Tantalum capacitors are a type of electrical capacitor, often used to store charge in small electronic circuits. Tantalum capacitors are widely used in many applications due to their high capacitance, small size, and reliability. The M39003/03-2076 is a particular type of tantalum capacitor made by Stackpole Electronics and designed for surface mount applications.

The M39003/03-2076 is a low profile, high capacitance chip capacitor featuring low equivalent series resistance (ESR) and low dissipation factor (DF). This capacitor is offered in two termination styles: solid anode and solder plated anode, each with three capacitance ratings (3.3μF, 4.7μF, and 6.8μF). It is rated for operating temperatures up to 125°C. Additionally, the M39003/03-2076 has a failure rate of 0.26% per 1000 hours at 125°C and has superior ESR/DF values compared to competing capacitors.

The M39003/03-2076 tantalum capacitor has a wide range of applications. Common applications include storage of high voltage in compact circuitry, power supply bypassing, and filtering. It is well-suited for use in laptop motherboards, circuit boards, and flow control applications due to its miniature size and low profile. Additionally, the M39003/03-2076 is frequently used in high-precision instrumentation, aerospace, medical, and military applications.

The working principle of tantalum capacitors is based on the ability of a conductive plate to store electric charges. When electric potential is applied to two adjacent plates with an insulating material between them, charge accumulates in each plate. The capacitance of a capacitor is determined by the size of the plate, the area overlapping between plates, and the dielectric constant of the medium between them. In the case of tantalum capacitors, the dielectric material between the two plates is a tantalum oxide compound, which further improves the capacitance of the capacitor.

The M39003/03-2076 tantalum capacitor is a reliable and versatile device that can be used in a variety of applications. Its small size, low profile, high capacitance, and low ESR make it ideal for use in high-precision instrumentation, aerospace, medical, and military applications. Its wide range of ratings ensures that the M39003/03-2076 can be used in both low and high voltage applications, making it an excellent choice for power supply bypassing and filtering.
