A.Power supply circuits
Stable DC power supplies are divided into intermittent control types (switching regulator) and continuous control types (Dropper).
Recent trends have shown an overwhelming growth in switching regulators, and so we talk mainly about switching regulators below.
The capacitors used in switching regulators are selected depending on the circuit. A forward switching regulator is shown as an example in Flg.6-1. Another type is a fly back regulator.
(1) Aluminum electrolytic capacitors for input (primary) smoothing circuits The Aluminum electrolytic capacitors for input smoothing circuits used on commercial voltages (100 V.AC, 200 V.AC) and commercial frequencies (60 Hz, 50 Hz) must have a high withstand voltage and a ripple current resistance complying with twice the commercial frequency (normally full-wave current).
These capacitors have large volumes (ground contact areas) compared to other components they are assembled with ,and so the demand for more compact capacitors, as well as power supplies, is strong. Another problem is the need for longer aluminum electrolytic capacitor lives, but products guaranteed for 5000 hours at 105℃ have recently been developed, thus realizing freedom from maintenance for 10 years.
(2) Aluminum electrolytic capacitors for output smoothing circuits The rated voltage of aluminum electrolytic capacitors used for smoothing at switching frequencies (20 k to 500 kHz) is determined by the output voltage, and they must have low impedance (low ESR) at switching frequencies. Therefore aluminum electrolytic capacitors for output smoothing are designed to have low impedance at 20 k to 500 kHz, and the recent development of a low resistance electrolyte using new materials has resulted in products with 1/3 to 1/4 the impedance of conventional products with the same volume. These low impedance products also have an extremely stable life
B. ECU for automotive
The electronization of in-vehicle control is accelerating these days. ECU (electrical control unit) which carries out in-vehicle control is asked for high reliance, a miniaturization, and high quality, and many aluminum electrolytic capacitors are used for it. A typical application example is shown below.
(1) Power train ECU (Engine、 HV-Inverter etc.)
(2) Motor control ECU(Power steering, a blower / radiator fan motor, an electric pump etc.)
(3) LED lump
(4) Airbag
In automotive application, there are mainly an object for smoothing of input and output of the power supply of ECU and an object for energy reserve.
The rated voltage of 25 to 50 V.DC is mainly used.Not only current aluminum capacitor, aluminum capacitor with conductive polymer and
electrolyte is increasing due to improve quality, performance, with standing-voltage.It contributes to the small size of ECU, and a weight saving these days.
Kingtronics Snap-in type Aluminum El-cap is workable for PCB Mounting. We can replace below brands with more competitive price & L/T support, about 3~4 weeks.

With the changing economic landscape and evolving consumer behavior, industries will continue their path of digital transformation. This means that the demand for semiconductors will increase. This prompts chipmakers and governments worldwide to work hard in closing the gap.
TSMC, the world’s leading semiconductor foundry, has pledged to invest $100 million to increase capacity over the next three years. Samsung and SK Hynix have teamed up with the South Korean government and spent $451 billion for the same venture.
Members of the European Union have their plans as well. The UK government is yet to reveal what they are precisely, but the idea is to help the local chip sector grow its capacity in their supply chains.
Both private and public sectors are determined to end the chip shortage. However, many challenges (policy making, local and international covid restrictions, etc.) need to be addressed before things get going.
Industry experts were optimistic at first, expecting the chip supply to recover by the end of 2021. Historically, demand for semiconductors declines every fourth quarter of the year, which should give chipmakers a chance to catch up.
That is not the case so far. It appears that the decrease in demand is not big enough for foundries to make a significant dent in the current imbalance.
They were forced to revise their initial opinion, and they now fear that the chip shortage could last until next year, maybe even until 2023.
We have to look at several factors that created this shortage tsunami that blindsided everyone. We have broken them down into the following: supply, demand, unfortunate events, and poor decision-making.
Surge in Demand
When Covid-19 restrictions rolled out worldwide, stay-at-home mandates were the norm to prevent the transmission and spread of the virus. Everyone shifted to work from home setups, businesses went online, and messaging applications were downloaded immediately. Consequently, demand for additional electronic gadgets skyrocketed. People upgraded their laptops, purchased new desktops, more tablets, etc., to meet the requirements of the current situation.
This bottlenecked supply chains, as retailers did not prepare for the sudden increase in demand for new requirements. Add the existing projects in their pipelines, and you have the perfect recipe for a global semiconductor disaster.
Bad Luck
Aside from facing COVID-related challenges, some of the biggest foundries in the world were hit by a series of unfortunate events that disrupted their production process even more.
On March 19, an electric overload burned down 600 square meters of the Renesas plant in Naka, one of the most prominent players in the global chip market. It destroyed 23 machines and rendered other areas in the facility temporarily unfit for use.
The plant was running to total capacity again by June, but the damage has been done.
In Taiwan, the worst drought in recent memory threatened to make the chip shortage even worse. Producing chips require tremendous amounts of water, which the drought is making impossible to do. In Texas, winter storms forced some of the country’s only chip plants to stop production.
Still, there are only a handful of big chip manufacturers globally, making the semiconductor industry more vulnerable.
Screw type Aluminum Electrolytic Capacitors can be applied to computers, communication powers, and Hi-ripple circuit of electric vehicle, electric train, general-purpose inverter, etc.
Our Screw type E-cap can replace below brands with competitive offer. We can also customize the request, too.
