Tantalum capacitors offer a tantalizing combination of high capacitance, small size, lightweight design, and prolonged operational life. The M39003/01-5716 is an example of a tantalum capacitor that has a wide range of applications and working principles.

The M39003/01-5716 has a voltage rating of 6.3 to 30Vdc, with a capacitance range of .1 uF to 100 uF. This wide range of capacitance enables the capacitor to be used in a variety of applications. For example, it can be used in handheld electronics, audio equipment, and HVAC systems. It can also be used in power supplies, motor control circuits, and power amplifiers.

The capacitor utilizes a sintered tantalum anode and a wet electrolytic cathode to provide superior voltage and thermal stability. The tactile hermetically sealed parts are encapsulated in an epoxy package to protect the circuit elements from harsh environments such as mechanical vibration, moisture, and temperature extremes.

It also ensures that the capacitor retains its electrical properties over extended periods of time. Additionally, the capacitor is designed to reduce the amount of noise generated by the circuit, which improves system performance.

The working principle of a tantalum capacitor involves the migration of charge carriers (typically lithium ions) from the anode to the cathode when a voltage is applied across the terminals. This migration of charge carriers produces an electrical field within the capacitor, which is responsible for the device’s capacitance. Additionally, this electrical field creates a barrier, which prevents the charge carriers from delocalizing and losing their capacitance.

As the applied voltage to the capacitor increases, the effect of the barrier is reduced as the electric field strength increases, thus increasing the amount of charge carriers that can delocalize and reducing the capacitance of the device. This phenomenon is known as “dielectric absorption” and is a common problem with tantalum capacitors. To overcome this problem, tantalum capacitors are typically designed with a higher initial capacitance.

The M39003/01-5716 is an ideal choice for applications that require a capacitor with a wide range of capacitance. The high voltage rating and epoxy encapsulation ensures that the device will retain its electrical properties over long periods of time and in harsh environments. Additionally, the capacitor’s working principle and inherent design features make it an excellent choice for a variety of applications.
