Aluminium electrolytic capacitors (AECs) are used extensively in all types of electronic equipment, from computers to cell phones, and have recently become a popular choice for power applications. The MAL219846121E3 is a 125µF/200V variant of AEC manufactured by Cornell Dubilier, a US electronics components manufacturer.

The MAL219846121E3 is suitable for operating temperatures range of -55°C to +125°C and works on a wide range of frequencies from 10kHz up to 1MHz. This has made the model a popular choice for high temperature or high frequency applications. It is also well-suited for medium-high power applications due to its higher rated voltage and robust design. The current leakage and noise level of the MAL219846121E3 are both exceptionally low.

Corner Dubilier has designed the MAL219846121E3 with a radial, snap-in design which is especially convenient for PCB installation and similar mounting applications. The terminals are also tin-plated for enhanced corrosion resistance and durability. The size of the model is relatively small at 24.5 x 59.8mm, making it ideal for projects where space or weight constraints need to be considered.

AECs like the MAL219846121E3 work on the basis of electrolysis. This is done by using two reactive elements, known as an anode and a cathode, in an electrolyte solution. When a small voltage difference is applied between the two terminals, a current will flow and reactive components will be formed on the surface of the anode. These reactive components are what forms the capacitance.

The capacitance value of the MAL219846121E3 can be tuned by adjusting the current through the anode and cathode. In addition, its self-healing properties make it well-suited for use in AC circuits, as the capacitor can quickly recover from voltage spikes caused by overvoltage or other transient events.

Overall, the MAL219846121E3 is an ideal choice for high temperature or high frequency applications such as light electric vehicles, control systems, switch mode power supplies, and inverters. Its snap-in design also makes it suitable for PCB installation and similar mounting applications, while its small size and low power consumption are beneficial for space and weight constraints. With its decent self-healing qualities and low current leakage, the MAL219846121E3 is well-suited for AC circuits.
