Aluminum Electrolytic Capacitors are an essential component of any electronic device, providing a range of features and capabilities. The B41828A4688M is a specialized aluminum electrolytic capacitor that is designed for use in a range of applications.

It has a wide operating temperature range from -55°C to +105°C and a rated voltage of 25 VDC. It has a very low ESR (equivalent series resistance) of just 0.15 ohms. In addition, it has excellent thermal and mechanical shock resistance, along with a long life expectancy of 2000 hours at 105°C.

The B41828A4688M is a large device with a diameter of 28 mm and a height of 11.6 mm. It is a polarized device, allowing for the correct polarity when connecting it to the circuit. The capacitance range for this type of capacitor is 10µF to 470µF.

The primary application area for this aluminum electrolytic capacitor is in power supplies, particularly in high voltage applications. It is ideal for use in DC/DC converters and motor drives. Additionally, it is suitable for use in rectifiers, power amplifiers, and audio applications.

The working principle of an aluminum electrolytic capacitor is based on the phenomenon of electrochemical double-layer formation. An aluminum foil is coated on both sides with an oxide layer. When a voltage is applied, a polarization layer, also known as a ‘dielectric’, is formed between the two metal surfaces. This dielectric layer can store electrical energy, allowing it to be used as a capacitor. When the voltage is removed, the dielectric layer dissipates and the capacitor is discharged.

The B41828A4688M utilizes polarized capacitors to achieve a higher voltage rating. The polarization allows for a higher charge to be stored within the dielectric layer, increasing the capacitor’s voltage rating. In addition, it also has enhanced temperature performance due to tighter voltage tolerances over the operating temperature range.

The B41828A4688M is a versatile aluminum electrolytic capacitor that can be used in a number of applications. It is ideal for use in power supplies, DC/DC converters, rectifiers, power amplifiers, and audio applications. The working principle of the capacitor is based on electrochemical double-layer formation, allowing it to store electrical energy for use in electronic devices.
