Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an electrolytic or “wet-type” capacitor, is a type of electrochemical capacitor. Unlike other types of capacitors, they are made of two aluminum foils, which are separated by an electrolyte, usually an aqueous solution of ethylene glycol, boric acid and water. The electrolyte provides a dielectric medium that is responsible for the capacitor’s ability to store and release electrical energy. Aluminum electrolytic capacitors are commonly used for filtering, wave-shaping, bypassing and buffering applications.

B41858C5108M000 Application Field and Working Principle

The B41858C5108M000 is a series of aluminum electrolytic capacitors from EPCOS. These capacitors feature a capacitance range of 10 µF to 3,300 µF and a rated voltage of 16 VDC to 250 VDC. The B41858C5108M000 capacitor series is constructed from a cylindrical aluminum case with a prior-coated epoxy resin coating. The capacitor also features snap-in terminals, an insulated mount and a plug-in bushing.

The B41858C5108M000 capacitor series utilizes an anisotropic electrolyte, which is an electrically conductive gel-like substance that bridges the gap between the positive and negative electrodes of the capacitor. This enables the capacitor to store electrical energy and maintain a constant voltage even under high levels of current. The anisotropic electrolyte also increases the capacitors’ stamina by providing superior performance when exposed to high temperatures, shock and vibration.

The B41858C5108M000 capacitor series is mainly used in power supply filter applications. The series also features various types of temperature coefficients and extended working temperatures for applications in harsh environments. The series can also be used in higher frequency applications, as the capacitors have a low equivalent series resistance (ESR). Furthermore, the series offers a selection of surge voltage variations for various applications.

In conclusion, the B41858C5108M000 capacitor series is an ideal choice for power supply filter applications due to its anisotropic electrolyte, low ESR, and selection of temperature coefficients and extended working temperature range. The series’ range of surge voltage variations also makes it ideal for use in high frequency applications.
