Abstract
A secondary battery or capacitor fitted with terminals and occupies less area on a packaging substrate. Either one of the positive and negative terminals is mounted within the outer surface of the secondary battery or capacitor. This reduces the area occupied by the secondary battery or capacitor fitted with terminals on the substrate. At least one step is formed on the terminal positioned opposite to the substrate. This prevents electrical shorting between the positive electrode can and the negative terminal.
Claims12
A secondary battery comprising:
- a terminal connected with an electrode at a side of a substrate and having a width of L that satisfies
- 0.4×R≦L≦R
- where R is the diameter of the secondary battery,
- wherein the distance M from an end of the terminal to the outer surface of the secondary battery satisfies
- 0≦M<r
- where r is the radius of the secondary battery.
A capacitor fitted with positive and negative terminals mounted to take leads, said capacitor comprising:
- a terminal connected with an electrode at a side of a substrate and having a width of L that satisfies
- 0.4×R≦L≦R
- where R is the diameter of the capacitor,
- wherein the distance M from an end of the terminal to the outer surface of the capacitor satisfies
- 0≦M<r
- where r is the radius of the capacitor.
