Introduction

Tantalum capacitors are reliable, long-lasting components used in a variety of electronic applications, especially those that require robust temperature tolerance and stability. Positioned between disc and chip capacitors on the capacitance-size scale, tantalum capacitors are made with tantalum, an element found in the periodic table. They are commonly used in automotive, space, and medical applications due to their smaller size, high capacitance-to-size ratios, and high temperature performance. The M39003/01-2291/HSD device is one of the more robust and advanced versions of these capacitor packages currently available.

M39003/01-2291/HSD Application Field

The M39003/01-2291/HSD is particularly well-suited for use in car electronic circuits and miniaturized systems that require a large amount of power. This device is designed to provide high capacitance and endurance in harsh, high-temperature environments, making it perfectly suitable for use in automobile and other vehicle applications. This type of capacitor is also suitable for high-performance telecom circuits, power electronics, and computers. The miniaturized size allows these capacitors to fit into the tightest spaces, allowing electronic engineers to cram more components into a given area.The M39003/01-2291/HSD also provides a substantial capacitance range selection, from 0.47uF-62uF, providing engineers with increased flexibility when designing their circuit. The M39003/01-2291/HSD also utilizes a unique casing partitioned into two chambers, resulting in a long-term rated life in high temperature environments of up to 10,000 hours. This capacitor features a wide range of voltage varieties from 25V – 150V, with the maximum operating temperature tolerance at up to 85 degrees Celsius.

Working Principle

Tantalum capacitors contain a solid tantalum pellet anode, which is surrounded by an electrolytic solution and a tantalum pentoxide dielectric layer, which is in turn encased in a conductive, insulating container. When a DC voltage is applied to the component, the tantalum material in the anode releases oxygen, enabling a second thin dielectric layer to form. This dielectric layer, which is very effective against leakage, will store energy even when the voltage is removed.The electrolytic solution inside the container uses an electrolyte that is strongly attracted to the positive electrode inside the capacitor, which is the anode. This allows electrons to flow easily in one direction, while blocking electron flow in the opposite direction. This helps preserve the energy stored inside the capacitor over extended periods of time.

Conclusion

The M39003/01-2291/HSD is an advanced tantalum capacitor ideal for all sorts of automotive, space, and medical applications. This capacitor has a long-term life rating of up to 10,000 hours and can withstand temperatures as high as 85 degrees Celsius. Its wide capacitance range of 0.47uF - 62uF, along with its wide selection of voltage varieties from 25V–150V, makes it perfect for high-performance circuits. The miniaturized size also allows it to be used in extremely tight spaces. The working principle of a tantalum capacitor is based on the release of oxygen from the anode which allows a second layer of dielectric protection to form, protecting the stored electricity from leakage and preserving it over time.
