Introduction: What is Super capacitors ?

Super capacitors, also known as electrochemical capacitors (electric double layer capacitors short as EDLC), gold capacitors, farad capacitors.

EDLC which can hold more than million times capacitance of regular capacitors is the future green energy storage device. Depending on the capacitance, EDLC is able to be variously applied. Less than 1F grade EDLC backs up the data and maintains RTC(Real Time Clock) built in the circuit as an auxiliary power system when a power supply of the application such as mobile phones, MP3 players, and Audio, VCR, etc is stopped. 10F ~ 100F and thousands of F grade EDLC are being used in large hybrid cars, UPS,EMU, copier requiring an instant high power, EDLC is also being gradually expanded to power unit like solar, wind, and environment-friendly renewable energy resources as an essential component.

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.

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.

Due to the material shortage and increase demand of SMD 3mm Chip Ceramic Trimmer Capacitor.
Lead time for SMD 3mm Chip Ceramic Trimmer Capacitor may up to 4-36 weeks especially for the small Capacitance.

If you are looking or using this capacitor, please consider to place the order earlier to avoid the shortage in the future.
