Design and function of radial electrolytic capacitors

Radial electrolytic capacitors consist of two conductive electrodes that are separated from each other by an electrolyte. The anode is based on an aluminium foil with an oxidized layer as the dielectric, while the cathode usually consists of a conductive liquid or gel. This design enables high capacitance values in a compact size.

Thanks to their radial connection wires, they can be easily mounted on printed circuit boards and offer efficient energy storage and voltage stabilization. In switching power supplies, LED drivers and industrial control systems, they ensure reliable smoothing of direct current signals and buffer voltage fluctuations - essential for durable and powerful electronics.

Further information on radial electrolytic capacitors

In our FAQ section, we answer the most important questions about the design, functionality, areas of application and technical parameters of radial electrolytic capacitors. Our aim is to provide you with clear and practical information to help you select the right components.

What are the advantages of radial electrolytic capacitors compared to axial capacitors?

Radial electrolytic capacitors have a more compact design than axial capacitors, as their connections are led out on one side. This makes them more suitable for vertical mounting on printed circuit boards, which saves space and facilitates integration into dense electronic circuits. In addition, t...

Why are radial electrolytic capacitors particularly important for switching power supplies?

Switch-mode power supplies work with high frequencies and rapid voltage changes, which can lead to interference and voltage fluctuations. Radial electrolytic capacitors are indispensable here, as they smooth out these fluctuations and ensure a stable output voltage. Their low impedance and high capa...

Which technical parameters are decisive when selecting a radial electrolytic capacitor?

Several technical parameters play an important role in the selection of a radial electrolytic capacitor. Capacitance (µF) determines how much electrical charge the capacitor can store. Nominal voltage (V) indicates the voltage up to which the capacitor can be operated safely. ESR (equivalent series ...

How does the service life of radial electrolytic capacitors differ depending on the area of application?

The service life of radial electrolytic capacitors is strongly influenced by the operating conditions. In applications with low temperatures and moderate loads, such as in LED drivers, they can function for many years without any problems. In switching power supplies, on the other hand, they have to...

What role do radial electrolytic capacitors play in solar inverters?

Radial electrolytic capacitors are essential in solar inverters as they stabilize and smooth the DC voltage from the solar modules. They ensure that the conversion from direct current to alternating current is efficient and that voltage peaks are balanced out. As solar inverters often operate in h...
