Capacitors for Development and Series Production
From aluminum electrolytic capacitors to polymer and hybrid solutions, and film capacitors: We assist you in selecting the right capacitor for your application.
Capacitors for Professionals
Whether for power supply, filtering, DC link, or signal processing: choosing the right capacitor significantly impacts the performance, efficiency, and lifespan of an electronic assembly.
We support developers, purchasing, and product management in finding technically and economically suitable capacitors for their applications. In doing so, we consider not only capacitance and rated voltage, but also requirements for ESR, ripple current, temperature, lifespan, form factor, and reliability.
From initial component selection through samples and technical coordination to series supply, we personally and practically guide your project.

Capacitors for Automotive, Industry, and Power Electronics
Capacitors perform central tasks in almost every electronic system. They store electrical energy, smooth voltages, filter interference, and stabilize power supplies. The requirements for the components used vary accordingly.
Typical applications range from industrial electronics, power supplies, and drive technology to automotive and e-mobility, as well as inverters, renewable energies, and demanding power electronics.
Therefore, when selecting a capacitor, significantly more parameters than capacitance and rated voltage must be considered. Crucial factors can include ESR, permissible ripple current, temperature range, lifespan, package size, impedance, and dielectric strength.
Especially at high temperatures or under strong electrical loads, these properties directly affect the reliability and lifespan of the entire assembly.

Frequently Asked Questions about Capacitors
Capacitors
This depends, among other things, on capacitance, voltage, frequency, temperature range, ripple current, package size, and required lifespan. The application itself also plays a crucial role.
We help you to assess these requirements and compare suitable capacitor technologies and series.
Aluminum electrolytic capacitors enable high capacities and are available for a wide range of applications.
Hybrid capacitors combine a liquid electrolyte with a conductive polymer. This allows for, among other things, low ESR values and high ripple current capability. Which variant is better suited depends on the respective application.
ESR stands for Equivalent Series Resistance. In simple terms, it describes the internal ohmic losses of a capacitor.
A low ESR can be particularly important at high currents and switching frequencies, as it influences power loss and self-heating.
Ripple current refers to the AC component that flows through a capacitor. It leads to power loss and thus to heating of the component.
If the permissible ripple current is permanently exceeded, it can significantly reduce the service life of the capacitor. The ripple current rating is therefore an important selection criterion, especially for power supplies, DC/DC converters, and power electronics applications.
The service life depends in particular on temperature, electrical load, and ripple current. A high operating temperature accelerates the aging of an aluminum electrolytic capacitor.
For a reliable design, it is therefore important to consider not only the service life specified in the data sheet, but also the actual thermal load within the application.
For automotive applications, factors such as temperature resistance, vibration resistance, service life, and high electrical reliability are crucial.
Rubycon offers various capacitor series for automotive applications. Depending on the series and application, products with corresponding qualifications or AEC-Q200 suitability are also available.
Film capacitors are suitable for applications with high voltages, high currents, or specific demands for long-term stability and power dissipation.
Typical uses include DC link circuits, frequency converters, inverters, power supplies, and other power electronics applications.
PMLCAP stands for Polymer Multi-Layer Capacitor. These are compact, multi-layer polymer film capacitors in an SMD design.
They can be particularly interesting where small dimensions are to be combined with the characteristic properties of a film capacitor.
Yes. We support you from the technical pre-selection of suitable capacitors and coordination with Rubycon and other partners to the procurement of samples and subsequent series supply.
In doing so, we take into account the technical requirements of your application as well as availability and economic conditions.
