PPkondensaattorit

PPkondensaattorit, also known as polypropylene film capacitors, are a type of capacitor that uses a dielectric material made of polypropylene film. This material is a thermoplastic polymer known for its excellent electrical properties, including low dielectric loss, high insulation resistance, and good thermal stability. These characteristics make PPkondensaattorit suitable for a wide range of applications.

The construction typically involves thin layers of polypropylene film metallized on one or both sides, or interleaved with a separate metal foil electrode. These layers are then wound or stacked into a cylindrical or rectangular form. The leads are attached to the electrodes to facilitate connection in a circuit.

PPkondensaattorit are popular for their reliability and performance. They exhibit very little change in capacitance over a wide temperature range and have a low dissipation factor, meaning they waste very little energy as heat. This makes them efficient in AC applications.

Common uses for PPkondensaattorit include power factor correction in industrial settings, filtering in audio equipment, resonant circuits in electronic oscillators, and as snubber circuits to protect switching components from voltage spikes. Their durability and predictable performance contribute to their widespread adoption in both consumer electronics and industrial machinery.
