Tantalum capacitors are a special type of electrolytic capacitor that have an anode composed of solid tantalum and an electrolyte of manganese dioxide. They are used in applications where a high capacitance and a small size are essential, such as in telephone networks and computer systems, where storage of vast amounts of data requires lots of space and small size is important. The M39003/01-2287H is one such type of tantalum capacitor.

The M39003/01-2287H is a small, miniature, axial leaded, axial lead-thru-hole type tantalum capacitor with an electrically inactive epoxy case. It has a typical lifetime of 2,000 hours with a rated voltage of 20 Vdc and a temperature range of -55°C to +125°C. The capacitor has a capacitance of 330 μF and a tolerance of 20%, meaning that the actual capacitance can range from between 264 μF and 396 μF. It also offers a high insulation resistance, with a typical value of 1000 MΩ at 25°C.

The M39003/01-2287H is an ideal choice for applications requiring compact size, high reliability, and low leakage current. It is most often used for audio applications, such as loudspeakers, surround sound systems, car audio systems, and studio monitors, as well as in medical monitoring equipment, aerospace systems, and HVAC units. It can also be used for energy storage applications such as uninterruptible power supplies and surge protection.

The working principle of the M39003/01-2287H is based on the capacity of an charged solid tantalum plate to store a charge. When the capacitor is polarized, an electric current is passed through the manganese dioxide electrolyte. This charge is then stored in the solid tantalum plate as potential energy. The capacitor then acts like a reservoir for electrical charge, holding the charge as long as the voltage applied to it stays within its specified range.

In comparison to other types of capacitors, tantalum capacitors offer a unique combination of high capacitance and low size. They also offer low leakage current, making them a great choice for applications where leakage current can be a problem. In general, the M39003/01-2287H is a reliable and well-suited choice for a variety of applications requiring a miniature, reliable capacitor.
