• High‑Temperature Endurance — Designed for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple current.
• Mounting & Package — Stud bolt mount with radial can and screw terminals for robust mechanical and electrical connections; nominal bolt size and bracket details provided in series documentation.
• Ripple Current Handling — Supports 6.6 A ripple at 120 Hz and 9.24 A at 10 kHz, suitable for high ripple applications and regenerative circuits.
• Charge‑Discharge Durability — Series validated for high‑speed charge/discharge loading and extended charge/discharge endurance.
• Polarized Electrolytic Design — Polarized capacitor optimized for DC bus and inverter power stages with ±20% capacitance tolerance.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Series Profile — Smaller physical footprint compared to the LNT series; part dimensions: length 9.0 cm × diameter 6.35 cm and seated height up to 3.543 inch.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and DC bus smoothing in inverter power supplies where high voltage and long life are required.
• Inverter Systems — Energy buffering and ripple suppression for general inverters operating with regenerative or high‑frequency loads.
• AC Servo Drives — Handling high‑frequency regenerative voltage and repeated charge/discharge cycles in servomotor drives.
• High‑Frequency Regenerative Circuits — Suited for applications that require reliable performance under high ripple and frequent energy recovery events.

Unique Advantages

• High‑Voltage Capability: 500 V rated (series up to DC525 V) enables use on elevated DC bus rails without parallel stacking.
• Long Life at Elevated Temperature: 5000‑hour load life at 105°C under rated ripple current supports demanding industrial duty cycles.
• Robust Ripple Handling: Specified ripple currents of 6.6 A (120 Hz) and 9.24 A (10 kHz) address both low‑ and high‑frequency power environments.
• Designed for Charge/Discharge Stress: Constructed to cope with high‑speed charge/discharge loading and endurance test criteria defined in the series datasheet.
• Secure Mechanical Attachment: Stud bolt mount and screw terminals provide dependable connections for high‑current, vibration‑prone installations.
• Regulatory Compliance: RoHS conformity for use in markets requiring restricted‑substance compliance.
