Tantalum Capacitors

M39003/09-0376H is a solid-state, electrolytic capacitor, specifically a tantalum capacitor. Tantalum capacitors consist of two electrodes, commonly referred to as the anode and cathode, and use tantalum pentoxide as the dielectric material. They are used as energy storage capacitors in wide variety of electronic systems, ranging from communication systems to automotive electronics.

M39003/09-0376H is a surface-mount, ceramic capacitor designed for use in portable electronic components like cell phones and PDAs. It has an extended temperature range and high current surge capability. The capacitor is designed for through-hole as well as surface-mount applications. It is available in lead (Pb) tin (Sn) and gold (Au) finish.

M39003/09-0376H capacitors are particularly well suited for high-frequency voltage filtering, signal coupling, and DC blocking—applications that require low ESR. They are widely used in high-voltage switching circuits, buffering, and high-speed memory usage.

The working principle of a tantalum capacitor is similar to most other capacitors. The anode is made of either sintered tantalum or tantalum powder, with a dielectric of tantalum pentoxide. The anode is usually formed into a pellet that is then pressed into a metal can to provide a reliable connection. The cathode is typically made of manganese dioxide, along with a noble metal binder and an oxide coating.

When a voltage is applied across the terminals of the capacitor, the anode forms an electric field with the dielectric and the cathode. This field causes electrons to move across the dielectric, creating an electrical charge. The charge stored is proportional to the applied voltage. When the voltage is removed, the charge gradually dissipates and the capacitor is ready for reuse.

M39003/09-0376H tantalum capacitors are available in various capacitance values ranging from 10μF to 10mF, with a nominal working voltage range of 10V to 50V. They also feature excellent temperature and frequency characteristics. These capacitors are available in a variety of packages—from low-profile packages to standard and leadless packages, making them ideal for a range of applications.

M39003/09-0376H tantalum capacitors are reliable and offer superior performance, making them a popular choice for a wide range of electronic applications. They provide low ESR and voltage ratings of up to 50V, and have excellent temperature and frequency characteristics.
