Tantalum Processed Parts

Small in Size

Because tantalum capacitors use tantalum powder with very fine particles, and the dielectric constant of the tantalum oxide film is 17 higher than that of the aluminum oxide film, the tantalum capacitor has a large capacitance per unit volume.

Wide Operating Temperature Range

Generally, tantalum electrolytic capacitors can work normally at a temperature of -50°C to 100°C. Although aluminum electrolytic capacitors can also work in this range, the electrical performance is far inferior to tantalum electrolytic capacitors.

Long Service Life, High Insulation Resistance, Low Leakage Current

The tantalum oxide film medium in the tantalum electrolytic capacitor is not only resistant to corrosion but also can maintain good performance for a long time.

Good Impedance Frequency Characteristics

For capacitors with poor frequency characteristics, the capacitance decreases significantly when the operating frequency is high, and the loss also increases sharply. But solid tantalum electrolytic capacitors can work above 50kHz. With the increase in frequency, tantalum capacitors will also show a decrease in capacity, but the decrease is relatively small.

High Reliability

Tantalum oxide film has stable chemical properties, and because Ta2O5, the tantalum anode substrate, can withstand strong acids and bases. Therefore, it can use solid electrolytes or liquid electrolytes with low acid resistivity, which makes the loss of tantalum electrolytic capacitors less than that of aluminum electrolytic capacitors, and the temperature stability is good.
