AI Overview
Key Features and Advantages
- Environmental Protection: The hermetic seal ensures stability and long-term reliability by isolating the internal structure from external humidity and contaminants.
- High Performance: These capacitors offer low Equivalent Series Resistance (ESR), low DC leakage, and high volumetric energy density, often reaching up to 2 Joules per cubic centimeter.
- High Temperature & Reliability: They are rated for high-temperature operations, with some series, such as KYOCERA AVX THH and RFECHO CA38MH, capable of operating up to 230°C and 200°C, respectively.
- Robustness: Tested to withstand high shock (50g) and vibration (20G).
Common Applications
Leading Manufacturers and Series
- Vishay / Sprague: EP2 High Energy Wet Tantalum Capacitors.
- KYOCERA AVX: THH 230°C Hermetic Series and Stacked TCH.
- RFECHO: CA38H and CAK38M Series.
