Tantalum capacitors, also commonly referred to as ta-caps or tant-caps, are electrochemical capacitors made from tantalum, a rare metallic element. Tantalum capacitors are compact and lightweight due to their thin metal film layers. They have incredibly low leakage currents, making them ideal for high-temperature and radiation-resistant applications.The M39003/01-7204/TR is a tantalum capacitor specifically developed by Vishay Intertechnology, and consists of two plastic cases which hold a sintered anode of pure tantalum powder. The capacitor is designed for use in circuits with frequencies of up to 150 MHz, and offers high capacitance, low ESR (equivalent series resistance), and excellent reliability.The M39003/01-7204/TR is primarily used in coulomb measurement applications where space-constraints are a factor. These measurements include those related to integrated circuits and embedded systems, printed circuit boards, gate drive and power supplies, and more.When used in coulomb measurement applications, the M39003/01-7204/TR is arranged in a 2S1P (2 series, 1 parallel) configuration. This configuration allows for a higher capacitance value at a given physical size than could otherwise be achieved by a single component. The 2S1P configuration can also help to reduce ESR by up to 50%.The working principle of the M39003/01-7204/TR is the same as that of all other tantalum capacitors. A negative charge is stored at the anode, while a positive charge is stored at the cathode. When power is applied, current flows through the capacitor and the charges are collected at the respective nodes. This will establish an electric field in the depletion region that acts to oppose further current flow.The M39003/01-7204/TR capacitor boasts excellent characteristics for low-power coulomb measurement applications. It offers a capacitance value of 0.47 μF and extremely low ESR. It also has a maximum operating temperature of 125°C and wide resistance to shocks, vibrations, and temperature cycling.The M39003/01-7204/TR capacitor offers a good mix of performance and reliability, making it suitable for a range of applications. It is well suited for use in high-temperature environments, such as automotive ECUs and power modules, as well as those that require radiation-resistant characteristics. It is also well accepted by the military for use in mission-critical operations, as it offers exceptional durability and reliability.Overall, the M39003/01-7204/TR is an excellent choice for low-power coulomb measurement applications. It offers a mix of performance and reliability that is hard to match—making it ideal for a range of applications, including those in the automotive and military sectors.
