Film CapacitorsFilm capacitors, also called film dielectric capacitors, plastic film capacitors, thin film capacitors, film-foil capacitors, are a type of capacitor made up of a film of dielectric material sandwiched between two metal foils. Film capacitors offer excellent electrical characteristics over wide temperature and frequency ranges. With their low dielectric absorption, low dielectric losses and dielectric non-linearity, film capacitors are highly stable and ideal for applications that require a stable dielectric. This makes them ideal for use in filters, timing, pulse, snubber, and coupling circuits.B32912A3333K289 is a film-foil capacitor, primarily intended for use in pulse applications. This series of capacitor features an epoxy coating and flame- retardant construction. It provides a robust performance and is perfect for use in AC and DC circuits.The B32912A3333K289 has a charging voltage of max. 317V, a lead spacing of 7.5 mm, and a capacitance of 0.033μF. It has a rated dissipation factor of 0.4 and a dielectric absorption of 0.4%. Its leads have a diameter of 1 mm, and the capacitance is designed to stay invariant over a temperature range of -55 to +125°C. It can support an operating temperature range of -65 to +135°C.The B32912A3333K289 capacitor has a wide range of applications. It is primarily used for pulse wave output and ripple noise smoothening in DC-DC converters. It can also be used in other power supply products as well as for suppression of transient noise. Some of the applications include filtering, buffering, and bypassing for AC and DC circuits, and compensating of digital TV power supplies. It can also be used in noise prevention in high-speed signal lines.The working principle of the B32912A3333K289 capacitor is the same as other thin film capacitors. It works by providing a barrier between two metal plates or foils. This prevents electrical current from flowing directly between them, and instead forces it to take a longer route through the dielectric material in between. This increases the time it takes for the electrical current to pass, thus creating a relative variation in the electrical charge. In other words, it acts as a filter.The dielectric material between the two metal plates can vary, depending on the type of film capacitor used. Some capacitors may use polyethylene, polypropylene or polyester. This dielectric material has its own electrical properties that affect the performance of the device. These properties include dielectric constant (also called relative permittivity), dielectric strength, and the dissipation factor. The electrical properties of the dielectric material used will dictate the device’s performance in terms of voltage breakdown, capacitance, and Q (quality factor).The B32912A3333K289 capacitor is a thin film type with good performance characteristics. It provides a robust and reliable performance and is typically employed to provide for pulse wave applications. It is a reliable and economical solution for noise control and filtering in AC and DC circuits, and serves as an ideal choice for pulse circuit applications.
