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, they usually offer a higher capacitance density for the same size, which makes them particularly attractive for applications with limited space. They also have lower equivalent series resistances (ESR), which means that they compensate for voltage fluctuations more efficiently and generate less heat. Axial capacitors, on the other hand, tend to be used where horizontal mounting is required or where mechanical loads need to be evenly distributed. In industrial control systems, switching power supplies or LED drivers, radial electrolytic capacitors are often the preferred choice as they offer a higher packing density and better electrical properties.

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 capacitance enable efficient energy buffering, allowing them to absorb voltage peaks and protect sensitive electronic components.
They play a particularly important role in high-frequency applications, such as in industrial power supplies or communication devices, as they can also cope with high ripple currents. They are also able to withstand temperature fluctuations and mechanical stress, which significantly improves the reliability of switching power supplies.

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 resistance) influences the efficiency of voltage stabilization - a low ESR is particularly advantageous for high-frequency applications.
Ripple current resistance shows how much alternating current the capacitor can withstand without overheating. Temperature range indicates the ambient temperatures at which the capacitor functions reliably - standard models can withstand up to 85°C, while high-performance types can withstand up to 125°C or more. Service life (hours) is particularly important for industrial applications, as high-quality models can reach up to 10,000 hours at 105°C. The correct selection of these parameters ensures a long service life and reliable performance.

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 withstand high ripple currents and thermal loads, which reduces their service life. In industrial control systems or solar inverters, particularly durable variants are required that can withstand high temperatures and many years of continuous operation.
High-quality models achieve up to 10,000 hours at 105°C, which is made possible by high-quality materials and optimized manufacturing processes such as those offered by Hongda Capacitors. A longer service life can be further improved by the use of heat sinks or optimized placement on the circuit board. It is important to select capacitors with a sufficient safety margin in terms of voltage and temperature.

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 hot environments, the capacitors used must be particularly temperature-resistant and have a long service life. High-quality capacitors with low impedance and high ripple current resistance minimize power losses and ensure a stable power supply. Especially in grid-connected or stand-alone systems, the reliability of these components is crucial in order to maximize energy efficiency.
Thanks to our close cooperation with Hongda Capacitors, we offer radial electrolytic capacitors that have been specially developed for demanding applications such as solar inverters and meet the high requirements of renewable energy technology.
