Capacitor axial

What are exxelia long-life axial capacitors used for?

Exxelia long-life axial capacitors operate at wide range of temperatures (-55 to +145°C) and offer high energy density and high-reliability. These capacitors are largely used into railway, renewable energies and power supply applications. Find answers to the most frequently asked questions about our products and services.

What are the different types of capacitor mounting configurations?

Capacitors are available in a variety of physical mounting configurations, including axial, radial, and surface mount (Figure 2). Figure 2: Capacitor mounting, or configuration types include axial, radial, and surface mount. Surface mount is very widely used at this time. (Image source: DigiKey)

What is an aluminum electrolytic capacitor?

An aluminum electrolytic capacitor comprises four separate layers: an aluminum foil cathode; an electrolyte-soaked paper separator; an aluminum anode which has been chemically treated to form a very thin aluminum oxide layer; and finally, another paper separator. This assemblage is then rolled and placed in a sealed metallic can.

What is a capacitor used for?

They are used in timing, for waveform creation and shaping, blocking direct current, and coupling of alternating current signals, filtering and smoothing, and of course, energy storage. Due to the wide range of uses, an abundance of capacitor types has emerged using a variety of plate materials, insulating dielectrics, and physical forms.

What are the different types of capacitors?

The values of the various model components are dependent upon the capacitor configuration and the materials selected for its construction. These capacitors use a ceramic dielectric. There are two classes of ceramic capacitors, Class 1 and Class 2. Class 1 is based on para-electric ceramics like titanium dioxide.

How are capacitors polarized?

All capacitors consist of the same basic structure, two conducting plates separated by an insulator, called the dielectric, that can be polarized with the application of an electric field (Figure 1). Capacitance is proportional to the plate area, A, and inversely proportional to the distance between the plates, d.
