B32932A3104K289

Film capacitors, also called film dielectric capacitors, plastic film capacitors or film-foil capacitors, are components used for energy storage, and are characterized as having high insulation resistance and stability under varying conditions. The B32932A3104K289 is one type of film capacitor that has a many potential applications.

Composition

Film capacitors consist of two electrodes – a "metal foil" and a dielectric film. The electrodes are usually separated by thin layers of a dielectric material. The metal foils are usually made from aluminum or copper and the dielectric films are typically made from polyethylene terephthalate (PET) or polycarbonate (PC). These electrodes are clamped together and kept apart by layers of metalized paper or plastic, which act as insulation. Metalized paper or plastic can also be used as a barrier between two aluminum electrodes. When the two electrodes are connected, a charge builds up in the form of current. The current builds up in the electrode until the capacitor is fully charged.

Physical Description

The B32932A3104K289 film capacitor is a radial leaded device with a medium sized body. It measures just 10 x 20 mm, and has a voltage rating of 63V. It is a non-polarized device, meaning that the capacitor can be used in either direction. The device has an insulation resistance of more than 1000 megohms at 10V and an operating temperature range of -55°C to +105°C. It is also marked with the UL Recognition Mark.

Application Field and Working Principle

The B32932A3104K289 is typically used for safety circuits, for storing energy in applications such as pulse generators and high frequency amplifiers, and for filter or buffer circuitry. Its small size and light weight also make it suitable for applications where size is a concern.

The B32932A3104K289 operates by allowing current to flow through it while the voltage across its terminals is equal to the charge stored on the capacitor. This charge is permitted to flow in one direction, while the other direction is blocked, thus forming a closed loop allowing the charge to move through the capacitor until it reaches its desired level. The device also helps dampen the effects of power surges and provides a low-resistance path for current to bypass other components in the circuit.

In addition, the B32932A3104K289 can be used for power factor correction in AC circuits, and for buffer circuits used in motor drives, inverters, and other high power electrical circuits. The device also provides filtering, buffering, and transient suppression, and can be used to reduce the "ringing" effect of inductive loads in AC circuits.

Conclusion

The B32932A3104K289 is a film capacitor with a wide range of potential applications. This device is ideal for safety circuits, pulse generators, high frequency amplifiers, power factor correction, buffer circuits, motor drives, inverters, and other high power electrical circuits. It is small and lightweight, and is marked with the UL Recognition Mark.
