B25832C6156K9

Film capacitors are widely used in electrical and electronic circuit applications. These capacitors are characterized by their ability to store electrical charge and release it when an electrical potential is applied to them. The B25832C6156K9 is a type of film capacitor developed and provided by Vishay. This device is suitable for general purpose applications in which the temperature range is 125°C, and is offered in a variety of capacitance values.

B25832C6156K9 is a non-polarized film capacitor, constructed with two layers of polycarbonate film, and also in some special cases, two layers of polypropylene film as electrodes. A metal electrode is connected to the two terminals and acts as the leads of the device. An electrically insulating layer, typically composed of mica and epoxy, seals the capacitor and provides environmental protection. The operating voltage range of the B25832C6156K9 device is between 4 and 500 volts DC.

The working principle of a film capacitor is very simple. When DC voltage is applied across the terminals of the device, an electric field is produced which in turn causes the polycarbonate or polypropylene films to become charged and store energy in the form of an electric field. When the voltage is switched off, the capacitor discharges and stored energy is released. This process happens very quickly, making film capacitors more suitable for applications where high switching frequencies or high frequency pulse interactions are required.

Because of its construction, the B25832C6156K9 is known for its low ESR and high linearity, making it an ideal choice for high frequency and pulse applications. Its capacitance range is offered from 330 pF to 2.7 nF in low capacitance intervals, allowing designers to use it in applications over a wider range of frequencies. Additionally, these devices are equipped with solder contacts which help in the proper lead fixation and electrical connection.

The B25832C6156K9 film capacitor is commonly used in consumer electronics, automotive, and military applications. Thanks to its outstanding environmental isulation, it is perfect for audio signal and RF signal filtering, data transmission, and in automotive electronic applications such as EMC filters, anti-glare filters, and choke coils.
