Film Capacitors

Film capacitors, also known as film dielectric capacitors, polyester capacitors, box capacitors, or AC capacitors, are a type of capacitor in which a thin plastic film serves as the dielectric and metal plates are used as the two electrodes. They are widely used in applications requiring low losses, small size, and high ripple current capabilities.

B32653A1952J000 Application Field and Working Principle

The B32653A1952J000 film capacitor is designed for high performance in a wide range of applications. The capacitor structure consists of three parts: a dielectric polyester film, two metal electrodes, and two electrodes for connecting the capacitor to a circuit. The dielectric is made of polyester film and has very low losses, allowing operation at high frequencies. The metal electrodes are generally made of aluminum and are specially treated to reduce losses and increase capacitance. The two electrodes are connected to a circuit to apply voltage and form an electric field in the area around the electrodes. This electric field separates positive and negative charges within the dielectric material which creates an electrical charge on the surfaces of the electrodes. The charge separation forms an electric field that acts as a capacitor.

The B32653A1952J000 film capacitor can operate over a wide temperature range and offers high ripple current capabilities making it particularly suited for power-enhancement applications. It has a low ESL of 0.25 nH, making it ideal for applications requiring a high level of accuracy. It also features a high withstand voltage of 2500 VAC and a high insulation resistance of 500 GΩ, making it suitable for high-voltage applications. The capacitor is also RoHS compliant and UL 94 V-0 approved, making it safe for use in a variety of applications.

The B32653A1952J000 is available in three different packages: Axial, Radial, and SMD. The Axial version features two 5 mm lead wires which allow for easy mounting and connection. The Radial version is available in two lead lengths, 8.5 mm and 10 mm respectively, and allows for simple and secure connections. The SMD version can be soldered to a printed circuit board and is compact, making it ideal for space-saving applications.

The B32653A1952J000 is an ideal choice for high-performance applications such as high-frequency switching power supplies, power-protection circuits, and high-end audio amplifiers. It is also suitable for low-frequency applications such as filtering circuits for radio receivers and medical equipment.
