Capacitor Array With Sealing Layers For Solid Electrolytic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid electrolytic capacitors require significant mounting area and increased costs when multiple elements are individually mounted, as they cannot be handled as individual units due to common anodes and multiple cathode terminals.
Innovation Solution
A capacitor array is developed, integrating multiple solid electrolytic capacitor elements with a sheet-like first and second sealing layer, allowing for external electrodes to be connected to the anode and cathode layers, enabling efficient integration and reduced mounting area requirements.

1Ease of operation
If multiple solid electrolytic capacitor elements are individually mounted, then each element can be handled as an individual unit, but the mounting area and mounting cost increase significantly
Solution Approach 1:
Multiple solid electrolytic capacitor elements are integrated into a single array structure where multiple capacitor elements are arranged in an array configuration with shared sealing layers. The first and second sealing layers extend across multiple elements, creating a unified assembly that functions as one integrated component rather than separate individual units, thereby reducing the total mounting area required.
2Ease of operation
If multiple solid electrolytic capacitor elements are individually mounted, then each element can be handled as an individual unit, but the mounting cost increases due to multiple mounting operations
Solution Approach 1:
Multiple solid electrolytic capacitor elements are integrated into a single array structure where multiple capacitor elements are arranged in an array configuration with shared sealing layers. The first and second sealing layers extend across multiple elements, creating a unified assembly that functions as one integrated component rather than separate individual units, thereby reducing the total mounting area required.
3Area of stationary object
If a capacitor array integrates multiple solid electrolytic capacitor elements, then the mounting area is reduced, but the structural complexity increases
Solution Approach 1:
The capacitor array is divided into multiple individual capacitor elements that are arranged in an array configuration. Each capacitor element maintains its own anode plate, porous layer, dielectric layer, and cathode layer structure, while being separated by insulating layers. This segmentation allows each element to function independently while being part of a compact integrated array, reducing the overall mounting area compared to individual mounting of separate capacitors.
Solution Approach 2:
The first and second sealing layers serve multiple functions simultaneously: they provide sealing for multiple capacitor elements, provide structural support for the array, enable electrical connections through external electrodes, and maintain the integrity of the integrated assembly. This multi-functionality reduces the need for additional separate components and simplifies the overall structure despite the integration of multiple elements.
