Further information on high-pulse film capacitors
In the following FAQ section, we answer the most frequently asked questions about high-pulse capacitors, their properties and possible applications. Find out why film capacitors are the best choice for high pulse currents, which technical features are important and what you should look out for when selecting them.
How do high-pulse capacitors work in power electronics?
High-pulse capacitors store electrical energy and release it in short, extremely powerful pulses. They usually consist of film capacitors that are specially designed for high dielectric strength and low losses. In power electronics, for example, they are used in circuits for high-voltage applications, where they act as energy storage and surge current sources. As soon as a switching operation is triggered, the capacitors discharge and emit a precise current pulse.
Typical applications include plasma generation, high-frequency technology and flash light systems. Due to their ability to deliver very high currents in an extremely short time, high-pulse capacitors are particularly suitable for applications where fast and precise energy output is required. In cooperation with Okaya Electric Industries, Rotima AG offers durable and reliable models that guarantee optimum performance even under extreme conditions.

What technical properties are important for high-pulse capacitors?
The selection of a suitable high-pulse capacitor depends on several technical factors. Particularly important are capacitance, dielectric strength, pulse load capacity and dissipation factors.
- Capacitance (µF): Determines the amount of energy stored and varies depending on the application.
- Dielectric strength (V): Indicates the voltage up to which the capacitor can be safely operated.
- Pulse load capacity (dV/dt): Crucial for fast charging and discharging cycles. High-pulse capacitors must be able to withstand extreme current peaks.
- Self-healing effect: High-quality film materials enable automatic repair of micro-damage, which extends the service life.
- ESR and ESL: A low equivalent series resistance (ESR) and a low equivalent series inductance (ESL) are essential for efficient energy transfer with minimal losses.

Where are high-pulse capacitors used?
High-pulse capacitors can be found in many high-performance applications where precise, powerful voltage pulses are required. Typical areas of application are
- Laser technology: For generating intense laser pulses, e.g. in medical or industrial laser systems.
- Medical technology: In shock wave lithotripters that use high-voltage pulses to break up kidney stones or gallstones.
- Pulsed current generators: For providing short-term high-voltage pulses for research or industry.
- Plasma and welding technology: For precise energy supply in welding or plasma processes.
- Electromagnetic shaping: For shaping metals with high-energy pulses.

What factors influence the service life of high-pulse capacitors?
The service life of a high-pulse capacitor depends on several factors. One of the most important is the electrical load, in particular the voltage level and the number of charging and discharging cycles. High-pulse capacitors are designed for extreme pulse currents, but continuous overloading can lead to material fatigue.
Another crucial aspect is the operating temperature. High temperatures can affect the material structure of the plastic film and shorten the service life. Good heat dissipation is therefore important.
External factors such as moisture, soiling or mechanical loads also influence durability. High-quality capacitors from Rotima AG, developed in cooperation with Okaya Electric Industries, are specially designed for high loads and offer a long service life with maximum reliability - even under extreme conditions.
