Something About Aluminum Electrolytic Capacitors

Electrolytic Capacitor

An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. Due to their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage (CV) product per unit volume compared to ceramic capacitors or film capacitors.

Shenmao Capacitor established in 1970 is an Electrolytic Capacitor manufacturer in designing and manufacturing of a wide range of high quality aluminum electrolytic capacitor, ceramic capacitor and chip type aluminum electrolytic capacitor. Basic of our years-experience and good standing guarantee which we build in our field, we are very glad to offer our customers perfect, suitable goods and soonest, professional service. Looking for the reliable electrolytic capacitor manufacturer, Shenmao Capacitor is your best choice.

Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor is a type of capacitor that contains just a few essential parts: aluminum foil, electrolytic paper, an aluminum oxide layer, and two terminals (a cathode and an anode). Aluminum Electrolytic Capacitors work by using the polarity between the two terminals to maintain high capacitance within the component. Uses for Aluminum Electrolytic Capacitors include energy storage and AC resistance.

We carry a wide selection of Aluminum Electrolytic Capacitor products in stock, including Bi-Polar / Non-Polar Electrolytic Capacitors, Computer Grade Electrolytic Capacitors, General Purpose Electrolytic Capacitors, Low ESR Electrolytic Capacitors, Low Impedance Electrolytic Capacitors, Low Leakage Electrolytic Capacitors and more. You can browse to search by Capacitance, Termination Style, Voltage Rating DC, Voltage Rating AC, and more to find the right Aluminum Electrolytic Capacitor for your electronic design. 

Aluminum electrolytic capacitors are the most inexpensive type of capacitor with the widest range of sizes, capacitance and voltage range as compared to other capacitor dielectric. Due to their relatively high capacitance values, aluminum electrolytics have low impedance values, higher energy density than ceramic or film capacitors, higher power density than supercapacitors and no peak current limitations. Typical applications include input and output decoupling for smoothing and filtering in AC power supplies, switched-mode power supplies and DC/DC converters. They are also used in energy storage, power factor correction and in uninterruptible power supply (UPS) systems.

The aluminum electrolytic capacitor consists of a wound element, impregnated with liquid electrolyte, connected to terminals, sealed in a can and then aged to reduce or eliminate early life failures. They have an extremely broad capacitance range and varies based on the form factor, temperature and voltage requirement. The varieties and styles include molded and can-style SMT devices, also known as V-chips; axial and radial leaded cans, snap-in terminal cans and large can screw terminals.  Capacitance values range from 0.1 μF to to 3 F with voltage ratings from 5 Vdc to 700 Vdc. They are polar by nature and have distinct positive and negative terminals aiding in efficient and correct board placement. 

Shenmao Capacitor is the premier supplier of aluminum electrolytic capacitors and is the leading authorized distributor for several best in class, world-wide manufacturers. Shenmao Capacitor works closely with these manufacturers to provide a very broad and deep product offering. Shenmao Capacitor is committed to providing not only the latest and greatest products from our suppliers, but also the legacy products our customers expect. Shenmao Capacitor’s highly trained capacitor specialists can assist you in choosing the best aluminum electrolytic capacitor for your new or current design requirement, as well as delivering to your production needs.
