Tantalum capacitors are an important type of surface mount component that is widely used in a variety of applications requiring very small packages and good capacitance stability. The M39003/03-3039/TR is an example of one type of smaller tantalum capacitor. It has long been used in high-frequency switching power supplies due to its excellent performance characteristics and long-term reliability.

The M39003/03-3039/TR is a small and inexpensive three-terminal chip capacitor that can be used in a variety of applications. It has a capacitance value of 4.7µF with a tolerance of 20%. It has a rated working voltage of 35V and a rated ripple current of 2.5A. Its operating temperature range is -55°C to +125°C.

The M39003/03-3039/TR capacitor is constructed of a sintered tantalum anode element with two attached, oriented tantalum oxide dielectric layers and a wirebonded, formed tantalum pellet cathode. Its three terminals are the anode, cathode and vented terminals. The vented terminal provides the appropriate venting area to release the pressure in the event of an excessive electrical event.

Tantalum capacitors, such as the M39003/03-3039/TR, exhibit excellent high temperature stability, excellent high frequency characteristics, and low voltage drops. They can also handle large amounts of bias current, which makes them well suited for applications where high levels of bias current are required. This also makes them an ideal choice for high voltage applications, where a relatively low amount of capacitance is required.

In terms of working principle, a tantalum capacitor works by storing electrical energy and releasing it when needed in the form of electrons. The anode of the capacitor is the negative terminal, while the cathode is the positive terminal. When an electric current passes through a capacitor, electrons are attracted to the positive terminal and will accumulate there. This creates an electrical field in the capacitor, which stores the energy. When the electric current is stopped, the electrons return to the anode, releasing the stored energy. The result is a decrease in the voltage at the anode.

The M39003/03-3039/TR tantalum capacitor is an ideal choice for a wide variety of applications, including high-volume consumer electronic designs, data processing systems, power supplies, audio equipment, automotive electronics, and medical equipment. Its simple construction and superior performance make it a reliable choice for many applications.
