Introduction to Tantalum Capacitors:
Tantalum capacitors, also known as Ta-capacitors, are a type of electrolytic capacitor that uses tantalum as its anode. These capacitors are constructed using a tantalum metal oxide dielectric layer and two electrodes. The positive electrode is usually formed from an anode of powdered tantalum, whereas the negative electrode is typically formed from a manganese dioxide sintered pellet. Tantalum capacitors are widely used in electronic components due to their small size, good temperature stability, low cost, and high energy density. They can be used in many different applications, including general-purpose decoupling, high frequency oscillator circuits, RF and analog filters, transistor amplifier circuits, and signal processing. Compared to other types of capacitors, tantalum capacitors have lower equivalent series resistance (ESR) and higher capacitance ratings.M39003/09-0005H Application Field and Working Principle:
The M39003/09-0005H is a small, surface-mounted, axial lead tantalum capacitor from Vishay Semiconductor. The device has a working voltage of 50 VDC and a capacitance of 105 µF. It is ideal for use in consumer electronics, telecommunications, automotive lighting, power supplies, and medical devices. The working principle of the M39003/09-0005H is based on the structure of a tantalum capacitor. It consists of a sintered anode pellet made of tantalum and a manganese dioxide cathode, inside of a hermetically sealed metal can. The device has an anode lead that is made of solid, powdered tantalum. The anode lead is in contact with a dielectric layer of tantalum pentoxide. The dielectric layer provides insulation between the two electrodes and thus, allows an electric current to pass through the dielectric when a voltage is applied. An oxide film covers the dielectric layer which acts as an insulating barrier. This oxide film prevents current from flowing directly between the two electrodes and allows the capacitor to maintain its capacitance value.The device also has a cathode lead which is formed from a manganese dioxide pellet. The cathode pellet acts as the negative side of the capacitor and allows electrons to flow from the cathode to the anode during operation. When a voltage is applied across the electrodes, an electric field is created which causes the anode to become positively charged and the cathode to become negatively charged. The electric field between the electrodes is proportional to the applied voltage. As a result, the capacitance value of the device increases with an increase in applied voltage. The M39003/09-0005H is a polar device, as the anode must be connected to a positive potential while the cathode must be connected to a negative potential. Conclusion:
