Film capacitors, also known as plastic dielectric capacitors, are a type of capacitor developed in the 1940s that use a thin plastic film, such as polyester or polypropylene, as the dielectric. They are available in various shapes, sizes and voltages, and are reliable and durable, with low self-inductance, high capacitance and high capacitance to volume ratio, which makes them ideal for a wide range of applications.

The B32932A3104M000 is a polypropylene film capacitor from Epcos, and is characterized by a capacitor voltage of 500V and a capacitance of 0.01 uF. It has a maximum ripple current of 25A and a working temperature range of -55°C to 125°C. It has a small size (just 10 x 16.7 mm) and is designed to withstand very high temperatures and vibrations.

Application field

Given its size, temperature range and ripple current capabilities, the B32932A3104M000 is a great choice for a variety of applications. It is commonly used as a bypass capacitor in power supplies, inverters and amplifiers, as well as in AC, DC and converter applications. It is also suitable for automotive applications, such as generator and starter motor control systems, where its temperature and vibration resistance is especially beneficial.

Working Principle

The working principle of a film capacitor is similar to that of any other capacitor. It consists of two electrical conductors (plates) separated by a dielectric material, in this case polypropylene film. When a voltage is applied across the two plates, free electrons are pushed from one plate to the other, generating an electrical field. This electric field stores energy in the form of an electrostatic charge. When the applied voltage is removed, the charge remains, creating a current flow across the two plates. This flow of electrons is what gives a capacitor its ability to store and release energy.

The amount of energy stored in a film capacitor (and other types of capacitors) is governed by three basic parameters: capacitance, voltage and frequency. Capacitance is determined by the size and shape of the plates and the type of dielectric material used. Increasing the capacitance will increase the amount of charge stored on the capacitor. The voltage is limited by the dielectric material and the maximum recommended working voltage. Finally, the frequency of the circuit will determine how often the capacitor charges and discharges.

The B32932A3104M000 is a reliable and durable film capacitor that is well-suited for a variety of applications. Its small size, temperature and vibration resistance make it an ideal choice for automotive, inverter and amplifier applications. When paired with the proper voltage and frequency, it can provide effective energy storage and improved performance for these applications.
