The steady-state and dynamic reliability of tantalum capacitors are influenced by several factors that can be controlled by the circuit design engineer. Key factors include voltage derating, ripple current, voltage conditions, maximum operating temperature, and circuit impedance.

Tantalum capacitors are known for their low electrical leakage (high leakage resistance) and ability to retain a charge over extended periods. They perform well in hot environments, withstanding temperatures up to 125°C, which makes them superior to standard aluminum electrolytic capacitors. However, tantalum capacitors can be relatively expensive, especially the military-grade versions. They are not particularly tolerant of heavy charge and discharge currents, particularly repetitive ones, and their effective series resistance (ESR) is higher compared to ceramic or aluminum electrolytic capacitors.

Since 1997, Kingtronics has been producing high-quality tantalum capacitors, including:

• Dipped Tantalum Capacitors (through-hole)

• General Purpose Chip Tantalum Capacitors (surface mount)

• Low-ESR Chip Tantalum Capacitors (surface mount)

Our tantalum capacitors are designed for a wide range of applications, offering high reliability and performance in demanding environments.
