1206Y0500184MJTE07

Overview

The Knowles Syfer 1206Y0500184MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 0.18 µF with a tolerance of ±20% and utilizes an X7R dielectric material. The component is rated for a DC voltage of 50V and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates FlexiCap/Nickel Barrier termination technology to enhance mechanical reliability. This part is classified as a Class 2 capacitor and is suitable for applications requiring robust performance under thermal stress.

Feature Summary

• Incorporates FlexiCap/Nickel Barrier termination technology to improve resistance to board flexing and mechanical stress.
• Utilizes X7R dielectric material providing stable capacitance characteristics across a wide operating temperature range.
• Designed as a three-terminal EMI filter configuration to provide effective noise suppression in compact footprints.

Applications

• Automotive electronics systems requiring AEC-Q200 compliance
• Board-flex sensitive circuit assemblies
• EMI filtering in high-density surface mount designs

Procurement Notes

Verify the specific suffix 'MJTE07' against official Knowles Syfer documentation to confirm the exact termination style and packaging configuration. Ensure that the X7R dielectric and 50V rating align with the target application's electrical requirements. Cross-reference the FlexiCap feature if mechanical durability against PCB warping is critical. Confirm RoHS compliance status through the manufacturer's environmental declarations prior to final procurement approval.

Selection Notes

Select this component when a 1206 footprint is required but enhanced mechanical reliability is necessary due to board flex constraints. The X7R dielectric offers higher volumetric efficiency compared to C0G types, making it suitable for bulk decoupling or filtering where moderate temperature stability suffices. Consider the three-terminal structure for superior high-frequency noise attenuation compared to standard two-terminal capacitors in similar packages.

Part Context

This model belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with reinforced terminations. The 1206Y prefix indicates a 1206 case size with specific internal construction optimized for automotive and industrial environments. It represents a balance between standard capacitance values and improved mechanical resilience, addressing common failure modes associated with rigid terminations in flexible substrates.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify compatibility by matching the 1206 footprint, 50V rating, 0.18 µF value, X7R dielectric, and three-terminal EMI filter topology. Ensure any alternative component also supports the required -55°C to +125°C operating range and FlexiCap-style termination if mechanical stress mitigation is essential.
