Aluminum electrolytic capacitors are a type of capacitor that use aluminum oxide as its electrolyte, allowing a higher capacitance than normal capacitors. The B41002A8155Mis an aluminum electrolytic capacitor used for specific tasks. This part is from the B series from TDK (Tokyo Denki Kogyo).

Application Field
The B41002A8155M is an Aluminum Electrolytic Capacitor designed for moderate power supplies. It is rated for 105°C, with a voltage rating of 10V. It has 1/4 in x 1/8 in dimensions and is designed to fit standard consumer electronic product. The capacitor also features high E.S.R compared to solid polymer capacitors, this combined with its long life and solid performance make the B41002A8155M an ideal candidate for consumer electronics, such as power supplies, portable DVD players, game consoles, stereo systems and other electronic products requiring high voltage and long life.

Working Principle
The B41002A8155M aluminum electrolytic capacitor works by using aluminum oxide as its secondary dielectric material. This allows the capacitor to have higher capacitance then a traditional bare capacitor. The capacitor is charged when a voltage is applied on the capacitor terminals (the polarity must be positive for the anode and negative on the cathode). When this occurs, the positive plate (anode) begins to attract the negative ions of the electrolyte. This process creates a current that causes the negative plate (cathode) to discharge the electrons which in turn charge the positive plate. This then causes the positive plate to reject the negative ions, and the current to stop. This process continues, and creates a capacitance between the plates.

When a large current is drawn from the capacitor, the aluminum oxide film on the capacitors surfaces can break down, causing the voltage to be lowered. To reduce the chance of this happening, the designers have used an electrolyte which has a higher dielectric constant and higher capacitance, allowing the aluminum oxide to withstand more current before it breaks down.

The B41002A8155M also has a high Ripple Current rating, meaning it can withstand high currents flowing in and out from the capacitor’s terminals. This makes it an ideal capacitor for powering large consumer electronics, as the capacitor will cause minimal ripple current, preserving the power supply lifespan

These aluminum electrolytic capacitors are high-quality capacitors and are reliably used in a wide range of applications including consumer electronics, power supplies, and audio equipment. The B41002A8155M is capable of providing up to 10 VDC, allowing it to be used in a large range of electronic products such as power supplies, CD players, amplifiers, and other consumer electronic products. The combination of the high E.S.R., long life and design features make the B41002A8155M an ideal choice for applications requiring moderate power supply voltage and long life.
