Capacitors. So many different types and technologies… but why? What’s unique about them? This blog post attempt to answer those questions about one of the most common capacitor technologies: the aluminum electrolytic capacitor.
The aluminum electrolytic capacitor is a passive component that has traditionally been used for filtering, timing networks, by-pass, coupling and other applications requiring a cost effective, volumetrically efficient and highly reliable component.
An aluminum electrolytic capacitor consists of an anode foil, a cathode foil and separator paper which are wound together and impregnated with an electrolyte. The anode foil has an aluminum oxide layer acting as the dielectric. After the thin aluminum foil (65 to 100 microns) is electrochemically etched to increase the plate’s surface area, the dielectric is produced by anodic oxidation on its surface. The cathode foil, in general, utilizes no oxidation process.
Note that due to the physical design elements and construction, not only does a capacitor have capacitance, but it also has a series resistance and inductance as well as a parallel resistance allowing the flow of current.
The capacitance of aluminum electrolytic capacitors (in microfarads) is expressed by the following equation:
C = 8.855 x 10e-6 x (ES/d)
E = Dielectric constant
S = Surface area of dielectric (cm2)
d = Thickness of the dielectric (cm)
Large capacitance can be obtained when:
- the dielectric constant is high
- the surface area is large
- the dielectric is thin
In aluminum electrolytic capacitors the dielectric constant is only 8 to 10, but the aluminum oxide dielectric layer is extremely thin (about 15 Angstroms per volt). High gain foil produced by the electrochemical etching creates a surface magnification, or gain, as much as 100 times for low voltage foil and 20 to 25 times for high voltage foil. Therefore (and this is a critical benefit of these capacitors):
An aluminum electrolytic capacitor can provide a large capacitance compared to other types of capacitors of the same volume
Nippon Chemi-Con – the parent company of United Chemi-Con – is the world’s largest manufacturer of aluminum electrolytic capacitors. NCC pioneered the development of raw material processing techniques and highly automated production systems. The product improvements of these innovations have dramatically improved circuit design flexibility and led to many new applications for aluminum electrolytic capacitors.

Medical equipment is one of the most rapidly evolving vertical markets in the electronics industry. Equipment is being made smarter, more-capable and smaller. Interestingly, one of the primary complaints with medical equipment is a very low-tech one: Audible noise. Equipment that has to drive a motor, a pump or any mechanical device requires a fair amount of power. And larger power supplies require cooling fans. Fans are the chief culprit of this noise. The market is demanding highly efficient medical power supplies with a smaller form factor, maximum output flexibility and low audible noise.
TDK Lambda has addressed these needs with their new “QM” (Quiet Modular) series of configurable AC/DC power supplies. Utilizing low speed, low audible noise fans, these devices are much quieter than any other solution on the market today.
The QM series of supports up to 18 outputs and total power levels to 1500W, allowing customers to configure exactly the power solution they need. In addition, these supplies come with medical isolation (MoPP) and safety certifications (IEC 60601-1, IEC 60950-1, and IEC 61010-1), making them ideal for medical, test, communications and broadcast equipment. Other features include:
- PMBus™ support
- Global ON/OFF
- Remote ON/OFF
- Remove sense
- -20C to +70C operating temperature
- Seven (7) year warranty
If you’d like more information on the QM series – or if you have a power supply requirement you’d like to discuss, please contact Cover 2 Sales
