Aluminum - Polymer Capacitors

Aluminum–polymer capacitors, also known as anranchors and hybrid capacitors, are ceramic or metal–ceramic multilayer and reprogrammable capacitors which contain an electro-active polymer made out of polyvinylidene fluoride (PVDF) or polypropylene (PP). These capacitors are thin-film passivated chips which feature low parasitic inductance, high capacitance values, and low equivalent series resistance (ESR). They also feature unique properties such as high frequency operation, low ESR, and robust performance in high power and high temperature applications.

187AVG035MFBJ Application Field & Working Principle

The 187AVG035MFBJ aluminum-polymer capacitor is a thin-film chip utilized in medium- to high-frequency circuit applications. This device exhibits low ESR, high capacitance and reduced self-heat dissipation. In addition, this capacitor operates at higher levels of peak currents and temperatures, making it an ideal choice for power and medium- to high-frequency applications. This device also offers high insulation resistance and low self-discharge (leakage) characteristics.

The 187AVG035MFBJ aluminum-polymer capacitor is composed of two electrodes, one dielectric and one conducting material. The device utilizes Al/PPE aluminum foil, which is a thin film composed of aluminum and polypropylene that is deposited on an etched aluminum electrode. The two electrodes are then overlaid with a two-layer dielectric of polypropylene (PPE) and PVDF-coated aluminum foil, forming a thin film capacitor.

The device\'s working principle involves the charging of the device\'s electrodes with the help of a voltage source. When a voltage source is applied to the device, electrons flow between the two electrodes, creating an electric field between them. This process charges the electrodes, which then stores the energy in the form of a potential difference (or voltage) in the device. To discharge the device, the voltage source is disconnected, and the electrons on the electrodes return to their original state.

The 187AVG035MFBJ aluminum-polymer capacitor can be used in a variety of applications such as DC servo motor drive circuits, AC transformer circuits, switching power supplies, brushless DC motor control circuits, and audio signal frequency signal modulation/demodulation circuits. This device also excels in high power and high frequency applications due to its low ESR, making it an ideal choice for medium- to high-frequency circuit needs.

Conclusion

In conclusion, the 187AVG035MFBJ aluminum-polymer capacitor is an excellent choice for medium- to high-frequency circuit applications. This device offers a variety of advantages such as low ESR, high capacitance, reduced self-heat dissipation, and high insulation resistance. Furthermore, this device is capable of operating at high peak temperatures and currents, making it an ideal choice for high power and high frequency applications. For these reasons, the 187AVG035MFBJ aluminum-polymer capacitor is a great choice for applications that require high performance and reliability.
