The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
The capacitor market is complex, with many product geometries, designs, properties and applications. New technologies and the demand for improved productivity levels have a high impact on the materials used for the construction of capacitors. These materials must meet the rigorous demands of the industry.
New technologies and the demand for improved productivity levels have a high impact on the materials used for the construction of capacitors. These materials must meet the rigorous demands of the industry. In addition, trends like e-mobility are driving the development of new materials that can withstand severe conditions and stresses.
We are certified according to DIN EN ISO 9001 and DIN EN ISO 14001. Film and foil capacitors are the most commonly used capacitors in the industry. Their essential differentiator is the dielectric used and its properties. Film capacitors come in capacitance ranges from as small as 5pF to as large as 100uF.
From the smallest capacitor beads to large power factor correction ones, they all have one thing in common: the capability to store energy in the form of an electrical charge producing a potential difference. The capacitor market is complex, with many product geometries, designs, properties and applications.
Ceramic capacitors use ceramics as a dielectric, stacked with metal layers. These devices are ideal for applica-tions with high voltage, high frequency, high power demands, and high temperatures, like the petroleum, automotive, avionics and other industries, and as multi-layer ceramic capacitors (MLCCs).
