Film capacitors are versatile components that can be designed into power electronics for industries ranging from consumer and renewables to automotive, aerospace and military. These capacitors come with very specific advantages including non-polarity, a high insulation resistance, low dielectric losses and self-healing capability.
The taping information is based on the international standard IEC 60286-2. Remark valid for all taped film capacitors, axial and radial, ammo and reel: for all taped film capacitors a maximum of 3 slices per 1000 pieces is permitted. 1.1. RADIAL POTTED FILM CAPACITORS (Dimensions in mm) 1.1.1.
The polyester film is most reliable and together with PP most used of the plastic films. It can be produced in thicknesses down to 0.7 μm (0.03 mils). Its tensional stability is high and its ε r ≈ 3.2. This has facilitated manufacture of one for organic dielectrics very space-saving capacitor.
The most common dielectric materials used in the construction of plastic film capacitors are polypropylene and polyester.
Like all capacitors, metallized film capacitors incorporate metal plates separated by a dielectric. Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life.
