Tantalum capacitors have become the go-to choice for many designers looking to keep their board size and weight to a minimum. Available in low-profile, axial lead, surface mount and chip varieties, the M39003/01-7115 tantalum capacitor is a prime example of the benefits that tantalum capacitors bring to the table.

Typical applications for these tantalum capacitors include filtering noise and ripple in power supplies, as well as timing and coupling circuits. The M39003/01-7115 capacitor is also ideal for use in high voltage power supplies, voltage regulator modules, satellite radio and navigation systems, motion control circuits, and control and switching circuits.

The main advantage of the M39003/01-7115 capacitor is its miniaturized footprint. Its size enables designers to cram a higher level of components onto a circuit board. The capacitors have high voltage ratings of up to 56 V and capacitances ranging from 10 to 56 µF, allowing them to meet a wide variety of applications.

The M39003/01-7115 tantalum capacitor is also revered for its low dielectric absorption and low losses, which help maintain clean signal transit times. The capacitors also feature low equivalent series resistance (ESR), making them a good choice for high pulse current applications, such as in power supplies or defibrillators. The capacitor’s excellent temperature coefficient also helps to ensure maximum benefits are achieved over a wide temperature range.

But the real highlight of the M39003/01-7115 tantalum capacitor is its non-polarized design, which allows for easy mounting and assembly. This makes it suitable for use in any orientation, meaning it can be used in more confined spaces. The capacitor also offers high volumetric efficiency, meaning that a larger rated capacitance can be fitted in the same space and cost as a smaller rated traditional capacitor.

The working principle behind M39003/01-7115 capacitors is straightforward. They use two conducting metal plates or surfaces to load electrical charge onto an insulator known as a dielectric. Although the conducting materials used are different, such as Tantalum or aluminum for capacitors, they still work on the same principle. When a voltage is applied between the conducting surfaces, electrons will start to move along the metal plate thus creating an electric current.

The flow of current causes an accumulation of charges on either side of the plates. This is known as electrical polarization and results in a voltage potential that is equal to the applied voltage. The field generated due to the polarization of the capacitor acts as a shield against alternating currents but allows steady currents to flow freely. Thus, the capacitor can filter out noise and ripple in power supplies, as well as in timing and coupling circuits, while allowing direct current to pass through freely.

The M39003/01-7115 tantalum capacitor is a well-rounded capacitor ideal for use in a range of applications due to its small size and non-polarized design. It is also highly efficient and reliable, meaning it can provide stable, long-term performance even in demanding applications.
