Built to the LNU series specifications, this part delivers long operational life under elevated temperature and ripple stress, with RoHS compliance for regulated manufacturing environments.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 450 V DC with ±20% tolerance (120 Hz, 20°C).
• High‑Temperature Endurance — Rated for operation up to 105°C with a load life of 5000 hours at 105°C when subjected to rated ripple current and DC bias.
• Screw Terminal Mounting — Radial can construction with screw terminals for secure, high‑current connections suitable for power modules and bus capacitors.
• High Ripple Capability — Ripple current ratings of 15.4 A at 120 Hz and 21.56 A at 10 kHz to support high‑frequency regenerative and inverter environments.
• Polarized Electrolytic — Polarized construction for DC bulk energy storage in power conversion circuits.
• Mechanical & Size — Can dimensions: φ76.2 × 105 mm (length 10.5 cm × diameter 7.62 cm); M5 nominal bolt for terminals and separate bracket supply noted.
• Leakage & Insulation — Leakage current after 5 minutes: ≤ 3√(C·V) µA or 5 mA (whichever is smaller) at 20°C; insulation resistance > 100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliant — Complies with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk DC link and energy storage for inverter stages, benefiting from the high voltage rating and high ripple current capability.
• Servo Drives & Motor Control — Filtering and regenerative energy buffering in AC servomotor and drive systems where frequent charge/discharge cycles occur.
• Power Supplies — Smoothing and hold‑up in high‑voltage industrial power supplies and UPS modules that require long life at elevated temperatures.
• High‑Frequency Regenerative Circuits — Supports high‑speed charge/discharge and regenerative voltages in applications operating at kHz switching frequencies.

Unique Advantages

• Long Operational Life: 5000 hours at 105°C under rated ripple current ensures predictable endurance for demanding industrial applications.
• High Ripple Handling: Rated ripple currents at both 120 Hz and 10 kHz provide design flexibility across low and high switching‑frequency power systems.
• Secure Screw‑Terminal Connectivity: Radial can with screw terminals and M5 nominal bolt support robust mechanical and electrical connections for high‑current paths.
• Wide Operating Temperature Range: –40°C to +105°C operation enables deployment across varied industrial environments without derating beyond spec limits.
• Measurable Leakage & Insulation Specs: Clear leakage current limits and >100 MΩ insulation resistance specification aid in predictable system behavior and safety margins.
• Regulatory Compliance: RoHS compliance simplifies integration into modern, environmentally constrained manufacturing processes.
