Tantalum capacitors, or tantalum capacitance devices, are used for power supplies, electronics, and circuit design in a wide range of applications. This type of capacitor is available in two distinct designs: polymer and wet-tantalum. Both types utilize an electrolyte solution and a porous formed anode, however the polymer version relies on an organic solid-state electrolyte instead of the more common wet-tantalum version. The M39003/01-5440/99 is a high-value, wet tantalum capacitor released by the Microchip Corporation in 2020. This capacitor enables higher capacitance values than standard tantalums and features an improved shelf life when compared to earlier models.The M39003/01-5440/99 capacitor is a multi-anode device that utilizes a conductive polymer as an electrolyte and a porous formed anode to store electrical energy. This capacitor is designed specifically to offer a higher capacitance in a much smaller package than other tantalum capacitors. The advantage of this capacitor is that it does not require a long aging period and can be used for a wide variety of applications. The operating voltage of this capacitor is between 6-12 volts, and its maximum operating temperature is 125°C.The working principle behind this type of capacitor is fairly simple. When a voltage is applied across the capacitor, a charge is stored due to the formation of an electric double layer on the surfaces of the anode and electrolyte. This electric double layer creates an electrostatic field, which attracts ions from the electrolyte to the electrode. These ions form the capacitance, allowing energy to be stored. When the voltage is removed, the electric double layer and the ions return to their original positions and the energy is released.The M39003/01-5440/99 capacitor is designed for high-frequency applications such as crystal oscillators, pulse control circuits, and clock frequency generators. It is also suitable for general-purpose power supplies, filters, decoupling, and low-pass applications requiring higher capacitance values. This type of capacitor is ideal for long-term reliability and can handle an extended temperature range while still providing reliable performance.In conclusion, the M39003/01-5440/99 is a wet-tantalum capacitor with a polymer electrolyte and a conductive polymer. It is designed for high-frequency applications requiring high capacitance values and a long lifespan. Its operating voltage is between 6-12 volts, and its maximum operating temperature is 125°C. This capacitor offers improved shelf life when compared to earlier models, and is suitable for a wide variety of applications.
