Introduction to Tantalum Capacitors

Tantalum capacitors are polarized capacitors which are widely used in electronic circuits.Tantalum is a hard, silvery-grey metal which is chemically and mechanically stable.The M39003/01-2972/HSD consists of tantalum anode, dielectric, cathode and additional components to achieve specified characteristics.It is fixed in a cylindrical case and is classified as an axial leaded component.

M39003/01-2972/HSD Application Field

The M39003/01-2972/HSD is applicable for circuits like high-frequency electronic circuits, filter circuits, timing circuits, switching power supplies, voltage regulator, rectifiers, UPS, high-resolution televisions, mobile communications and many other circuits.

It is suitable for both leaded and SMT applications since its capacitance tolerance is tight and its voltage range is wide.It can operate in temperatures from -55℃ to +125℃ and has a capacitance range of 10µF to 1000µF.

M39003/01-2972/HSD Working Principle

The M39003/01-2972/HSD consists of an anode, dielectric, cathode and additional components.

The anode is made of tantalum metal which has been pre-treated to reduce its surface area and improve the contact zone between the tantalum and the dielectric.The cathode is composed of an internalized coated manganese dioxide electrolyte which forms an electrostatic field between the two.

A capacitor’s capacitance is determined by the area of the plates, the distance between them, and the relative permittivity of the dielectric material between them.In the M39003/01-2972/HSD, the tantalum anode–manganese dioxide electrolyte pairing provides a high capacitance in a small and compact form.

Conclusion

The M39003/01-2972/HSD is an axial leaded component which is widely used in high-frequency electronic circuits, filter circuits, timing circuits, switching power supplies, voltage regulator, rectifiers, UPS, high-resolution televisions, mobile communications and many other circuits.The tantalum anode–manganese dioxide electrolyte pairing gives the M39003/01-2972/HSD a high capacitance in a small package.
