The Importance of Selection of Super Capacitors

Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, are electrochemical components that store energy by polarizing electrolytes. Due to their advantages of large electric capacitance, long service time, wide working range, low cycle cost, and no environmental pollution, they are used in the field of new energy and has broad development prospects. Many companies did not choose the right ones when purchasing supercapacitors due to their lack of understanding of supercapacitors, resulting in many subsequent problems.

The wrong use of supercapacitors will lead to sparks, cracks, explosions and other phenomena in the supercapacitor during work, which will damage electrical appliances in light, and cause fire in serious cases, endangering personal and property losses.

The following is a picture of the super capacitor sent by our customer. From the picture, we can see that this part of the pin has turned black.

Disassembling the supercapacitor sent by the customer and comparing it with the supercapacitor of our company (JEC), we found that the root of the supercapacitor sent by the customer was burnt black. After communicating with the customer, our sales staff understood the reason. Sparks were produced to burn the root of the lead.

The product with black roots must not be used online again. In severe cases, a short circuit will cause a spark explosion. When testing supercapacitors, there must be special testing equipment for supercapacitors, and the test process should also be in accordance with the standard requirements. Improper testing will be dangerous. After communication with our company's engineers, the customer realized the importance of choosing the manufacturer and model, and purchase JEC supercapacitors.

Whether buying super capacitors or safety capacitors, it is very important to choose the right manufacturers and models. If you're not sure about the selection, you can always turn to a professional manufacturer for help. Dongguan Zhixu Electronic Co., Ltd. (also JYH HSU(JEC)) has engaged in the electronic component industry for many years, and our technical engineers can help you solve related problems. Don’t hesitate to contact us if you have questions or need samples.
