Film capacitors, also known as plastic film capacitors, are divided into metallized film capacitors, polypropylene film capacitors and polyester film capacitors according to the materials used in production. They are one kind of capacitors with good frequency, temperature and volumetric characteristics. Among them, BFC237222224 belongs to metallized film capacitor.

In general, the external structure of metallized film capacitor is cylindrical with a case outside and a core on top. The core is made of polypropylene film and is covered with aluminum film metalized on one side. The metalized film capacitor is filled with aluminum or copper electrodes, and a special liquid filled in it for insulation. The bottom of the core is equipped with two copper strips as external lead electrodes. Finally, the core is sealed with plastic casing.

BFC237222224 has the characteristics of high capacitance, low loss, high insulation resistance and reliable performance in large frequency range. Its working frequency varies from KHz to GHz, and its working temperature range is -55℃ to +100℃, far exceeding the traditional capacitor. The impedance of BFC237222224 is mainly related to the self-resonant frequency, working current and working temperature.

Therefore, BFC237222224 can be widely used in the field of high frequency and high temperature, such as in a variety of electrical and electronic equipment. In many kinds of communication equipment, its excellent high frequency performance has significant advantages over traditional capacitors. For instance, its application in broadband amplifier can reduce the insertion loss of signal amplification and improve the sensitivity of signal measurement and reception. It is even used in the filter circuit of receiver to reduce the interference of the incoming external signal from the receiving end. Moreover, BFC237222224 is also used in LCDs, hard disk drives, phase-locked loops, pulse transformers and the power supply of computer.

The working principle of BFC237222224 is quite simple. When the external alternating current is input, the directional current is generated in the capacitor owing to the charge accumulation of the plates. The direction of the current is reversed every half cycle, since the charge has been accumulated on the opposite side of the capacitor plate. After each alternating current cycle, the current begins to flow in the opposite direction, forming an inductive current with changing polarity and AC current.

In summary, BFC237222224 can be widely applied in the field of high frequency and high temperature due to its excellent properties. Its working principle is that current accumulates on the capacitor plates and changes its direction after each cycle. These characteristics make it widely used in many kinds of communication equipment, high frequency amplifiers, filters, LCDs, hard disk drivers, phase-locked loops, pulse transformers and the power supply of computer.
