The capacitor is rated for ripple current up to 1.2A at 85°C and 1kHz.

Working Principle of the MAL213631151E3 Aluminum-Electrolytic Capacitor

The MAL213631151E3 aluminum-electrolytic capacitor employs a unique dielectric. It is constructed from a positive plate, a negative plate, a separator, and electrolyte. The positive plate is made from aluminum foil and is covered with an oxide film. The film acts as the capacitor’s dielectric which provides a very high dielectric constant. The capacitor is also polarized, meaning that the voltage applied to the positive plate must always be higher than that of the negative plate, otherwise the capacitor may be damaged.

When voltage is applied to the capacitor, a current will flow between the positive and negative plates, resulting in the movement of ions within the electrolyte. This ionic flow charges the capacitor’s dielectric, resulting in a stored electrical energy and an elevated potential difference between the positive and negative plates. This potential difference is referred to as capacitance and is measured in Farads. As the voltage applied to the capacitor increases, so will the capacitance.

Conclusion

The MAL213631151E3 aluminum-electrolytic capacitor is an ideal choice for applications requiring high capacitance and low ESR in a small package. The capacitor utilizes a unique dielectric material that offers a high capacitance-to-size ratio. Additionally, the capacitor is able to provide long capacitance stability and maintain low ESR over a wide temperature range. The capacitor is suitable for a variety of applications, such as power supply filtering, audio circuit buffering, resonator applications, suppressed base current discharge, and high power supply commutation.
