Film Capacitors

Film capacitors offer better performance characteristics than tantalum, ceramic, and electrolytic capacitors, but they typically have shorter lifespans and are more expensive than those alternative types. The B25834C6686K4 is a device that belongs to the family of film capacitors. This article will discuss the application field, working principle and other details of this device.

Application Field

The B25834C6686K4 device is a wide band film capacitor that is specifically designed for RF applications. It is suitable for use in industrial, commercial, and automotive electronics, and can be used in numerous applications. These include power supplies, high-speed communications, security systems, sonar, radar, medical equipment, and energy management systems. Aside from the RF applications, the device can also be used for certain AC- or DC-blocking purposes.

Working Principle

A film capacitor is composed of two metal parasites that are separated by an insulating film layer. The metal parasites act as the two poles of the capacitor and their charges produce an electric field. When an alternating current is applied to the film capacitor, the electric field between the metal parasites varies according to the voltage. This field induces a charge and a current in the circuit in which the capacitor is connected.

The capacitance of the B25834C6686K4 device is highly stable over a wide temperature range. It features a low inductive effect due to its wide lead spacing, making it ideal for high-frequency applications. The device is very reliable and long-lasting thanks to its high-grade, premium materials. Furthermore, its terminals feature a tin-plated finish that reduces contact resistance and improves mechanical contact.

Other Features

The B25834C6686K4 device has a high operating temperature range of -55 degrees Celsius to 125 degrees Celsius. It also offers an impressive insulation resistance of over 100 megohms and voltage of 36 volts. The device is non-polarized, which makes it suitable for high-frequency applications and AC/DC power conversion.
