Aluminum electrolytic capacitors are widely-used, passive components found in a variety of electrical and electronic systems and applications. The B41252B4129M is an aluminum electrolytic capacitor from the B4-series of electrolytic capacitors produced by Vishay, a major component manufacturer. This aluminum electrolytic capacitor is characterized by its high capacitance between 15µF to 6250µF, and voltage ratings ranging from 25 VDC to 500 VDC.

The relative physical size of electrolytic capacitors is small compared to their capacitance values, making them one of the most cost-effective and efficient solutions for many electrical and electronic needs. Along with their low cost and high capacitance value, they also offer a long life expectancy and are highly reliable. The aluminum electrolytic design is also capable of withstanding very high voltages, making them ideal for high power applications.

The B41252B4129M is a high voltage, high temperature series of aluminum electrolytic capacitors from Vishay. This series of capacitors is designed for a variety of circuits, handling high voltages (up to 500 V) and high operating temperatures (up to 125° C). The capacitance values range from 15µF to 6250µF, and are offered in both radial and snap-in leaded packages.

The B41252B4129M utilizes a combination of aluminum foil (anode) and organic film and/or paper (as the cathode) separated by the electrolyte (usually an acidic solution). When a voltage is applied across the terminals of an electrolytic capacitor, leads, or plates, the anode material will become positively charged and begin to oxidize. This creates a thin oxide-scale layer on the anode. This layer serves as a barrier and allows current to flow through the capacitor in one direction only. The electrolyte is also affected by the voltage, as it now contains ions as well as neutral particles. The individual particles remain in place underneath the oxide layer, while the ions move towards the negatively charged cathode material, producing the required electric field to sustain the capacitance.

The B41252B4129M aluminum electrolytic capacitors are ideal for use in harsh environments or in applications where high temperatures are required. This makes them well-suited for power supplies, signal filtering, and DC blocking applications. Applications such as power supply noise, emergency lighting, and DC motors also require capacitors that are able to absorb the heat generated during their use and these aluminum electrolytic capacitors can meet these needs.

Aluminum electrolytic capacitors are a low-cost, highly reliable, and reliable solution to many electronic and electrical requirements. The B41252B4129M series from Vishay provides high capacitance, long-life, and high voltage capabilities making them an ideal solution for many applications. They offer excellent high frequency characteristics and high current capabilities, while being inexpensive and simple to install.
