Overview
The Knowles Syfer 1206Y0250393MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 39 nF with a tolerance of ±20% and a DC voltage rating of 25 VDC. Utilizing X7R dielectric material, the component operates within a temperature range of -55°C to +125°C. The device is housed in a standard 1206 (3216 metric) case size and incorporates FlexiCap technology with soft terminals to enhance mechanical durability. It is supplied in reel packaging.
Feature Summary
- Incorporates FlexiCap technology with flexible soft terminals to reduce stress on printed circuit boards.
- Features a nickel barrier structure integrated into the electrode design.
- Constructed as a three-terminal EMI filter configuration for enhanced noise suppression.
Applications
- Board-flex sensitive electronic assemblies
- High reliability circuit protection
- EMI filtering in signal lines
Procurement Notes
Verify the specific suffix 'E07' against official datasheets to confirm the three-terminal EMI filter configuration and nickel barrier construction. Ensure compatibility with automated pick-and-place equipment due to the 1206 package dimensions. Confirm that the X7R dielectric characteristics meet the thermal stability requirements of the target operating environment.
Selection Notes
Select this component when board flex resistance is critical due to its soft terminal construction. The three-terminal EMI filter topology offers superior noise attenuation compared to standard two-terminal capacitors. Verify that the 25V rating provides sufficient margin for the application's peak voltage transients while maintaining the required 39nF capacitance value.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs. The series is engineered to withstand mechanical stress during PCB assembly and operation. The 1206Y prefix indicates the 1206 case size and general product family classification within the manufacturer's portfolio.
Replacement Considerations
Direct substitutes must match the 1206 footprint, 39nF capacitance, 25V rating, and three-terminal EMI filter structure. Verify that alternative components also feature soft terminals or equivalent flex-compliant designs to maintain mechanical reliability in sensitive applications.
FAQ
What is the specific function of the nickel barrier in this component?
The nickel barrier serves as an internal electrode layer within the three-terminal EMI filter structure, contributing to the component's electrical performance and structural integrity.
How does the FlexiCap technology benefit the circuit board?
FlexiCap technology utilizes flexible soft terminals to absorb mechanical stress, thereby reducing the risk of cracking in the ceramic body and solder joints during board flexing or thermal cycling.
