Additional Details

This capacitor has a standard tolerance rating, typically ±20%. The operating temperature range typically spans from -55°C to +125°C. The ESR (Equivalent Series Resistance) is a key parameter to consider, especially in high-frequency applications, and this information can be found on the product datasheet. Tantalum capacitors are polarized devices, requiring careful attention to polarity during circuit design and assembly to prevent damage or failure. It is crucial to consult the manufacturer's datasheet for detailed specifications, including ESR, ripple current rating, and leakage current to ensure proper application and reliable performance. The capacitance is specified at 120Hz.
