1806Y0250124MXTE07

Overview

The Knowles Syfer 1806Y0250124MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) featuring a 120 nF capacitance with ±20% tolerance. It utilizes X7R dielectric material and supports a DC voltage rating of 25 VDC. The component measures 1806 (4520 metric) in size, specifically 4.50 mm in length and 1.60 mm in width. It incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical reliability.

Feature Summary

• FlexiCap flexible end termination design reduces stress on the capacitor body
• Nickel barrier layer prevents electrode migration and solder joint cracking
• X7R temperature stable ceramic dielectric for consistent performance

Applications

• Board-flex sensitive circuit designs
• General purpose decoupling applications
• High-reliability electronic assemblies

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm terminal composition and packaging format. Ensure the selected variant matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the full part number to distinguish between standard and specialized termination options.

Selection Notes

Select this component when board flex or thermal cycling induces mechanical stress on rigid MLCCs. The FlexiCap structure accommodates substrate movement better than standard terminations. Verify that the 1806 footprint and 25V rating align with the target circuit requirements and available PCB space constraints.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed to address reliability issues in surface-mount applications. The series combines standard ceramic capacitor functionality with enhanced mechanical durability through specialized flexible end terminations suitable for demanding environments.

Replacement Considerations

Direct substitutes within the same series include variants with different capacitance values or voltage ratings but identical 1806 dimensions and FlexiCap features. Verify pin compatibility and electrical specifications before substitution.
