Aluminum Electrolytic Capacitors are widely used in a variety of applications, such as power supplies, medical electronics, automotive electronics, communications, and many other industrial applications.B43457A0478M003, is an Aluminum Electrolytic Capacitor specifically developed for such applications. This capacitor is manufactured according to the highest industry and international standards and is designed to deliver excellent performance in a wide range of applications.

B43457A0478M003 is a non-polarized aluminum electrolytic capacitor with a nominal capacitance of 0.47μF (470nF). It is constructed with a MnO2 (manganese dioxide) dielectric, a conductive medium of ethylene-propylene rubber filled with a combination of liquid electrolyte and gelled electrolyte and two aluminum foil electrodes. Its maximum allowed voltage is 6.3 volts with a permissible ripple current of 12 mA. The capacitor has two leads (due to its non-polarity) that are securely connected to the outer casing by epoxy resin. It also has a flame retardant rating of UL 94 V-0, a moisture-resistant rating of 0.5ppm, and a temperature coefficient of -30% to +85%.

B43457A0478M003 is mainly used in high-frequency circuits, where stability of capacitance is paramount. Its capacitance does not vary significantly with variations in temperature and frequency. This feature is especially beneficial for applications in switching power supplies, miniaturized receivers, harmonic filter circuits, clock circuits, and multi-input output (MIO) circuits. In addition, B43457A0478M003 is also used at engine or engine components for suppression of power current surges or fluctuations, usually employed in automotive electronics.

The working principle of B43457A0478M003 is quite simple and is based on the chemical phenomenon of electrolysis. An electrolyte solution is injected between two identical metal plates that act as the capacitor’s plates. When current is applied, the positive charge of the electrolyte molecules migrates to the negative metal plate of the capacitor, while the negative charge of the electrolyte migrates to the positive metal plate. The electrical field that builds up between the plates is what stores the energy. When the current is reversed, the electrical field between the plates reverses as well, thus allowing the capacitor to discharge its stored energy.

B43457A0478M003 is a reliable and high-performance aluminum electrolytic capacitor for a variety of applications. Its non-polarity makes it much easier to install and use than other polarized electrolytic capacitors. With its robust construction, flame retardant rating, and low temperature coefficient, the capacitor is ideal for any application in which stability of capacitance and accurate ripple current are important.
