Polypropylene capacitors

Polypropylene and polyester capacitors

Capacitors

Capacitors are electrical components that are the basis of any electrical circuit. They are two electrically charged conductors separated by a dielectric such as paper, plastic, glass, air, or other material that is a weak conductor. A field is created between the two wires in which electrical energy can be stored. This conserved electrical energy can be used in compensating for dips in the electromagnetic field. The capacity of the stored electrical energy is measured with the unit farad.

High voltage polyester capacitors

Polyester and polypropylene capacitors contain lead, but are nevertheless used for a number of applications in various fields of electronics, characterized by their small size and the high voltage they withstand. These are some of the most popular general purpose capacitors due to their ability to withstand much higher voltages such as 800 VAC and output up to 2000 VDC.

Polypropylene capacitors for suitable for:

• Electric circuits with high voltage
• Electric circuits with precision timing
• High frequency resonant electric circuits
• In the field of sound – thanks to the polypropylene capacitors, the sound quality is improved, as well as the performance.
• In electrical energy storage circuits

Types of polyester capacitors

Polyester capacitors for suitable for:

• in electrical circuits with high peak current levels,
• in power supplies where high capacities are not required,
• in audio applications

Polyester and polypropylene capacitors have small sizes and radial leads and are intended for soldering. Their small size and resistance to high voltages makes them easy to install and functional in many applications. They are resistant to damage and ignition because they are encapsulated and coated with polyester film and plastic and epoxy resin, which is flame retardant.

Mounting

• THT - pin soldering;
• SMT - surface mount with pins;
• soldering pens;
