1206Y1000123MJTE07

Overview

The Knowles Syfer 1206Y1000123MJTE07 is a multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It features a capacitance of 12 nF with a tolerance of ±20% and a DC voltage rating of 100 V. The component utilizes X7R dielectric material and incorporates FlexiCap technology with nickel barrier end terminations. Designed as a three-terminal EMI filter, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates three-terminal architecture for enhanced electromagnetic interference filtering capabilities
• Utilizes FlexiCap flexible end termination technology to mitigate board flex stress
• Incorporates nickel barrier layers on terminations to prevent tin whisker formation

Applications

• Electromagnetic interference suppression in sensitive electronic circuits
• Applications requiring resistance to mechanical stress from board flexing
• High-reliability automotive or industrial systems utilizing AEC-Q200 qualified components

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal structure and dielectric type. Ensure compatibility with automated pick-and-place equipment due to the specific physical dimensions and weight characteristics of the FlexiCap design. Confirm supply chain authenticity through authorized distributors to guarantee component integrity.

Selection Notes

Select this component when high-frequency noise attenuation is required alongside mechanical durability. The three-terminal design offers superior filtering performance compared to standard two-terminal capacitors. Consider the FlexiCap feature for assemblies subject to thermal cycling or mechanical deformation that might fracture rigid terminations.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust MLCCs for demanding environments. The 1206Y prefix indicates the 1206 case size and general product line. The MJTE07 suffix specifies the 12 nF value, X7R dielectric, nickel barrier construction, and reel packaging format.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 12 nF capacitance, and three-terminal EMI filter topology. Verify that alternative parts also include nickel barrier terminations if tin whisker prevention is critical. Standard two-terminal capacitors are not functionally equivalent for EMI filtering applications.
