1Object-affected harmful factors
If coil springs with small maximum diameter size are used to connect the capacitor chip to the circuit board, then acoustic noise is reduced, but stability in supporting the capacitor chip becomes insufficient
Solution Approach 1:
The patent changes the maximum diameter parameter of the supporting terminal from small (in prior art) to large (in this invention). Specifically, the maximum diameter size of the supporting terminal is designed to be larger than the maximum length size of the outer electrode, which provides both stable support and acoustic noise reduction without requiring multiple springs or electrode plates.
2Stability of the object's composition
If multiple coil springs and electrode plates are used to improve supporting stability, then stability in supporting the capacitor chip is improved, but the configuration becomes complicated
Solution Approach 1:
The patent merges the functions of multiple coil springs and electrode plates into a single supporting terminal. The supporting terminal integrates both the spring function (for acoustic noise reduction) and the electrode plate function (for stable support), eliminating the need for separate components and simplifying the overall configuration.
3Stability of the object's composition
If multiple coil springs and electrode plates are used to ensure stable support, then supporting stability is improved, but the mounting structure becomes more complex
Solution Approach 1:
The patent combines multiple supporting elements (coil springs and electrode plates) into a single integrated supporting terminal. This supporting terminal has a maximum diameter size larger than the outer electrode, providing stable support while maintaining a simple mounting structure that requires fewer components and assembly steps.

AI summary
Each of a supporting-terminal-equipped capacitor chip and a mounted structure thereof includes a capacitor chip and first and second supporting terminals that each have electric conductivity. A maximum diameter size of the first supporting terminal when viewed in an axial direction is larger than a maximum length size of a portion of a first outer electrode on a second main surface in a length direction. A maximum diameter size of the second supporting terminal when viewed in the axial direction is larger than a maximum length size of a portion of a second outer electrode on the second main surface in the length direction.
