HV101943U020BJ0B

Aluminum electrolytic capacitors are an important type of capacitor used extensively in electrical and electronic circuits. The HV101943U020BJ0B is a non-solid aluminum electrolytic capacitor. It belongs to the range of high-voltage aluminum electrolytic capacitors from Vishay. The capacitor is rated at 200 V, 43µF and ± 20% tolerance. This means that over a range of temperatures, it can handle voltage up to 200 V and store/release up to 43µF of charge.

The capacitor is designed for applications requiring high levels of reliability and long-term stability. It is suitable for critical use in power supplies for industrial, telecommunications and medical applications. Due to its long-term stability, the capacitor is also suitable for military applications as well.

The basic working principle of the HV101943U020BJ0B aluminum electrolytic capacitor is that an electrolyte comprising of an ionic conducting material is sandwiched between two layers of conductive material. The conductive material can be made out of aluminum or tantalum. In the case of the HV101943U020BJ0B, it is made out of aluminum. A side of the capacitor is then polarized with a positive voltage while the other side is polarized with a negative voltage.

When a voltage is applied across the capacitor, the positively and negatively charged ions move into the electrolyte, creating a current that charges the capacitor. The aluminum blocks the positively charged ions and helps the negative ions create an electric field. This allows the capacitor to store and release the charge by controlling the movement of the ions.

The two plates of the capacitor are made out of commutated tantalum or aluminum foil, depending on the type of capacitor. The electrolyte is usually an aqueous solution of an acetic acid or an alkaline solution of an ammonium salt. The electrolyte is sealed to prevent evaporation and leakage of the charge.

The capacitor also has a dielectric layer made from a thin oxide film on the aluminum plates. This layer helps to increase the capacitance of the capacitor by being a relatively strong barrier between the two plates, storing more charge on each plate. This layer also helps to improve the life of the capacitor.

The combination of the aluminum plates, electrolyte and dielectric layer makes the HV101943U020BJ0B aluminum electrolytic capacitor a reliable choice in applications requiring high levels of reliability and long-term stability, including those in power supplies, telecommunications, medical and military applications.
