Tantalum capacitors are electronic components with unequalled characteristics. They combine very high capacitance and volumetric efficiency with low equivalent series resistance (ESR). They have wide range of applications which span through consumer electronics, automotive and industrial products, and communication systems. The M39003/03-4025/TR is a chip type tantalum capacitor, which is manufactured by Kemet Electronics with anode and cathode connecting directly through the metal terminals. It is designed to meet the requirements of the MIL-PRF-29504/2 and M39003/4-01B specifications.

M39003/03-4025/TR is available in case sizes with three different lead spacing options (0.1", 0.2", 0.4") and in + 10%, - 20% tolerance. The capacitor also has a wide range of capacitance values from 0.1µF to 330µF with voltage ratings from 6.3V to 25V. It features solderable termination suitable for automated soldering methods. It offers RoHS compliant options and Pb-free terminations. The capacitance of a M39003/03-4025/TR capacitor depends on the cathode voltage applied to the cathode terminal. It has a capacitance variation of +20%, -10% when used in the temperature range of −55°C to +125°C.

The working principle and application field of M39003/03-4025/TR is based on the Tantalum Oxide semiconductor. A tantalum oxide semiconductor is formed when positively charged Tantalum ions are attracted to the oxidized layer on the surface of a capacitor-grade tantalum pellet. When a voltage is applied to the anode and cathode, electrons are attracted to the anode, and a negative charge is applied to the tantalum pellet\'s surface. The positively charged Tantalum ions are then attracted to the negative charge, forming a solid electrolytic layer. This electrolytic layer is the capacitive component of the capacitor.

M39003/03-4025/TR is widely used in applications such as automotive, computers, consumer electronics, power supplies, medical devices, and military/aerospace. It can be used in energy storage, filtering, decoupling, and timing applications. It is used to provide intermediate DC voltage levels for switching applications. It can also be used for start-up and severe safety devices.

The M39003/03-4025/TR capacitor also has a very low thermal resistance, making it particularly suitable for high temperature or high current applications. It also has a low equivalent series resistance (ESR) which ensures that it can provide an excellent signal response.
