• High Ripple Current — Designed for high ripple loading with ripple current ratings of 19.9 A at 120 Hz and 27.86 A at 100 kHz to support rapid charge–discharge cycles.
• Long Load Life — Load life of 5000 hours at 85°C under rated ripple current and DC bias; endurance criteria include capacitance change within ±20% and leakage current within specified limits after test.
• Package & Mounting — Screw terminal, radial can package (can with screw terminals) for robust, secure connections in industrial assemblies.
• Operating Temperature — Rated for operation from –40°C to +85°C, suitable for typical industrial environments.
• Electrical Robustness — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Compact Footprint — Smaller‑sized design with physical dimensions L: 12.0 cm × D: 7.62 cm and seated height up to 4.724 in, enabling space‑efficient power designs.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Energy storage and smoothing in high‑voltage power supply rails for industrial equipment.
• Inverter Circuitry — Bulk capacitance and ripple handling for general inverter systems and converter front‑ends.
• AC Servomotor Regeneration — High‑frequency regenerative voltage support in AC servomotor drives, where charge–discharge endurance is required.
• High‑Frequency Power Systems — Systems requiring repeated high‑speed charge/discharge cycles and elevated ripple capacity at both low and high frequencies.

Unique Advantages

• High ripple capability: Specified ripple currents of 19.9 A (120 Hz) and 27.86 A (100 kHz) let designs handle heavy AC loading and high‑speed switching environments.
• Extended service life under load: 5000 hours at 85°C with rated ripple and DC bias ensures predictable long‑term performance in continuous industrial operation.
• Robust electrical safety margins: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V, 1 minute voltage proof between terminal and bracket provide durability for high‑voltage assemblies.
• Compact, secure mounting: Screw‑terminal radial can simplifies installation and provides mechanically secure connections for rugged applications.
• Wide ambient tolerance: −40°C to +85°C operating range supports diverse industrial environments without derating beyond published limits.
• Standards‑oriented design: Capacitance tolerance, leakage current limits, and endurance criteria are defined per the datasheet specifications to facilitate engineering verification.
