With the development of the times, fast charging of mobile phones and laptops has become popular, and the fast charging power of hundreds of watts has also brought higher requirements for chargers. In 2021, the USB PD3.1 fast charging standard will receive the latest upgrade, and the new USB PD3.1 fast charging standard will support a maximum voltage output of 48V, synchronously increasing the charging power to 240W. Fast charging technology continues to develop rapidly, with Anke, a leading e-commerce company in the fast charging industry, launching a full gallium nitride family 150W charger in 2022, taking the gallium nitride fast charging industry to another height.
In the research and development of chargers, capacitors are crucial. The matched capacitors play a filtering role in the charger, ensuring that the devices are not damaged due to impacts by absorbing impulse currents. At the same time, gallium nitride chargers on the market generally have a problem of high temperature rise due to their small size, and require capacitors with excellent heat resistance performance to cooperate, in order to achieve the goal of extending the service life of chargers. At present, the new generation of fast charging has the characteristics of high power, multiple interfaces, and small volume, and the requirements for internal electronic components are also increasing.
With the increasing power of fast charging, Yongming has developed and produced the KCM series of lead aluminum Electrolytic capacitor with higher withstand voltage and ultra small volume on the basis of the existing KCX series of special products for fast charging. The products cover a diameter range from 8 to 18 to meet all kinds of fast charging needs. Especially for high-speed charging products with power exceeding 120W, we provide high-voltage capacitor products with a diameter of 16-18, with a voltage range of 420V-450V, ensuring excellent charging performance and reliability.
In addition, in the case of limited volume, the KCM series, with its ultra-high capacity density and ultra-low ESR, can fully absorb EMI interference on the circuit under high-temperature, high-frequency, and high-power operating conditions, thereby improving the power conversion rate of the entire machine.
KCM has the characteristics of smaller volume, higher voltage resistance, and higher capacity density, while also taking into account performance advantages such as high temperature resistance, long life, lightning resistance, low leakage current, high-frequency low resistance, and large ripple resistance. It utilizes mature patented process technology, adopts new materials, and breaks through capacitor technology barriers to achieve consistency and reliability. Compared to industry fast charging capacitor products, under the same specifications, the Yongming KCM series is more than 20% lower in height than the industry, and the finished product has a voltage resistance of 30-40V higher. This provides favorable guarantees for the long-term stable operation of capacitors. At present, KCM series has become the standard volume Weather vane of fast charging capacitor products, leading the development of GaN USB PD fast charging capacitors.
At present, Yongming’s domestic capacitor products have been adopted by multiple brands such as Anke, Beisi, Anneng Technology, barley, Philips, Bull, Huakesheng, Black Shark, Jiletang, Jiayu, Jinxiang, Lvlian, Lenovo, Nokia, SYNCWIRE, NetEase Intelligent Manufacturing, and Xinhua, and their excellent product performance has been highly recognized by customers.
