The capacitance range of this model is 0.1uF to 2.2uF, so it is suitable for various kinds of circuit designs with different voltage requirements. Its operating temperature range is -55°C to +125°C, with a highly reliable temperature range of -55°C to +105°C, so it can work under harsh weather conditions.

Working Principle

M39003/01-7007 Tantalum capacitor belongs to an electrolytic capacitor, which contains two electrodes and an electrolytic substance. The anode is made of a porous sintered tantalum base and a layer of oxide film with electrons. The cathode is made of aluminum plate with oxidizing layer and electrolyte. Under the action of the electric field of the oxide film and the electrolyte, the electrons of the anode move to the cathode. This process produces a capacitance, which is the main function of the capacitor.

The oxide film of the M39003/01-7007 is a dielectric material, and its performance determines the performance of the capacitor. The dielectric is made of tantalum oxide, which can prevent the internal electrons from replenishing, and its electric field intensity can also be maintained at a certain value, providing a stable capacitance. In addition, its small size and light weight make it an ideal choice for miniaturized embedded systems.
