Aluminum electrolytic capacitors are a type of capacitor that uses an electrolytic solution to store electrical charge and are well known for their large capacitance values per unit volume. The WBR8-250A aluminum electrolytic capacitor is a very compact, high performance component. This electrode has a high volumetric efficiency and self-healing properties, allowing it to be used in many sensitive and challenging applications.

The WBR8-250A has a lead-free case and a rated capacitance of 8 µF and a rated working voltage of 250 VDC. The capacitor has a temperature range of -40 to +85°C, and a tolerance of ±20%. It is constructed with a single aluminum foil winding, and utilizes a liquid electrolyte encapsulated in a case that is welded for optimal performance.

The working principle of the WBR8-250A aluminum electrolytic capacitor is based on the use of Faraday’s law of electrolytic conduction. When a voltage is applied across its two terminals, an electric field is created in the electrolytic solution, and free electrons move across the field, forming a current. When the current is stopped by the depletion of mobile ions, an electric charge is stored, forming a capacitor.

The WBR8-250A aluminum electrolytic capacitor is designed for a wide range of applications, including power supplies, motor drives, battery back-up, and industrial equipment. It is often used as a filter capacitor in circuits to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). The WBR8-250 aluminum electrolytic capacitor is also used in audio equipment, automotive products, and communication systems, for high speed switching, such as in telecom circuits.

The WBR8-250A aluminum electrolytic capacitor has a wide range of advantages, including long life, low leakage, low dissipation factor, and high ripple current. It offers excellent reliability and is not affected by extreme temperatures, humid environments, or shock. Additionally, the capacitor has a high volumetric efficiency, allowing it to be used in small and tight spaces. This makes the WBR8-250A capacitor a suitable choice for many demanding applications.
