Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) nominal capacitance with a 500 V rated voltage; capacitance tolerance ±20% (120 Hz, 20°C).
• High‑Temperature Endurance: Rated for operation from −40°C to +105°C with an endurance (load life) of 5000 hours at 105°C under rated ripple current.
• Ripple Current Handling: Specified ripple current of 5.7 A at 120 Hz and 7.98 A at 10 kHz to support high‑frequency and regenerative loads.
• Package & Mounting: Radial can with screw terminals and stud bolt mount (M5 nominal bolt); secure mechanical and electrical connection for industrial systems.
• Durability & Charge/Discharge: Designed to cope with high‑speed charge‑discharge cycles and high‑frequency regenerative voltages typical of AC servomotor and inverter systems.
• Electrical Integrity: Leakage current specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint: High‑voltage design in a smaller size compared with the LNT series; physical dimensions approximately L: 8.0 cm × D: 6.35 cm with seated height up to 3.15 inches.

Typical Applications

• Industrial Inverter Power Supplies: Energy buffering and smoothing for inverter front‑ends and DC link circuits in industrial power systems.
• AC Servomotor Regenerative Circuits: Handling high‑frequency regenerative voltages and supporting energy return in motor drive systems.
• High‑Frequency Charge/Discharge Systems: Components that require rapid charge/discharge capability for pulse or braking applications.
• General Industrial Power Electronics: Bulk energy storage and filtering in general inverter and motor control applications where high voltage and elevated operating temperature are present.

Unique Advantages

• High Voltage Capability: 500 V rating (series rated up to DC525 V) enables use in demanding DC link and high‑voltage power topologies.
• Extended High‑Temperature Life: 5000‑hour load life at 105°C provides predictable performance under elevated thermal stress.
• Designed for High‑Frequency Duty: Ripple current specifications at both 120 Hz and 10 kHz demonstrate suitability for low‑ and high‑frequency ripple environments.
• Robust Mechanical Termination: Screw terminals and M5 stud bolt mounting ensure reliable electrical and mechanical connections in industrial assemblies.
• Low Leakage & Strong Insulation: Leakage current limits and >100 MΩ insulation resistance at DC 500 V support stable DC link operation and safety margins between terminal and bracket.
• Regulatory Compliance: RoHS compliance simplifies use in regulated markets and reduces materials‑related procurement risk.
