Film Capacitors

Film capacitors are a type of capacitor or electrical component which uses thin film materials as a dielectric. They are widely used for both AC and DC applications such as capacitance, power supply bypassing, signal coupling and blocking, high data rate transmission and filtering, timing functions, and noise suppression. Film capacitors are also known as polypropylene (PP) capacitors, polyester capacitors, polystyrene capacitors, polyethylene naphthalate (PEN) capacitors, and mylar capacitors.

184223J250RAB-F Application Field and Working Principle

The 184223J250RAB-F from Murata Electronics is a surface mount polypropylene (PP), polyester (PET), and polyethylene (PE) film-dielectric capacitor in a radial leaded package. It is an X-capacitor developed for use in applications such as EMI filtering, line-frequency (50 / 60 Hz) power line filtering, and common-mode DC-blocking. The 184223J250RAB-F is a non-polar device with an operating voltage of 50 Volt DC (V DC ).

The 184223J250RAB-F has a capacitance rating of 0.0025μF and a ripple current rating of 5.04A. It is constructed with radially-arranged copper-clad aluminum electrodes containing a high dielectric constant PP, PET, or PE film deposited with a heavy sulfur-free electrolytic coating of pH-inhibited cadmium. The combination of film layers and electrodes provides a low ESR and high-ripple current rating.

The working principle of the capacitor can be broken down into three main parts: dielectric, conductive medium, and electric field. When an electric field is created between the two electrodes of the capacitor, a dielectric material is added, which has the ability to store electric charge in its molecular structure. The electric field creates an attractive force between the two electrodes and the charged ions within the dielectric material, resulting in energy being stored. When a voltage is applied to the electrodes of the capacitor, this stored energy flows from one side of the capacitor to the other, and a current is generated. This current can then be used as a source of power for various applications.

The 184223J250RAB-F is a reliable and efficient way to reduce interference and noise, and is an essential component of many circuits. It is also used to provide a stable voltage supply, to filter out high-frequency elements from an AC signal, and to protect a circuit from voltage transients and surges.
