Our range of other capacitors:
Electrolytic capacitors
Electrolytic capacitors are special capacitors with high capacitance that use an electrolyte as a conductive medium. They store electrical energy and are used in power supplies, audio and high-frequency circuits. Due to their polarity, they can only be used in direct current circuits. Common types are aluminum, tantalum and niobium electrolytic capacitors.
Film capacitors
Film capacitors are electrical components for energy storage, consisting of two metal foils or metallized plastic films as electrodes, separated by a dielectric plastic film. They are characterized by high dielectric strength, low losses and a long service life and are used in applications such as power supplies, motor drives and high-frequency technology.
Ceramic capacitors
Ceramic capacitors are electrical components for energy storage and signal filtering. They consist of a ceramic dielectric and metal plates. Their advantages: high stability, low losses, fast charging and discharging times. They are used in electronics, high-frequency technology and power applications - from smartphones to industrial control systems.

What factors influence the service life of SMT tantalum capacitors?
The service life of SMT tantalum capacitors depends on several factors. The correct choice of voltage is crucial - they should be operated with a safety margin of at least 20% below the rated voltage.
Temperature plays a major role: higher ambient temperatures significantly shorten the service life. Mechanical stresses such as vibrations and moisture can also affect performance.
A low ESR and high-quality materials ensure a longer service life. SMT tantalum capacitors from Hongda Capacitors, which are distributed by Rotima AG, are specially developed for high reliability and are particularly suitable for long-lasting electronic products.

What role does ESR play in the selection of an SMT tantalum capacitor?
Equivalent series resistance (ESR) is a decisive factor in the selection of SMT tantalum capacitors, especially in high-frequency and high-current applications.
A low ESR reduces energy losses, improves efficiency and minimizes heating of the component. In power electronics, switching power supplies and audio amplifiers, a low ESR ensures stable voltages and clean signals. In applications that require rapid load changes, capacitors with a low ESR are preferable as they react more quickly to voltage fluctuations.
