LGU1K332MELB

The LGU1K332MELB is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers 3300 µF at 80 V in a radial snap‑in can designed for general‑purpose power applications requiring high ripple handling and elevated temperature endurance.

Key value comes from its rated performance at 105°C (3000 h endurance), combined ripple current capability at both low and high frequencies, RoHS compliance, and tray packaging for production handling.

Key Features

• Capacitance & Voltage – 3300 µF (3.3 mF) nominal capacitance with ±20% tolerance at 120 Hz, rated for 80 V operation.
• High‑temperature Endurance – Specified to withstand 3000 hours of rated ripple current at 105°C per the LGU series endurance test.
• Snap‑In Terminal / Package – Radial, can-style snap‑in mounting for secure PCB retention and high-current connections.
• Ripple Current Capability – Low‑frequency ripple current 2.78 A at 120 Hz and high‑frequency ripple current 3.197 A at 50 kHz (part-specific values).
• Loss and Leakage – Dissipation factor (tan δ) max 0.20 (measured at 20°C, 120 Hz) and measured leakage current listed as 1540 µA.
• Operating Temperature Range – Rated for −40°C to +105°C for a wide range of environmental conditions.
• Physical Size & Packaging – Compact φ30 × 35 mm can (D × L) supplied in tray packing; part is in mass production.
• RoHS Compliant – Manufactured in compliance with RoHS directives.

Typical Applications

• Power supply bulk smoothing – Provides bulk energy storage and smoothing for general‑purpose power supplies where 80 V rating and 3300 µF capacitance are required.
• DC link and power conversion – Suited for DC link smoothing and intermediate storage in power conversion circuits that demand elevated ripple handling and high operating temperature endurance.
• Industrial power electronics – Applicable in industrial equipment requiring polarized snap‑in capacitors with reliable performance at up to 105°C and extended life under ripple stress.
• General‑purpose energy storage – Useful for designs that need a compact, high‑capacitance radial can with mass‑production availability and tray packing for assembly.

Unique Advantages

• Long endurance at elevated temperature – Endurance rating of 3000 hours at 105°C under rated ripple current delivers predictable lifetime behavior in hot operating environments.
• High ripple capability across frequencies – Specified ripple currents at 120 Hz and 50 kHz (2.78 A and 3.197 A respectively) enable reliable performance in both low‑ and high‑frequency circuits.
• Engineered for robust board mounting – Snap‑in terminal and radial can package provide secure mechanical retention and high current handling for through‑hole assemblies.
• Compact, high capacitance – 3300 µF in a φ30 × 35 mm can offers significant energy density for designs constrained by board space.
• Production‑friendly packaging – Tray packing and mass production status support repeatable procurement and assembly workflows.
• Standards‑based electrical characteristics – Measured tan δ (0.20 at 20°C, 120 Hz) and documented leakage behavior provide clear parameters for design margining.
