1206Y0500273MJTE03

Overview

The Knowles Syfer 1206Y0500273MJTE03 is a multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features a capacitance of 27 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and incorporates FlexiCap technology with a nickel barrier for enhanced reliability.

Feature Summary

• Integrates X2Y architecture for simultaneous common-mode and differential-mode noise suppression
• Utilizes FlexiCap technology with flexible terminals to reduce mechanical stress on the substrate
• Incorporates a nickel barrier layer to prevent electrode migration and enhance long-term stability

Applications

• High-frequency EMI filtering in sensitive electronic circuits
• Power supply input/output decoupling for noise reduction
• Signal line protection in communication equipment

Procurement Notes

Verify the specific suffix 'JTE03' against the manufacturer's official datasheet to confirm the three-terminal configuration and termination style. Ensure compatibility with PCB pad layouts designed for X2Y components, as standard two-terminal footprints are incompatible. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement.

Selection Notes

Select this component when integrated common-mode and differential-mode filtering is required within a single compact footprint. The X7R dielectric offers stable performance across a wide temperature range suitable for general industrial applications. The FlexiCap feature makes it appropriate for designs subject to board flexing or thermal cycling stress.

Part Context

This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability MLCCs. The series is characterized by its use of proprietary FlexiCap technology and nickel barriers, targeting applications where standard MLCCs may fail due to mechanical stress or electromigration issues over time.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 50V rating, 27nF capacitance, and specifically the three-terminal X2Y structure. Standard two-terminal X7R capacitors cannot replace this component functionally. Verify pinout compatibility if considering alternative manufacturers offering similar X2Y architectures.
