Additional Details

The T494A225K020AT comes in a standard EIA case size (e.g., 1206 or 0805). The operating temperature range is typically -55°C to +125°C. The dissipation factor (DF) and equivalent series resistance (ESR) are important parameters to consider for high-frequency applications. The datasheet should be consulted for exact specifications, including the ripple current rating and other performance characteristics. Tantalum capacitors are polarized devices, so proper orientation is critical.
