Tantalum Capacitors

Tantalum capacitors are a type of capacitor that offers numerous advantages over traditional electrolytic capacitors. These capacitors are widely used in a variety of applications and are often utilized to aid in filtering and electrical noise reduction in various devices. The M39003/01-8091/TR is a type of surface mounted tantalum capacitor that offers low ESR, high capacitance values, and low leakage current.

Application Field

M39003/01-8091/TR tantalum capacitors are becoming increasingly popular due to their high capacitance values, small size, low profile, and low inductance. They are used in many consumer and industrial electronic applications such as portable medical equipment, electrocardiograms, ECGs, and LED lighting products. Moreover, they are also used in mobile phones, digital signal processors, military and space electronics, automotive ECUs, and many more applications.

Working Principle

Tantalum capacitors are unique capacitors that operate unlike many other types of capacitors in that they use a solid tantalum metal as their dielectric. A solid tantalum capacitor uses an anode of pure tantalum metal, typically cylindrical or semicircular, and a cathode of an oxide of tantalum that is applied to the surface of the anode. A thin layer of non-conductive material such as silicon nitride is then applied to the cathode to provide insulation. The anode and cathode are separated by a dielectric layer, which is typically tantalum dioxide, that prevents a short circuit between the two.

Current flow across the capacitor is determined by the size, form, and construction of the capacitor. When a voltage is applied to the tantalum capacitor, a charge builds up on the anode and is stored in the dielectric layer. This charge can then be discharged when the voltage is removed. The amount of charge that is stored in the dielectric layer is determined by the capacitance of the capacitor. Tantalum capacitors are able to store a great amount of charge in a relatively small package due to their chemical construction.

M39003/01-8091/TR tantalum capacitors offer excellent electrical characteristics and are used in many applications. Their low profile and high capacitance values make them ideal for use in portable medical device and automotive ECUs. Additionally, their low ESR and low leakage current make them a great option for filtering and noise reduction in a variety of devices.

Conclusion

The M39003/01-8091/TR tantalum capacitor is a great solution for many electronic applications. Its small size, low profile, and high capacitance make it an ideal choice for use in many consumer and industrial applications. Its low ESR and low leakage current make it an ideal candidate for Filtering and noise reduction in devices. Tantalum capacitors offer superior electrical characteristics and are being used more and more in applications where traditional electrolytic capacitors are not capable.
