Electrolytic capacitors
A tantalum capacitor is an electrolytic capacitor that uses tantalum as the anode material. This type of capacitor is characterized by high capacitance density, low leakage currents and stable electrical properties. They are often used in DC circuits, for decoupling, filtering and energy storage.
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.

Structure and function of SMT electrolytic capacitors
SMT electrolytic capacitors consist of an aluminum or tantalum anode, an electrolyte liquid and a cathode. The aluminium version uses an oxidized layer as a dielectric, while tantalum capacitors work with a solid electrolyte. This design enables high capacities in a compact size.
Thanks to SMT technology (Surface Mount Technology), the capacitors are soldered directly onto the circuit board. This improves heat dissipation and reduces electrical losses. Thanks to their low impedance and long service life, they are ideal for applications in power supply units, control systems and high-frequency circuits. Rotima AG, as a distributor of Hongda Capacitors, offers reliable solutions for demanding electronics projects.

What are the advantages of SMT electrolytic capacitors over wired capacitors?
SMT electrolytic capacitors have several advantages over wired versions. As they are soldered directly onto the PCB, they enable automated assembly and reduce assembly costs. Their compact design saves space, which is particularly advantageous for modern, miniaturized electronics. They also offer better heat dissipation and lower parasitic inductance, making them ideal for high-frequency applications.
Wired electrolytic capacitors often have a larger design and must be soldered into the circuit board manually or by special machines. This increases the space required and makes production more expensive. SMT variants, on the other hand, can be processed more quickly and offer greater mechanical stability as they sit flat on the PCB and do not have sensitive connecting wires. These advantages make SMT electrolytic capacitors the preferred choice for modern electronics in industrial, automotive and consumer electronics.

Why are SMT electrolytic capacitors so important for voltage stabilization?
SMT electrolytic capacitors play a decisive role in the voltage stabilization of electronic circuits. They can store electrical charge and compensate for voltage fluctuations. This is particularly important in DC/DC converters, power supplies and microprocessor circuits, where constant voltages are essential for operation.
Thanks to their high capacitance and low impedance, they reduce interference caused by sudden load changes. Without such stabilization, sensitive components such as ICs or sensors could be damaged by voltage spikes or malfunctions could occur. They also improve the efficiency of circuits by smoothing out unwanted alternating voltage components (ripple).
In high-frequency applications, they help to minimize signal noise, which improves the performance and reliability of electronic systems. This is why SMT electrolytic capacitors can be found in almost all modern electronics.

How does impedance affect the performance of SMT electrolytic capacitors?
The impedance of an SMT electrolytic capacitor is a decisive factor for its performance. It is made up of the ohmic resistance (ESR), the inductance (ESL) and the capacitance. A low impedance means that the capacitor can conduct current more efficiently, which is particularly important in high-frequency applications.
In switching power supplies and DC/DC converters, capacitors with low impedance reduce the voltage ripple, which improves the stability of the output voltage.
If the impedance is too high, the capacitor cannot effectively compensate for current peaks, which can lead to interference or even damage to the circuit. Especially in power electronics, low-ESR capacitors are therefore often used to efficiently filter high currents. Manufacturers such as Hongda Capacitors offer SMT electrolytic capacitors with optimized impedance for various applications.

What is the service life of SMT electrolytic capacitors and what factors influence it?
The service life of SMT electrolytic capacitors depends on several factors. Temperature, voltage, ripple current and humidity are particularly important. Typical aluminum SMT capacitors have a service life of 1,000 to 10,000 hours at high operating temperatures (e.g. 105°C).
At lower temperatures, however, the service life can be significantly extended. Tantalum capacitors are more durable and often reach several decades if they are operated within their specifications. Exceeding the rated voltage or excessive temperatures accelerate the ageing process and can lead to premature failure.
In applications with high ripple current, care should be taken to ensure that the capacitor has an appropriate load capacity. Hongda Capacitors develops SMT electrolytic capacitors with a long service life, which are suitable for demanding applications where high reliability is required.

What are the differences between aluminum and tantalum SMT electrolytic capacitors?
SMT electrolytic capacitors are available in aluminium and tantalum versions, each optimized for different applications. Aluminum SMT capacitors offer high capacitance at a low price and are ideal for general applications in power supplies, audio amplifiers or control electronics. However, they have limited dielectric strength and are more susceptible to leakage currents.
Tantalum capacitors, on the other hand, are more compact, have higher voltage stability and lower leakage currents. They are particularly suitable for applications with precise voltage regulation, such as in microprocessor circuits or medical devices. However, they are more expensive and more sensitive to overvoltages, which can lead to failures. The choice between aluminum and tantalum capacitors therefore depends on the capacitance, dielectric strength and cost requirements of the application in question.
