What is a tantalum capacitor?

Tantalum capacitors use tantalum metal and solid manganese dioxide electrolyte, providing high capacitance in a compact size. Normal electrolytic capacitors, often aluminum-based with liquid electrolyte, offer a wider range of capacitance. Tantalum capacitors are polarized, unlike some electrolytic capacitors.

Why are tantalum capacitors so expensive?

Tantalum capacitors are relatively expensive even when supply and demand are balanced. Not too long ago prices went sky high due to a shortage in raw materials. There are numerous reports of tantalum capacitors spontaneously combusting. I haven’t read into this any further, but I take it some forum members can elaborate on this.

Where can I buy a tantalum refractory capacitor?

Admat, Inc., located in Norristop, PA, distributes tantalum hybrid capacitors as well as capacitor lead sealing. It also offers other refractory metal products and parts.

Where are Vishay tantalum capacitors produced?

Vishay's tantalum capacitors are produced in the Miharu plant (Japan) following the acquisition of the tantalum manufacturing plant from Holy Stone Polytech Co. Ltd.
