With the development of the times, fast charging for mobile phones and notebooks 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 usher in the latest upgrade. The new USB PD3.1 fast charging standard will support a voltage output of up to 48V, and the charging power will be simultaneously increased to 240W. Fast charging technology continues to develop rapidly. Among them, Anker, the leading e-commerce company in the fast charging industry, will launch a 150W charger for the GaN family in 2022, bringing the GaN fast charging industry to another level.
1.Fast charging Dinghaishen needle-capacitor
In the research and development of the charger, the capacitor is very important. The matched capacitor plays a filtering role in the charger, and absorbs the impact current to ensure that the device will not be damaged due to the impact. At the same time, due to the small size of GaN chargers on the market, there is generally a problem of high temperature rise, and capacitors with excellent heat resistance performance are required to cooperate, so as to achieve the goal of extending the service life of the charger. At present, the new generation of fast charging has the characteristics of high power, multiple interfaces, and small size, and the requirements for internal electronic components are also getting higher and higher.
2.Ymin's new high-voltage resistant ultra-small KCM series leads the way
With the increasing power of fast charging, Ymin has developed and produced the KCM series of leaded aluminum electrolytic capacitors with higher withstand voltage and ultra-small volume on the basis of the existing KCX series of fast charging products. The products cover the diameter range From 8 to 18 to meet various fast charging needs. Especially for high-speed charging products with a power exceeding 120W, we provide high-voltage capacitor products with a diameter of 16~18mm and a voltage range of 420V~450V to ensure excellent charging performance and reliability.
In addition, in the case of limited volume, the KCM series can fully absorb the interference of EMI to the line under the working conditions of high temperature, high frequency and high power by virtue of ultra-high capacity density and ultra-low ESR, thereby improving the power of the whole machine conversion rate.
KCM has the characteristics of smaller volume, higher withstand voltage, and higher capacity density. At the same time, it takes into account performance advantages such as high temperature resistance, long life, lightning strike resistance, low leakage current, high frequency and low resistance, and large ripple resistance. It uses mature patents Process technology, using new materials, breaking through the technical barriers of capacitance, to achieve consistency and reliability. Compared with the industry's fast-charging capacitor products, under the same specification, Ymin KCM series is more than 20% lower than the industry's height, and the finished product withstand voltage is 30~40V higher. It provides a favorable guarantee for the long-term stable operation of the capacitor. At present, the KCM series has become the standard volume vane of fast charging capacitor products, leading the development of GaN USB PD fast charging capacitors.
At present, Ymin's domestic capacitor products have been approved by Anker, Baseus, Aneng Technology, Damai, Philips, Bulls, Huakesheng, Black Shark, Ji Letang, Jiayu, Jinxiang, Lulian, Lenovo, Nokia, SYNCWIRE, Many brands such as Netease Zhizao and H3C have adopted it, and its excellent product performance has been highly recognized by customers.
