Tantalum capacitors are a type of electrolyte capacitor, they are widely used for their compact size and high capacity in various electronic circuits. The M39003/01-2686H is an example of a size code for a single-ended tantalum capacitor. It is a surface mount capacitor designed to be used within the range of working temperatures ranging from −55°C to +85°C.

The M39003/01-2686H has a capacitance rating of 220µF and a voltage rating of 6.3V. The capacitor features a case sized at 85°C (L x W x H) 8.35mm x 5.75mm x 4.86mm. The capacitor also includes a ripple current rating of 350mA with an equivalent series resistance (ESR) of 0.25 Ω maximum at 100kHz.

The working principle of tantalum capacitors is based on the principle of electrolytic capacitors. In an electrolytic capacitor, an anode is composed of tantalum metal which is covered by an insulating oxide layer. A second metal plate, the cathode is placed in contact with the electrolyte. The electrolyte then functions as an ionic conductor creating a space charge layer between the two plates which produces a capacitive effect. When an alternating current is applied to the circuit, a change in the space charge layer occurs and this creates the capacitor’s electrical field, resulting in current flow.

The M39003/01-2686H is an excellent choice for use in a circuit with high frequency noise, as it offers good filtering performance up to 100 kHz. Its size makes it ideal for applications where a small footprint is required, such as those found in portable devices.
