Film capacitors are general-purpose capacitors used in a variety of applications. The B32932A3104M289 is a type of film capacitor that has a wide range of use cases. It is a polyester film capacitor with a non-polarised radial leaded hermetically sealed aluminium case. The capacitor has a nominal capacitance of 3.9nF, a rated voltage of 630VAC, a temperature coefficient of +350ppm/°C, and a dissipation factor of 2.3mm/V.

The B32932A3104M289 is typically used in AC circuits. Due to its low ESL and ESL scattering, low voltage dissipation factor, and low temperature coefficient of capacitance, it is often used in AC filter circuits, noise suppression circuits, high-frequency circuits, decoupling circuits, and high-speed waveform sampling and decoding circuits. It is often used in residential, commercial and industrial settings, such as lighting and temperature control systems, motor control systems, audio amplifiers and speakers, and computers.

The B32932A3104M289 can also be used in DC circuits. Its high breakdown voltage and low working voltage, low voltage coefficient of capacitance and low loss factor make it ideal for use in storage circuits, energy-efficient conversion circuits, pulse circuits, and high-voltage amplitude modulation circuits. It is also commonly used in consumer electronics, home theater systems and other consumer applications.

The working principle of the B32932A3104M289 is based on the electrostatic principle. When an electric voltage is applied to the capacitor, it causes a temporary electric field between its plates. This field creates an electrical field force that stores energy as an electrostatic charge in the capacitor. This charge remains in the capacitor until the electric field is removed. The stored energy is then released as an electric current when the electric field is removed.

In summary, the B32932A3104M289 is a polyester film capacitor with a non-polarised radial leaded hermetically sealed aluminium case. It has a nominal capacitance of 3.9nF, a rated voltage of 630VAC, a temperature coefficient of +350ppm/°C, and a dissipation factor of 2.3mm/V. It is used in AC and DC circuits for power filtering, noise suppression, energy storage, and other applications. It works on the electrostatic principle, where an electric field causes a temporary electric field between its plates, which then stores energy as an electrostatic charge in the capacitor.
