B32529C1102J289

Film capacitors, or film dielectric capacitors, are electrical components built with metal-film dielectric materials. The B32529C1102J289, which belongs to this group, is a general purpose radial-leaded metallized polypropylene film capacitor.

The fields of applications for this particular capacitor are varied and include power supplies, active filters and snubbers in a wide range of frequencies, portable equipment, and audio equipment. It is a non-polarized capacitor and is expected to endure temperatures between -40 degrees to 85 degrees Celsius.

In terms of construction, the B32529C1102J289 is composed of metallized polypropylene film with copper-clad aluminium wire and the necessary epoxy wrapping. The copper-clad aluminium wire is itself made of aluminum sealed by a thin layer of copper, encompassing most of the silver while reducing overall size and weight of the capacitor. The construction ensures moderate electrical arc suppression, allowing a long life expectancy as well as stable performance.

The working principle behind a film capacitor is fairly simple. Two alternating layers of positive and negative charges are separated only by the film dielectric. As a result, an electric field is created from the displacement of electrons, creating a form of stored electrical energy. Fundamentally, the capacitor holds charge when an electrical field is applied to the conductive plates, and its capacitance determines why much charge it can hold.

In this particular capacitor, the capacitance ranges from 1.0 nanofarad to 5.6 nanofarad, with single tolerance of ±20%. The rated voltage is 125 VAC with a working voltage up to 175 VAC, allowing it to manage high voltage input even during surges. The impedance, on the other hand, is 400 volts per microfarad at 1kHz and 550 volts per microfarad at 50 Hz, while the insulation resistance is at least 10,000 megohms.

The B32529C1102J289 can also be used in a range of industries such as telecommunications, consumer electronic devices, LED lighting and solar energy applications, amongst others. It is extremely lightweight, with low profile which makes it an ideal candidate for large-scale assembly lines.

In conclusion, the B32529C1102J289 is a general purpose radial-leaded metallized polypropylene film capacitor that features a non-polarized design for temperatures ranging -40 to 85 degree Celsius and with a storage temperature of -40 to 125 degrees Celsius. Its wide range of uses include power supplies, portable and audio equipment and other consumer electronics. Under is mechanics, the capacitor is composed of polypropylene with copper-clad aluminium wire and epoxy wrapping, while its capacitance ranges from 1.0 to 5.6 nanofarads with rated voltage of 125 and working voltage of 175 VAC, and impedance of 400 volts per microfarad to 550 volts per microfarad depending on the frequency.
