Round 4-corner Type

To make the capacitance of aluminum electrolytic capacitors larger is always required. However, if elements aluminum foil are wound around the lead terminal tightly to expand the capacitance, the risk of malfunction of capacitors will increase because of breakage of aluminum foil break of the elements.

Round 4-corner type, has smooth corners by improving the die design. By reducing the risk of breakage of foil, elements can be wound more tightly, which contributes to the capacity enlargement of aluminum electrolytic capacitors.
