Film capacitors are components used for a variety of applications, including signal manipulation, energy storage, filtering, and coupling. Film capacitors are often referred to as “voltage-dependent capacitors” because their capacitance is determined by an applied voltage. B32621A0472M289 is an example of such a film capacitor, and application field and working principle can be discussed in relation to this part.

Applications

One of the most common uses for film capacitors is signal manipulation. These capacitors are ideal for noise reduction, signal smoothing, and frequency response adjustment – which is why they are usually found in audio systems, computer networks, and communication equipment. Film capacitors are also used in power supplies and motor drives, where they are utilized to modulate, adjust, and smooth the flow of power.

In general, film capacitors are considered to be a reliable and cost-effective alternative to other types of capacitors. B32621A0472M289 has a wide variety of uses, including power conditioning, filtering, and energy storage. This type of capacitor is also ideal for applications that require high performance or high precision, such as medical equipment and automotive systems.

Working Principle

Film capacitors are constructed from thin plastic films that are either vacuum deposited or spun onto a thin dielectric substrate. They have a low internal inductance and high insulation resistance, which makes them ideal for applications that require high-frequency responses. When a voltage is applied, the capacitance of the capacitor is determined by the applied voltage, and the dielectric constant of the film and substrate.

B32621A0472M289 is a high-performance, high-precision film capacitor. It has an operating temperature range of -55°C to +105°C and a maximum operating voltage of 300V DC. It is constructed from polyester metallized film and has a capacitance of 4700pF. The capacitor is RoHS compliant and is rated for a maximum of 10,000 hours of continuous operation.

Conclusion

Film capacitors, such as B32621A0472M289, are widely used in a variety of applications, including signal manipulation, energy storage, filtering, and coupling. These capacitors are known for their reliability and cost-effectiveness, as well as their ability to deliver high-performance and high-precision. This type of capacitor operates in accordance with the principles of an applied voltage on the film and substrate, and a dielectric constant.
