Film capacitors, also known as plastic film capacitors, are a type of capacitor that use a plastic film as their dielectric. They are fabricated in either cylindrical or rectangular form in accordance with the USA standard (MIL-C-14257) or the European/IEC standard (EN130000-3). In comparison with other types of capacitors, they have a very low parasitics, which makes them suitable for application in filters, control and tuning circuits, and high frequency switching.

B32523Q1225J189 is a film capacitor designed to provide a high capacitance to voltage ratio, low loss, and a low equivalent series resistance (ESR). It is designed for use in high performance switching power supplies, automotive audio, and other related industries.

The working principle of a film capacitor is quite simple. When a voltage is applied across the two terminals of the capacitor, an electric field is generated in the dielectric material (plastic film). This electric field generates an electric dipole moment in the film, which results in a capacitive effect - storing electric energy. The amount of energy stored depends on the size of the electric dipole moment, and the strength of the electric field.

The electrical characteristics of the B32523Q1225J189 are a capacitance of 120µF, rated working voltage of 25V, and an ESR of 0.5Ω. The ESR is much lower than other types of capacitors, which makes it suitable for high-performance applications. The rated temperature range is from -55°C to 125°C, ensuring reliable operation in a wide range of operating conditions.

In addition, the B32523Q1225J189 has a very low self-inductance (ESL) of 5nH, making it suitable for high-frequency applications such as radio frequencies, switching power supplies, and automotive audio. The high capacitance rating also makes it suitable for use in filtering, control, and tuning circuits.

To conclude, the B32523Q1225J189 is an interesting film capacitor designed for high-performance applications. Its low ESR and ESL make it suitable for use in high-frequency switching power supplies, radio frequencies, and automotive audio. In addition, its high capacitance rating makes it suitable for use in filtering, control, and tuning circuits.
