Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of polarized capacitor that utilizes a solid aluminum oxide or tantalum oxide as a dielectric. These capacitors use a chemical reaction to create a high electrical field between two electrodes, thereby storing electrical energy. They are commonly used in power supplies, electronic circuits, and industrial equipment.

The B41043A7157M aluminum electrolytic capacitor is defined by the J-Lead shape and a capacitance of 7.15μF. It utilizes a tantalum oxide dielectric and has a rated voltage of 100V. It has a wide operating temperature range of -55°C to +125°C and a lead spacing of 5.08mm. The capacitor has a low ESR of 1.5Ω and a high ripple current rating of 500mA.

Application Field

The B41043A7157M aluminum electrolytic capacitor is widely used in many applications, due to its high capacitance and low ESR. It can be found in many industrial applications, such as DC-DC converters, motor drives, switching power supplies, and UPS systems. It is also an ideal choice for use in monitoring systems, LED lighting systems, AD/DA converters, audio equipment, and automotive electronics.

Working Principle

The B41043A7157M aluminum electrolytic capacitor utilizes a solid tantalum oxide dielectric. This dielectric is formed through an electrolytic anodizing process, which involves the applying of a high electrical field to a sheet of aluminum foil, causing an oxide layer to form on its surface. The resulting oxide layer acts as a barrier to the passage of current, thus allowing the capacitor to store electrical energy within its internal structure.

Once the tantalum oxide layer has been formed, the capacitor is placed into an electrically-conductive casing. The two ends of the capacitor are then connected to two terminals, allowing for the passage of current. When an electrical potential is applied to the capacitor, then the internal electrical field generated by the oxide dielectric is able to store and release electrical energy as needed.

Conclusion

The B41043A7157M aluminum electrolytic capacitor is a high-efficiency, high-capacitance capacitor that is capable of storing and releasing large amounts of electrical energy. Its wide operating temperature range, low ESR, and high ripple current rating make it an ideal choice for many industrial applications, as well as monitoring systems, LED lighting systems, audio equipment, and automotive electronics.
