We are using this one. High-ripple-resistant electrolytic capacitor Previously, many issues have arisen for users. Therefore, to make better use of this product, it’s essential to understand some of its key technical aspects. First and foremost, you should be aware that high-ripple-resistant electrolytic capacitors employ extremely fine tantalum powder. The dielectric constant ε of the tantalum oxide film is 17 times higher than that of the aluminum oxide film, which means that tantalum capacitors have a significantly higher capacitance per unit volume. This product boasts a wide operating humidity range. Typically, tantalum electrolytic capacitors can function normally within a temperature range of -50℃ to 100℃. Although high-ripple-resistant electrolytic capacitors can also operate within this temperature range, their electrical performance falls far short of that of tantalum electrolytic capacitors. The tantalum oxide film used in electrolytic capacitors with high edge resistance and low leakage current not only exhibits excellent corrosion resistance but also maintains outstanding performance over the long term. Additionally, there’s another crucial point: when the operating frequency is high, capacitors with good impedance-frequency characteristics experience a noticeable drop in capacitance and an increase in dissipation factor (tan δ). However, solid-state electrolytic capacitors can operate reliably at frequencies above 50 kHz. As the frequency rises, the capacitance of tantalum capacitors does decrease—but the reduction is relatively minor. According to available data, at 10 kHz, the capacitance drop is less than 20%, whereas the capacitance of aluminum electrolytic capacitors drops by as much as 40%.
High-ripple-resistant electrolytic capacitor Tantalum oxide films boast high reliability and stable performance. Moreover, since the tantalum anode substrate Ta2O5 is resistant to both strong acids and strong bases, it allows the use of solid or liquid electrolytes with low resistivity that contain acidic components. As a result, the equivalent series resistance (ESR) of these tantalum electrolytic capacitors is lower than that of aluminum electrolytic capacitors, and they exhibit excellent temperature stability. In particular, aluminum electrolytic capacitors tend to have larger volumes, higher series resistance, greater inductive reactance, and greater sensitivity to temperature changes. Therefore, they are more suitable for applications with relatively small temperature variations and moderate operating frequencies (not exceeding 25 kHz), making them ideal for low-frequency filtering. Furthermore, the capacitance of tantalum electrolytic capacitors remains essentially independent of their operating voltage, ensuring stable operation even under conditions of voltage fluctuations.
