A surface-mount type (SMD) tantalum capacitor—D-type tantalum capacitor 2

II. Features

1. High capacity and small size: Tantalum capacitors feature high specific capacity, meaning they can provide greater capacitance within the same volume.diode

2. High Reliability: Tantalum capacitors generally have a long service life and high stability.

3. Wide operating temperature range: Capable of functioning within a broad temperature range, suitable for various environmental conditions.diode

4. Polarity: Tantalum capacitors are polarized, and correct installation orientation is crucial for their proper operation.

III. Working Principle diode

The working principle of Type D tantalum capacitors is based on the fundamental operation of the AD9883AKSTZ-110 capacitor. When the circuit is connected to a power source, charges accumulate across the capacitor terminals, creating a potential difference. The charge storage in tantalum capacitors relies on the electric field between the anode (made of tantalum powder) and the cathode (a conductive layer on the tantalum dioxide layer). Due to the high dielectric constant of the tantalum dioxide layer, tantalum capacitors can store significant amounts of charge within a compact volume.diode
