1812Y0500184MJTE03

Overview

The Knowles Syfer 1812Y0500184MJTE03 is a high-reliability multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a capacitance of 0.18 µF and a DC voltage rating of 50 VDC. The component utilizes a flexible terminal design to withstand board flex stress, making it suitable for sensitive applications. It operates within a temperature range of -55°C to +125°C and carries an AEC-Q200 qualification. The package size is 1812 (4532 metric), and it offers a tolerance of ±20%.

Feature Summary

• Flexible soft terminals designed to absorb mechanical stress from PCB bending
• AEC-Q200 qualified for automotive reliability standards
• X7R dielectric provides stable capacitance across wide temperature ranges

Applications

• Automotive electronics requiring board-flex resistance
• High-reliability industrial control systems
• Sensitive surface-mount assemblies subject to mechanical strain

Procurement Notes

Verify the exact suffix configuration against official Knowles Syfer documentation to ensure correct terminal type and termination material specifications. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability directly with authorized distributors. Ensure the procurement channel is authorized to guarantee component authenticity and traceability for high-reliability applications.

Selection Notes

Select this component when mechanical flexibility is critical due to PCB warping or assembly stress. The X7R dielectric balances capacitance density with temperature stability. Compare against standard rigid-terminal MLCCs if board flex is a primary concern. Ensure the 50V rating meets circuit requirements and that the 1812 footprint aligns with the design layout constraints.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in capacitors with compliant terminations. These components are engineered specifically for applications where traditional rigid MLCCs might fail due to mechanical stress during operation or assembly. The series targets industries demanding high durability and reliability under physical strain.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 50V rating, 0.18µF value, X7R dielectric, and crucially, the flexible terminal construction. Standard rigid-terminal equivalents may not provide adequate protection against board flex stress.
