Tantalum capacitors are polarized capacitors with anode terminals made from tantalum metal and a cathodic electrolyte made from either a sintered tantalum anode with a solid manganese dioxide (MnO2) dielectric, or from a conductive polymer. The M39003/01-8372/HSD model is an industry-standard small surface-mount tantalum capacitor from Cornell Dubilier that is used for various applications that require high voltage and high capacitance in a small package.

Applications

The M39003/01-8372/HSD model is ideal for applications that require stability and reliability. Its wide operating range makes it suitable for use in high-efficiency switching circuits, voltage regulation circuits, and power supplies. It is used in automotive and avionics applications as well. It is highly reliable and has a long lifespan, which makes it an ideal choice for critical applications. It can also be used in audio circuits and radio frequency (RF) amplifiers.

Working Principles

The M39003/01-8372/HSD model has an anode made from tantalum rods that are etch-sealed to a dielectric cup filled with solid electrolyte. The cup is then welded to an insulated metal lead frame assembly. A manganese dioxide (MnO2) dielectric is then applied to the anode. An insulating layer of sintered tantalum powder forms the cathode. The two electrodes are then connected together with a thin film of tantalum oxide.

The MnO2 dielectric material provides high capacitance and efficient current flow between the anode and cathode. It also helps protect the capacitor from thermal and electrical stresses. The MnO2 dielectric also helps to maintain capacitance stability after long-term use. The ceramic bead and sealing material provide a highly resistant seal which helps ensure the capacitor\'s performance under high temperature and pressure.

The M39003/01-8372/HSD tantalum capacitor is also designed to operate with low loss and low noise. It has an excellent energy density to volume ratio that makes it ideal for applications where space is limited. It also offers good stability under different temperatures. It has a wide range of operation temperature, making it suitable for a wide range of applications.
