Film capacitors, also known as film dielectric capacitors, are electronic components used to store energy and as filters, timing elements, coupling elements, and snubbers in electrical circuits. They are made from thin plastic or paper film, which is sandwiched between two metal plates, and often have a moderately high capacitance value over a wide frequency range. Film capacitors provide numerous benefits in terms of size, cost, and performance. B32022A3473M289 is a film capacitor manufactured by Nichicon, a well-known Japanese electronics manufacturer. This article will discuss the application field and working principle of this capacitor.

The B32022A3473M289 film capacitor is typically used in the power supply circuit of electronic products. It is designed to handle voltage between 250V ~ 315V and rated for up to 11.4A of current. It has an aluminum housing which ensures that the components within the capacitor stay cool event at high operating temperatures. The capacitor also features high ripple current capability and low impedance, making it suitable for a wide range of applications. For instance, it can be used in power supply circuits for computers, automotive electronics, motor controls, and home appliances.

The working principle of a film capacitor is based on the presence of two metal plates, one positive and one negative, which are separated by a thin plastic film called a dielectric. When a potential difference is applied across the plates, the positive plate accumulates positive charges while the negative plate accumulates negative charges. The positive and negative charges attract each other, creating a capacitor. The value of capacitance depends on the physical characteristics of the film dielectric and the distance between the plates.

The B32022A3473M289 film capacitor from Nichicon has a thermal impedance rating of 0.107 °C / W. This means that the capacitor is able to release heat more quickly and efficiently than conventional film capacitors, allowing for more reliable and stable operation. The capacitor also has a wide range of operating temperature tolerance from -40 °C to +105 °C, making it suitable for use in harsh environmental conditions. Furthermore, the capacitor has a high accuracy rating, with a capacitance deviation of 1% or better between ±25 and 105 °C. This ensures that the capacitor is able to deliver accurate and consistent performance. Finally, the capacitor has a long life span, with an expected lifetime of 10 years at nominal temperature, a remarkable lifetime for a film capacitor.

In conclusion, the B32022A3473M289 film capacitor from Nichicon is a reliable and highly accurate component which is typically used in the power supply circuit of electronic devices. It offers excellent performance in a wide range of temperatures, with a high tolerance of ±25 and 105 °C and a thermal impedance rating of 0.107 °C / W. Thanks to its robust construction and long lifetime, the capacitor is able to provide consistent and reliable performance for years to come.
