SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR MANUFACTURING SOLID ELECTROLYTIC CAPACITOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240347279 titled 'SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR MANUFACTURING SOLID ELECTROLYTIC CAPACITOR
The abstract of this patent application describes a solid electrolytic capacitor with multiple capacitor elements stacked on top of each other, each having an anode portion and a cathode portion. The capacitor includes an anode lead terminal connected to at least one anode portion, and three or more joining portions that connect the stacked anode portions together. The joining portions are designed to reduce variation in equivalent series resistance (ESR).
- The solid electrolytic capacitor has multiple capacitor elements stacked vertically.
- Each capacitor element consists of an anode portion and a cathode portion.
- An anode lead terminal is connected to at least one anode portion for electrical connection.
- Three or more joining portions connect and electrically link the stacked anode portions.
- The joining portions are strategically designed to minimize ESR variation.
Potential Applications: - Electronic devices - Power supply units - Automotive electronics
Problems Solved: - Reduced variation in ESR - Improved performance and reliability of capacitors
Benefits: - Enhanced stability and consistency in capacitor performance - Increased efficiency in electronic devices - Extended lifespan of capacitors
Commercial Applications: Title: Advanced Solid Electrolytic Capacitor Technology for Enhanced Performance This technology can be utilized in various industries such as consumer electronics, telecommunications, automotive, and aerospace for improved capacitor performance and reliability.
Questions about Solid Electrolytic Capacitors: 1. How does the design of the joining portions contribute to reducing ESR variation? 2. What are the key advantages of using solid electrolytic capacitors over other types of capacitors?
Original Abstract Submitted
a solid electrolytic capacitor disclosed herein includes: a plurality of capacitor elements stacked on top of each other, each capacitor element having an anode portion and a cathode portion ; an anode lead terminal electrically connected to at least one of the anode portions ; and three or more joining portions joining and electrically connecting the stacked anode portions together. the stacked anode portions have a first surface and a second surface that are located outermost on one side and the other side, respectively, in the stacking direction. the three or more joining portions include a first joining portion having a first area on the first surface and a second joining portion having a second area smaller than the first area on the first surface . thus, variation in esr can be reduced.
