Good Stability
The stability of CL21-film capacitors is significantly better than that of electrolytic capacitors and ceramic capacitors. They are less likely to experience performance changes due to long usage or environmental changes. High-quality CL21-film capacitors can function without issues for 5-10 years.
Self-Healing Properties
One distinctive feature of CL21-film capacitors is their self-healing properties, which can be categorized into discharge self-healing and electrochemical self-healing. This means that many times, if a film capacitor is damaged, it does not need to be replaced as it can self-heal. This reduces the cost of capacitor replacement, maintenance, troubleshooting, and minimizes downtime due to machine failures.
Low Leakage Current
CL21-film capacitors generally have high insulation strength and low leakage current due to their insulating film. This effectively reduces circuit power consumption and noise, with minimal internal temperature rise and heat generation.
Power Supply Systems
Ideal for filtering and smoothing power supplies to reduce ripple and noise while simultaneously decreasing ripple voltage spikes and noise induced into electrical circuits.
