Vishay / Sprague EP2 High Energy Wet Tantalum Capacitors
Vishay / Sprague EP2 High Energy, Ultra High Capacitance Wet Tantalum Capacitors offer mechanical robustness to meet the needs of military and avionics applications. The EP2 capacitors are based on the SuperTan® technology and deliver a high capacitance (2700µF to 72,000µF) per voltage rating (25VDC to 125VDC). The capacitors feature a standard capacitance tolerance of ±20%, with ±10% tolerance available. These components can be drop-in replacements for competing parts or a higher capacitance alternative in a mechanically equivalent package to reduce component counts, save space, and lower design costs.
Optimized for pulse power and energy hold-up applications in laser guidance, radar, and avionics systems, the EP2 is housed in an all-tantalum, hermetically sealed case for increased reliability. Offering robust mechanical performance, the capacitors feature high vibration (high frequency: 20g; random: 19.64g) and mechanical shock (50g) capabilities. The devices operate over a temperature range of -55°C to +85°C, up to +125°C with voltage derating, and provide a maximum ESR down to 0.017Ω at 1kHz and +25°C. The capacitor is available with tin/lead (Sn/Pb) or RoHS-compliant 100% tin terminations.
