LGU1K332MELA

The LGU1K332MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, rated 3300 µF at 80 V. It is a radial, can‑style, snap‑in device designed for general‑purpose power applications requiring high capacitance, elevated ripple handling and extended endurance.

Key value is delivered through its 105°C operating capability with 3,000 hours endurance at rated ripple current, wide operating temperature range (‑40°C to 105°C), and measurable ripple and leakage characteristics suitable for demanding power circuits.

Key Features

• Electrical capacity and tolerance — 3300 µF (3.3 mF) nominal capacitance with tolerance of ‑20% to +20% at 120 Hz, 20°C.
• Rated voltage — 80 V DC nominal rating for mid‑voltage power rail applications.
• High‑temperature endurance — Designed for 3000 hours of operation at 105°C when subjected to DC bias plus rated ripple current.
• Ripple current capability — Low‑frequency ripple current 2.76 A at 120 Hz and high‑frequency ripple current 3.174 A at 50 kHz, enabling effective smoothing in switching and linear power stages.
• Loss factor (tan δ) — tan δ = 0.20 measured at 20°C, 120 Hz (for 80 V rating), providing a defined dissipation characteristic for thermal design.
• Leakage current — Specified leakage current of 1540 µA (measured after 5 minutes at 20°C under rated voltage conditions).
• Mechanical and packaging — Radial, can snap‑in package with dimensions φ25 × 45L (D: 2.5 cm × L: 4.5 cm); supplied in tray packing for production handling.
• Environmental compliance — RoHS‑compliant material set.

Typical Applications

• Industrial power supplies — Bulk filtering and energy storage on mid‑voltage rails where 80 V rating, high capacitance and sustained ripple endurance at 105°C are required.
• Power conversion and inverters — Smoothing of DC bus lines in systems that demand high ripple current capability at both low and high frequencies.
• Electromechanical drives and motor control — Energy buffering and decoupling on power rails operating across wide temperature ranges (‑40°C to 105°C).

Unique Advantages

• Extended high‑temperature life: 3000 hours at 105°C under rated ripple conditions reduces the need for overspecifying components for thermal endurance.
• Dual‑frequency ripple performance: Specified ripple currents at 120 Hz and 50 kHz allow designers to account for both mains and switching frequencies in thermal and reliability calculations.
• High capacitance in a compact snap‑in can: 3300 µF in a φ25 × 45L package provides substantial bulk energy storage while maintaining a board‑mountable snap‑in form factor.
• Clear electrical characterization: Defined tan δ and leakage current values simplify thermal budgeting and leakage allowances in system design.
• Production‑ready packaging: Tray packing and mass‑production status support high‑volume assembly and procurement planning.
