YMIN new Product Series：Liquid lead type Aluminum Electrolytic Capacitor—LKD series
01 Changes in terminal device demand pose new challenges to the input side
With the development of emerging industries such as smart terminals, smart homes, security technology, and new energy (automotive electronics, energy storage, photovoltaics), the demand for high-power power supplies and energy storage equipment is increasing day by day, bringing with it new requirements and challenges for more diversified upstream and downstream products. For example, as the power of high-power power supplies and energy storage equipment on the market becomes larger and larger, the size of the whole machine needs to be designed smaller and smaller due to the user’s emphasis on product utilization and space occupancy. This contradiction is becoming increasingly serious.
High-voltage and high-capacity capacitors used for input filtering in high-power power supplies and energy storage are an indispensable part of the industry. They play a key role in reducing energy dissipation, ensuring higher power, and maintaining stable output. At present, due to the large size of liquid horn aluminum electrolytic capacitors in the mainstream market, high-power power supplies and energy storage equipment in the market cannot meet the miniaturization requirements when their overall size decreases, resulting in liquid Snap-in aluminum electrolytic capacitors facing challenges in terms of size.
02 YMIN Solution-Liquid Lead Type LKD New Series Capacitors
Small size/high pressure resistance/large capacity/long life
In order to solve the pain points and difficulties of customers in product application, give full play to product performance, take into account customer experience, and meet the market demand for high-power power supplies and small-sized energy storage equipment, YMIN actively innovates, dares to break through, and concentrates on research. The latest research and development has launched the LKD series of ultra-large capacity high-voltage aluminum electrolytic capacitors – the new series of liquid lead type LKD capacitors.
The LKD series of ultra-large capacity high-voltage aluminum electrolytic capacitors launched this time are 20% smaller in diameter and height than Snap-in products under the same voltage, capacity and specifications. The diameter can be 40% smaller while the height remains unchanged. While reducing the size, the ripple resistance is not inferior to the liquid Snap-in aluminum electrolytic capacitors of the same voltage and capacity, and can even be comparable to the Japanese standard size. In addition, the life span is more than twice that of the Snap-in capacitor! In addition, the finished products of the LKD series of ultra-large capacity high-voltage aluminum electrolytic capacitors have a high withstand voltage. The withstand voltage of the finished products of the same specifications is about 30~40V higher than that of Japanese brands.
