KEMET How We Make Capacitors Video Series

How We Make Capacitors

We created our “How We Make Capacitors” video series to give you an inside look at how we create some of our most popular capacitors types at KEMET. Through this video series we’ll take you through our manufacturing plants to describe how our capacitors are produced from the factory floor to your favorite electronic devices. These videos will help you better understand our products, and the technology and process behind what it takes to make them.

Film Capacitors

Film capacitors are ubiquitous in industrial, green energy, and automotive applications. They are found in devices ranging from smart meters, wind and solar inverters, to electric vehicles. Film capacitors are often found in a box design, but all have a similar construction. Film capacitors are made with a plastic film layer as a dielectric. This layer may use polypropylene, polyester, PPS, or even a polymer impregnated paper. In this video we’ll unravel the mysteries of our film capacitors at KEMET.

Polymer KO-CAP Capacitors

When it comes to packing the most capacitance into the smallest package, no technology rivals KO-CAP capacitors. These capacitors have many applications in tablets and smart phones, automotive infotainment systems, to computers and spacecraft. Engineers have relied on technology in these capacitors for over fifty years. In this video we’ll take you through the manufacturing process of our KO-CAP polymer, starting from tantalum powder all the way through shaping the lead frames on the final product.

Aluminum Capacitors

Whether it’s industrial or automotive applications, aluminum electrolytic capacitors are ideal for DC Link and bulk energy storage functions. Our aluminum electrolytic capacitors are designed and manufactured to exacting standards. In this video we’ll take a closer look at what goes these cans and how we manufacture them.

Ceramic Capacitors

Ceramic capacitors are the most commonly used capacitor in the electronic industry. They are found in devices ranging from smart phones to internet routers to electric vehicle inverters. Ceramic capacitors come in a variety of package styles, but all have similar construction. The two most common forms of ceramic capacitors are the multi-layer chip capacitor (MLCC) and the ceramic disk capacitor. Here at KEMET we ship tens of billions of capacitors per year, many of which, are MLCCs.
