• General-purpose decoupling in SMD/SMT assemblies
• High-reliability electronic equipment requiring robust MLCCs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct termination and packaging specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as supply chain conditions may vary. Ensure the selected reel quantity matches production requirements to minimize waste.

Selection Notes

Select this component when board flex resistance is critical due to its flexible terminal design. The X7R dielectric offers a balance of capacitance density and temperature stability suitable for general applications. Consider the 1806 footprint constraints and 25V rating to ensure compatibility with the target circuit layout and voltage requirements.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with flexible terminations to mitigate mechanical stress. The series targets applications where standard rigid terminations might fail under thermal cycling or mechanical deformation. The 1806 size provides a mid-range capacitance option within this specialized family.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 25V rating, 33nF capacitance, X7R dielectric, and FlexiCap/Nickel Barrier termination structure. Verify that alternative parts offer equivalent board-flex sensitivity ratings and compatible soldering profiles.
