Film Capacitors

Film capacitors, also called metallized film capacitors, are capacitors that use a thin plastic or paper film as the dielectric layer. They are made in a wide range of values and shapes but share a few key characteristics which include low inductance, low equivalent series resistance, long life, and excellent capacitance stability with temperature and voltage. Due to their precise construction, film capacitors also have high ripple current ratings and offer good damping characteristics for radio frequency. These features can make film capacitors versatile and useful in a variety of applications.

BQ014E0683J Application Field and Working Principle

BQ014E0683J is a metallized polyester film capacitor made using standard radial lead design. The dielectric layer is composed of polyester film and the electrodes are of mineral plate, which conduct the electric charge, and contact the two ends of the polyester film. Its applications are mainly found in composite high pulse capacitors, motor running capacitors, and various electronic and electrical circuits. This capacitor has low losses and is suitable for applications where AC or cycling pulses are present.

The operation of the BQ014E0683J is based on conventional capacitor functioning. When a voltage is applied across it, a charge is induced on the film. This charge increases linearly with respect to the applied voltage creating a steady-state electric field. This electric field has a capacitance value that is proportional to the dielectric constant of the material used as the dielectric. The effective series resistance of the capacitor is a result of the conductivity of the layers of the dielectric material and contact resistors present at both ends.

The BQ014E0683J offers a wide range of features such as high ripple current ratings, low equivalent series resistance, long life, high capacitance stability with temperature and voltage, and excellent damping characteristics. It is also maintenance-free, thus eliminating the need for periodic replacement.
