Tantalum foil capacitors

Tantalum foil capacitors are a central electronic component in consumer electronics (hi-fi devices, computers, TV-sets, etc.) as well as in modern communication equipment, such as cellular phones, and vehicle construction.The centerpiece of a capacitor are porous sintered compacts made of fine tantalum powder, which have to be sintered under high vacuum. To connect this centerpiece with exterior contacts, lead-in wires made of tantalum are required.
