To ensure proper operation, it is important to understand its working principles and applications.

Introduction to Film Capacitors / B25834D2475K4

The B25834D2475K4 from CONRACO Components is a versatile film capacitor specialized for RF communication. It is known for its small size but high capacity for storing electrical charge. This design combines the capacitors design principles with the benefits of modern organic polymers films to offer higher capacitance values. The bodies of these capacitor are made of rugged and non-conductive plastic materials. They have low industry standards, excellent noise immunity, and the ability to perform in extreme temperatures ranging from -45°C to +105°C ( -49°F to +221°F). These capacitors provide high rust-proofing, creepage, and flashover characteristics.

Application Field of B25834D2475K4

The B25834D2475K4 is primarily used as part of RF communication systems. Its small size allows for the implementation of multiple instances in highly congested RF communication systems. As such, these capacitors are often used in filter networks, signal line matching, amplification, power supplies, timing operations, and high-voltage clamping circuits. The capacitor provides low industry standards for matching components in wideband frequencies. They are also used in sensing and control circuits due to the high capacitance densities of these components.

Additionally, these film capacitors are used as ancillary components for de-icing, anti-corrosion, and EMI/RFI referencing purposes. Due to their small size and compact form factor, they can be conveniently installed in other electronic equipment to minimize maintenance costs.

Working Principle

The B25834D2475K4 operates on the principle of a classical capacitor. A capacitor is a two-terminal electronic component which stores electrical charges. A classical capacitor creates a potential difference between two conductive surfaces by holding a given amount of electrons on one surface and allowing electrons to flow onto the other surface. The stored charge creates a potential difference equivalent to the voltage applied to the capacitor. When a current is passed, the electrons move from one surface to the other, transferring the charge. The capacitance of the capacitor is determined by the ratio of the charges stored and the voltage applied.

The B25834D2475K4 is a film capacitor which uses the organic polymers films as its dielectric material. These films provide higher capacitance values than regular paper or ceramic dielectrics. The films resist the electric field, creating a small potential difference between two opposite surfaces. This potential difference is referred to as the capacitance of the capacitor, and is dependent on the area of the dielectric and the permittivity of the material. The permittivity or dielectric constant is determined by the material that composes the material. In the B25834D2475K4, this is organic polymers films.
