Tantalum capacitors, also called Ta caps, are commonly used to store and discharge energy in the form of electrical current, allowing for a smooth release of power with minimal loss. They are designed to pass electric current between two terminals when a voltage is applied, making them invaluable components for a number of electrical applications.

The M39003/03-0203 is a type of axial leaded tantalum capacitor manufactured by specialist capacitor company AVX, renowned for their commitment to miniature component production. This particular component is notable for its anode-free construction, making it ideal for high-frequency applications requiring low ESR (Equivalent Series Resistance) and minimal leakage current.

The capacitor is constructed around two metal electrodes – the anode and the cathode – connected by a chemical compositional electrolyte, forming a three-element conductor. When electric current is passed through the capacitor, the induced voltage creates a static electric field between the electrodes, allowing the passage of a limited amount of current while controlling the flow of charge carriers.

Though the capacitor’s main purpose is to store and discharge electrical energy, its design also allows for the regulation of the electrical load in applications where quick changes in electrical current are required. This trait makes the M39003/03-02 ideal for use in automotive, video and communications applications.

Indeed, the capacitor is established as a much-needed component in a variety of motor control applications, ranging from the control of windshield electrical motors in automotive applications to the regulation of robotic motors in industrial settings. This is due to the capacitor’s ability to provide fast charge/discharge cycles without compromising on reliability, making it essential in applications that require repeated switching in order to maintain stable operation.

The capacitor’s unique attributes and miniature stature also make it valuable in less power-intensive application such as video editing, where it can be used to reduce line interference, minimize signal loss and provide indicator signals. Additionally, its robust design and low leakage current makes it an ideal choice for RF applications such as remote sensing and radio communication.

Aside from its impressive reliability, the main benefit of the M39003/03-02 is its relatively low cost, making it an accessible choice for a range of constrained budgets. Moreover, its tin-plated copper alloy terminal construction makes it particularly suited for environment with high levels of vibration, making it suitable for use in powerful industrial motors or even in more fragile applications such as toys.

All in all, the M39003/03-02 is an impressive Tantalum capacitor, offering quick charge/discharge cycles and extremely low leakage, all while keeping prices relatively low. Its miniature design makes it invaluable in a range of automotive, video and communication applications and its tin-plated copper terminals provide it with the additional benefit of being suitable for use in environments with high levels of vibration.
