19 of the 20 fastest-growing chip companies came from China

According to reports, the growth rate of the chip industry in mainland China has now exceeded that of any country and region in the world. Per the latest released information, in the past year, 19 of the 20 fastest-growing chip companies came from China. 

(Global TMT, June 21, 2022) China's chip industry is growing faster than anywhere else in the world, according to data compiled by Bloomberg.In the past four quarters, 19 of the world's 20 fastest-growing chip industry companies were from mainland China. That compares with just eight in the same period last year. From a growth rate perspective, these Chinese suppliers of design software, processors and equipment that are critical to chip manufacturing are several times larger than large semiconductor companies such as TSMC or ASML. 

 Phelix Lee, an analyst at consulting firm Morningstar, said, "The biggest potential trend is that mainland China seeks self-sufficiency in supply chains driven by epidemic control. In 2021, mainland China imported chipsets worth up to $410 billion. Chip equipment makers from overseas suppliers rose 58% last year as mainland China continued to expand capacity, which in turn boosted local business. "There is no doubt that Chinese chipmakers can achieve revenue growth in the coming years through automotive, consumer electronics and other sectors," said Phelix Lee. 

 Total chip manufacturing sales in mainland China, including manufacturing and design firms, jumped 18% in 2021 to a record high of more than 1 trillion yuan ($150 billion), according to the China Semiconductor Industry Association. No wonder now many customers say the future of electronic components will be in China.


Chinese Yuan devaluation, now 6.35 per dollar! Thus, we can lower some export prices!

About UF Capacitors' CA42 Series Dipped Tantalum Capacitors

About UF Capacitors' CA42 Series Dipped Tantalum Capacitors

One of the most popular of the thru-hole style capacitors are the dipped tantalum capacitors. Resin dipped tantalum capacitors are often used in commercial and industrial applications. Some of the advantages of using tantalum as a dielectric are: They have a higher volumetric efficiency when compared to other types of capacitors.

They take up very little space on a printed circuit board. Tantalum capacitors have superior frequency characteristics over other types of capacitors. They are very reliable, with a shelf life that is regarded as unlimited. They do not wear out in production. They can function with a very wide temperature range (-55° to +125°C).

These types of capacitors are very durable. They are coated with a flame retardant resin that allows the capacitor to be effective in most kinds of environments. They feature low leakage current and impedance.

The lead spacing and form outline are very important in selecting your choice of dipped tantalum capacitor. Lead spacing is determined is offered in a few common spreads. Please visit our datasheet: http://www.topdiode.com/pdf/CA42_Dipped_Tantalum_Cap.pdf

These capacitors are made to specific case sizes. UF Capacitors' CA42 series of dipped radial tantalum capacitors in 5 case sizes.

Since a dipped radial tantalum capacitor is polarized it is important to understand how these units are marked to ensure that they are inserted properly into the circuit. We have included charts they will show you how some of the leading manufacturers mark this style of capacitor along with the most common lead forms.

Some applications where you can use a dipped tantalum capacitor are bypassing, coupling, blocking, filtering and timing in wide range of commercial, industrial and military applications. Other types of capacitors that can be used for these applications are ceramic and film capacitors. Each dielectric has advantages and disadvantages. The tantalum advantages are higher capacitance values within a given package size and stability of capacitance with applied DC voltage.

Performance Characteristics:
Capacitance range starts from 0.1uF up to 680uF.
Voltage range is from 3VDC up to 50VDC.
Tolerancee is usually 10% or 20%.
Temperature range is from -55 °C up to 125 °C.

Topdiode Declaration of Metal Conflict-Free​

Topdiode Declaration of Metal Conflict-Free

Topdiode Manufacturing is taking and will take due diligence within our supply chain to assure “DRC Conflict-Free” for the metals of gold(Au), tantalum(Ta), tungsten(W), cobalt(Co) and tin(Sn) are not derived from or sourced from mines in conflict areas of the Democratic Republic of Congo (DRC), or illegally taxed on trade routes, either of which are controlled by non-governmental military groups, or unlawful military factions. Trade routes not confirmed to be “Conflict Free” include direct exports from the DRC, as well as exports through Rwanda, Uganda, Burundi, Tanzania and Kenya (countries of whom the U.N. Security Council note are global export routes for DRC-mined minerals).
