Technical Summary and Application Guidelines

Tantalum and OxiCap® capacitors. In circuits which undergo rapid charge or discharge a protective resistor of 1Ω/V is recommended. If this is impossible, a derating factor of up to 70% should be used on tantalum capacitors. OxiCap ® capacitors can be used with derating of 20% minimum. In such situations a higher voltage may be needed than is ...

TECHNICAL PAPER

Tantalum capacitor construction begins with a sintered pellet of powdered tantalum submerged in an acid bath with a DC voltage applied across it. As a result, an oxide layer on tantalum pentoxide quickly forms on the contoured surface of the pellet, the thickness of which is proportional to the voltage applied. This oxide acts as the dielectric ...

Capacitor Guide, your guide to the world of capacitors

A capacitor is able to store energy in an electrostatic field that is generated by a potential difference across the conductors. So when a conductor is subject to a voltage, one plate of the capacitor will collect positive charge while the other will be negatively charged. The ratio of this electric charge and the potential difference (voltage ...
