Preface
With the continuous development of USBPD3.1 fast charging technology, the market demand for output filtered solid-state capacitors is also increasing, in order to meet the needs of the market, many capacitor manufacturers at home and abroad have launched solid-state capacitor products for USB PD3.1 fast charging technology. These products not only have smaller size and higher withstand voltage capacity, but also have the characteristics of longer life and lower equivalent resistance, which can better meet the requirements of USB PD3.1 fast charging chargers.
As an important component in the USB PD3.1 fast charger, the role and performance of the solid-state filter capacitor have an important impact on the performance and stability of the entire charger. When the output voltage is low, the capacitance of the solid-state capacitor is relatively small, and with the increase of the output voltage, its capacitance will gradually increase, and the change of the capacitance of the solid-state capacitor will make the working environment of the output filter solid-state capacitor more stringent, and its parameters and performance will also change accordingly.
PD3.1 solid-state filter capacitor for fast charging
In the USBPD3.1 fast charger, the output filtered solid-state capacitor is a very important passive component. It is mainly used at the output end to filter and stabilize the output voltage to ensure the stability and reliability of the output voltage. Compared with traditional electrolytic capacitors, solid-state capacitors have the advantages of smaller size, lower equivalent resistance and higher withstand voltage capacity, so it is a good choice to add the following PD3.1 fast-charging solid-state filter capacitors to the USB PD3.1 fast charging charger.
The following rankings are in no particular order and are for reading purposes only.

After applying the rated voltage at 105°C for 2000 hours, the capacitor meets the requirements of durability test, temperature test, and shock wave test without obvious damage, and the capacitance changes ≤ 20% of the initial value. This shows that its impedance is very stable with temperature, and it is able to maintain stable performance under various temperature conditions.
H2 series
The capacitance of the H2 series capacitors is 4.7~1000μF, and under standard conditions, the ESR value of the H2 series is low, which helps to reduce energy loss and improve the efficiency of the system. This low ESR makes the H2 series suitable for a variety of application scenarios that require high efficiency and stability, such as PD3.1 chargers, system boards, graphics cards, smart TVs, etc.
In the dismantling of multiple fast charging chargers carried out by the charging head network, Hunan Shengtong H2 series solid-state filter capacitors with 100μF 35V specifications were also encountered from the 140W gallium nitride charger of Topa Technology. This Topma 140W GaN charger has a total output power of 140W, and both USB-C1 and USB-C2 ports support PD3.1 140W output, support power blind plugging, and USB-C3 and USB-A ports support 20W and 18W fast charging respectively. It supports automatic power distribution, which can meet the fast charging needs of notebooks and new and old mobile phones at the same time.
The above is the product specification of Shengtong H2 series. The H2 series is RoHS compliant and manufactured to lead-free specifications, which also meets modern environmental requirements. In terms of capacitance tolerances, the H2 series shows good performance. It has a wide range of capacitances, from 4.7~1000μF, to meet the needs of a variety of different applications. At the same time, its capacitance tolerance is also kept within a reasonable range to ensure the stability and reliability of the product. In terms of rated working voltage, the H2 series has a wide voltage range and supports 35V~100V DC. This allows the H2 series to adapt to a wide range of different power conditions, extending its service life.
