Kampala High Temperature Electrolytic Capacitor Factory

What is the maximum operating temperature of a solid electrolytic capacitor?

For decades the maximum recommended operating temperature of solid electrolytic capacitors was 125°C. Responding to needs in the automotive and downhole drilling industries passive component manufacturers developed surface mount tantalum capacitors rated at 150°C in 2002-2003.

What temperature can a tantalum capacitor be rated at?

Responding to needs in the automotive and downhole drilling industries passive component manufacturers developed surface mount tantalum capacitors rated at 150°C in 2002-2003. Since that time the industry has introduced high temperature capable tantalum capacitors generally in 25°C increments roughly every four years.

Which materials are used in solid electrolytic capacitors?

The primary challenges encountered when developing solid electrolytic capacitors with high temperature capabilities are associated with the carbon, silver and epoxy encapsulant materials used in conventional surface mount tantalum capacitors. Capacitor manufacturers have taken different paths to overcome these challenges.

Does silver migration cause leakage failures in solid electrolytic capacitors?

The results provide further strong evidence that silver migration is a potential cause of leakage failures in solid electrolytic capacitors during very high temperature unbiased life tests. The use of an electroplated metal layer provides other advantages to the reliability of a capacitor in a high temperature environment.

What is a low ESR capacitor?

Low ESR levels provide very high ripple current capability Miniaturized, high CV-product per unit volume Polarized aluminum electrolytic capacitors, non-solid electrolyte Axial leads, cylindrical aluminum case, insulated with a bluesleeve Taped versions up to case Ø 15 mm x 30 mm available for automatic insertion

How often do tantalum capacitors come out?

Since that time the industry has introduced high temperature capable tantalum capacitors generally in 25°C increments roughly every four years. Today multiple manufacturers have products rated at 230°C poised for market release.
