LNU2W332MTEG

The LNU2W332MTEG is a screw-terminal, stud-bolt-mount aluminum electrolytic capacitor designed for high-voltage industrial applications. With a 3300 µF capacitance at a 450 V rating and a 105°C temperature class, it provides bulk energy storage and smoothing in power conversion and inverter circuits.

This part combines high ripple-current capability and long-term endurance with a compact can-style package (φ63.5 × 120 mm), making it suitable for industrial power supplies, inverter/regenerative systems, and other general-purpose high-voltage designs.

Key Features

• Electrical Rating — 3.3 mF (3300 µF) capacitance at 450 V DC with ±20% tolerance; polarized design for DC energy-storage applications.
• High Temperature & Lifetime — Rated for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple conditions.
• High Ripple-Current Capability — Rated ripple current of 15 A at 120 Hz and 21 A at 10 kHz, supporting both low- and high-frequency ripple environments.
• Leakage and Dissipation — Specified leakage current 3650 µA and tangent of loss angle (tan δ) 0.2 for predictable dissipation behavior.
• Mounting & Termination — Stud bolt mount with screw terminals in a radial can configuration; nominal bolt diameter for the φ63.5 size is M5 for secure mechanical attachment.
• Form Factor & Packaging — Compact φ63.5 × 120 mm can (L: 120 mm × D: 63.5 mm) supplied in cardboard packing; brackets supplied separately.
• Regulatory — RoHS compliant and available in mass-production quantities.

Typical Applications

• Industrial Inverters and Motor Drives — Bulk DC-link and regenerative energy handling in inverter circuitry and AC servomotor regeneration where high voltage and high-frequency performance are required.
• Power Supplies and UPS Systems — DC smoothing and energy storage in high-voltage power supplies, benefiting from the 450 V rating and sustained ripple capability.
• High-Speed Charge/Discharge Circuits — Suited for circuits requiring rapid charge/discharge cycling thanks to construction designed to cope with high-speed loading.
• General-Purpose Industrial Electronics — Fits a broad range of industrial power applications that demand robust temperature tolerance and long endurance.

Unique Advantages

• High-voltage capability in a compact can — 450 V rating combined with a φ63.5 × 120 mm package provides high voltage density for constrained enclosures.
• Proven endurance at elevated temperature — 5000 hours life at 105°C under rated ripple conditions helps ensure long-term reliability in thermally demanding systems.
• High ripple-current handling across frequencies — 15 A at 120 Hz and 21 A at 10 kHz support both mains-frequency smoothing and high-frequency switching environments.
• Secure mechanical and electrical connections — Screw-terminals with stud-bolt (M5 nominal for this size) mounting enable robust bolted connections for industrial installations.
• Predictable leakage and dissipation characteristics — Specified leakage current and tan δ provide measurable baseline behavior for system-level thermal and leakage budgeting.
• RoHS compliant and production-ready — Meets RoHS requirements and is listed as mass production, supporting supply continuity for commercial designs.
