1206Y1000183MJTE03

Overview

The Knowles Syfer 1206Y1000183MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1206 (3216 metric) case size with a capacitance of 18 nF and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, providing stable performance across a wide temperature range from -55°C to +125°C. It offers a tolerance of ±20% and is manufactured with flexible terminations to enhance mechanical durability. This part is AEC-Q200 qualified for automotive use and complies with RoHS standards.

Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• Flexible termination technology for enhanced mechanical stress resistance
• X7R dielectric material for stable capacitance characteristics
• High-reliability construction suitable for demanding environments

Applications

• Automotive electronic circuits requiring robust capacitors
• High-reliability industrial equipment power supplies
• General-purpose filtering and decoupling in SMD/SMT assemblies

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation to ensure compliance with project quality standards. Confirm that the flexible termination variant matches the PCB layout requirements for mechanical stress relief. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering to maintain component integrity during assembly processes.

Selection Notes

Select this component when a 1206 footprint is required with a 100V rating and 18nF capacitance. The X7R dielectric provides a balance of volumetric efficiency and stability. The flexible termination option is critical for designs subject to board flexing or thermal cycling. Verify that the ±20% tolerance meets the circuit's precision requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with flexible terminations to prevent cracking under mechanical stress. The 1206Y series designation indicates the 1206 case size and X7R dielectric type. It is categorized as a Class 2 ceramic capacitor, offering higher capacitance values than Class 1 counterparts within the same physical volume.

Replacement Considerations

Direct substitutes must match the 1206 case size, 100V rating, 18nF value, X7R dielectric, and flexible termination style. Generic X7R 1206 capacitors with rigid terminations may not provide equivalent mechanical reliability in high-stress automotive or industrial applications.
