Precautions for High-Ripple-Current Electrolytic Capacitors

20 Oct,2022

What are the precautions for high-ripple-current electrolytic capacitors? I’m sure many people still aren’t clear about these issues. So today, I’d like to share some knowledge related to them with you all! I hope this will be of real help to those concerned.

What are high-ripple-resistant electrolytic capacitors like? What are their characteristics?

25 Oct,2022

Due to the development of high-ripple-resistant electrolytic capacitors, this traditional electrolyte can no longer meet the requirements. Consequently, many new electrolytes have been developed to broaden the operating temperature range of capacitors (e.g., from -55°C to 33.354.125°C). The formulation principle behind these new electrolytes is to mix two solvents in a complementary manner. Two weak acids are used to provide the two required anionic groups. An alkali, such as an organic amine, is added to adjust the electrolyte’s pH and flashover voltage, thereby modifying its resistivity. Additives that enhance the electrolyte’s properties include phosphoric acid or its salts, which prevent hydration of the aluminum oxide film; diphenyl nitrate, which absorbs hydrogen gas; and ethylene oxide, which increases the electrolyte’s flashover voltage.

How do we test high-ripple-resistant electrolytic capacitors for leakage? And how should we handle any detected faults?

High-ripple-resistant electrolytic capacitors use an aluminum cylinder as the negative electrode, contain a liquid electrolyte inside, and have a bent aluminum strip inserted as the positive electrode. They also require DC voltage treatment to form an oxide film on the anode plate, which serves as the dielectric. These capacitors are characterized by large capacitance, high leakage current, poor stability, and polarity sensitivity; they are suitable for power filters or low-frequency circuits. When using them, be sure not to connect the positive and negative terminals incorrectly.
