Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used components in many electronic devices such as computers, televisions, electric appliances, electric motors, and communication devices. These capacitors are frequently found in the power supply, filtering and signal processing circuitries. Aluminum electrolytic capacitors are very popular components on the market due to their low cost, long life and high capacitance.

The B43454A9158M aluminum electrolytic capacitor is a miniature axial leaded, radial lead style device capable of handling 360V working voltages at various temperature and frequency conditions. This device is typically used power supplies, motor drives, frequency modulation, signal processing, reducing spikes and harmonic distortions. The device offers high ripple current capability and long durability due to its water-resistant metalized polyester film dielectric material. Additionally, a unique feature of this device is its solid electrolyte which gives high temperature and long life.

The working principle of the B43454A9158M aluminum electrolytic capacitor consists of three parts: electrolyte, positive plate, and negative plate. The electrolyte is a combination of aluminum and a chemical electrolyte. The positive plate is made of aluminum foil and the negative plate is made of a special paper impregnated with an electrolyte. As the voltage potential is applied, a current flows between the positive and negative plates and an opposing electrical field is created. This electrical field stores the energy as a capacitance. The capacitance value of the device is determined by the areas of the plates, the dielectric, and the electrolyte.

The rated capacitance of the B43454A9158M is 105mF at 100Hz and 20°C, with a maximum working voltage of 360VAC. Its capacitance changes with temperature by -3%/°C, and it also has a leakage current of approximately 0.5mA at 125°C. The rated life of the device is 2000 hours, and its maximum leakage current is 1.0mA at rated voltage and 125°C.

The B43454A9158M aluminum electrolytic capacitor is suitable for many applications including high-precision switches, A/D converters, DC-DC converters, power regulation circuits, and transducer circuits. It is also used in high current touch controls and linear circuit regulation. The device has an operating temperature range between -45°C to +125°C, and a storage temperature range between -60°C to +125°C. Additionally, the device is RoHS compliant and is built to very high standards.

In conclusion, the B43454A9158M aluminum electrolytic capacitor is a robust and reliable component suitable for many applications. It offers high capacitance, low leakage, and long operational life. This device is also low cost, making it an ideal option in many applications.
