The working principle of B41690A7398Q7 is similar to that of other aluminum electrolytic capacitors. When AC voltage is applied, a combining force is created between positive charged ions on the surface of the anode and negative liquid salt ions in the electrolyte. Electrolyte accumulations form on the surface of the anode and then the anode and electrolyte become polarized. The oxide film formed on the surface of the anode acts as a dielectric. It is a subparallel connection and the capacitance is the sum of two parts, namely the capacitance of the anode and the capacitance of the electrolyte. The working frequency of the capacitor is determined by the speed of the electrolyte ions with the applied voltage.

The B41690A7398Q7 is designed with a low ESR (equivalent series resistance) and a low ESR slope. This means that it can handle a wide range of operating frequencies, allowing it to be used in high frequency and high power applications. In addition, the B41690A7398Q7 has a large capacitance value (470μF) and a high ripple current rating (2.1A). This makes it ideal for many switching power supply applications. The rated temperature range is also very wide, making it suitable for demanding environments.

In conclusion, B41690A7398Q7 is a high-performance aluminum electrolytic capacitor designed for use in power supply, server power solutions, and communication networks. It has a wide temperature range, high ripple current rating, and low ESR and ESR slope. This makes it suitable for high frequency applications that require high performance.
