• B43640E2128M000 Application Field and Working Principle

Aluminum electrolytic capacitors are a type of capacitor that uses an electrolyte to store energy. They are a cornerstone of modern electronics and are used in a wide variety of applications. The B43640E2128M000 capacitor is a widely used aluminum electrolytic capacitor with an operating temperature range of -55°C to +105°C. It has a wide operating voltage range of 2.5 up to 63Vdc and can handle currents up to 3A. Additionally, it has a capacitance of 3.3µF and an ESR of 3.8mΩ.

The B43640E2128M000 capacitor is a polarized capacitor, meaning that there is an anode and cathode side. In electrolytic capacitors, the anode side is chemically etched, and is wetted with electrolyte. This etching creates an oxide layer that acts as a dielectric. Electrons collect on the cathode side, creating an electric field and allowing energy to be stored. When a voltage is applied across the terminals, the capacitor charges and eventually reaches equilibrium.

Aluminum electrolytic capacitors are commonly used in power supplies, in electric motors and in battery back-up circuits. In power supplies, they are used to filter the power and reduce voltage ripple. In electric motor circuits, the capacitors play a large role in starting the motor and in determining its operating speed. Additionally, aluminum electrolytic capacitors are used in battery back-up circuits to protect against voltage and current fluctuations.

The B43640E2128M000 capacitor is a robust and reliable component, and it is well suited for a variety of applications. Its wide temperature range, ability to handle high currents, and low ESR make it an excellent choice for many applications. It is an effective, reliable solution for designers looking for an affordable, high performance capacitor.
