Our Samwha Electric Capacitors Portfolio
Single Cell & Module Green Cap
Electric Double Layer Capacitors (EDLC), also referred to as „Supercapacitors“, are next generation energy storage devices with excellent cycle characteristics. They are the capacitors with the highest energy density and close to gap to batteries.
Conductive Polymer Hybrid
Through using a combination of conductive polymer electric materials and liquid electrolytes as electrolyte, conductive polymer hybrid aluminium electrolytic capacitors merge the best of both worlds.
Conductive Polymer
Conductive polymer aluminium electrolytic capacitors use a highly electric conductive polymere as its electrolyte. As a result, the internal resistance ESR is lower and higher currents can be held up.
Surface Mount
Surface mount aluminium electrolytic capacitors (SMD / SMT types) are designed for surface mounting on printed circuit boards (PCB), enabling significant system cost savings.
Miniature
The miniature aluminium electrolytic capacitor line of Samwha consists of radial type capacitors with lead wires, which can be formed according to the customer’s requirements. They are available in terminal and small sizes.
Large
The large aluminium electrolytic capacitor series of Samwha are available as snap-in, screw, and special types for specific applications.
Electric Double Layer Capacitors (EDLC), also referred to as “Supercapacitors”, are next generation energy storage devices with excellent cycle characteristics. Through having the highest energy density among all capacitors, they close the gap between batteries and common capacitors. In order to reach higher voltages, single cells can be connected in series or parallel, resulting in supercapacitor modules. Despite the technology being around for some time, new application fields arise on a daily basis, enabling EDLCs a promising future.

Conductive polymer aluminium electrolytic capacitors use a highly electric conductive polymere as its electrolyte. The material composition enables the capacitors to have lower internal resistance ESR and being able to withstand higher currents. Due to the high polymer percentage, the electrolyte contains hardly any liquid and has therefore a low risk of drying out. As the polymer adapts in high temperatures, the capacitors’ life is not affected by temperature, which results in longer a lifetime. Due to being suitable for high frequency applications, the capacitors are ideal for digital circuits.
Features / Advantages:
- Low impedance at high frequencies (10kHz~10MHz)
- Can withstand high ripple current due to reduced ESR
- Excellent noise-absorbent characteristics
- Very stable capacitance, impedance, and ESR against temperature
- Longer lifetime and high reliability
Possible Application Examples:
- Automotive
- Smartphones and connected devices
- TVs and flat screens
- PCs and notebooks
- Digital cameras
