LGU2Z331MELZ

The LGU2Z331MELZ from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGU series, rated for 330 µF at 180 V with a ±20% tolerance. Designed as a 105°C standard part with snap-in mounting and radial can packaging, it targets general-purpose electronic equipment requiring high-temperature endurance and stable ripple handling.

Key value comes from its long endurance (3,000 hours at 105°C), significant low- and high-frequency ripple capability, and compact φ22 × 25L snap-in package supplied in tray packing for mass production needs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 180 V and ±20% tolerance at 120 Hz, 20°C.
• High-Temperature Endurance — Rated for operation from −40°C to 105°C and specified to withstand 3,000 hours of rated ripple current at 105°C.
• Ripple Current Handling — Low-frequency ripple current of 1,200 mA at 120 Hz and high-frequency ripple current of 1,800 mA at 50 kHz for robust power conditioning performance.
• Loss and Leakage — Specified tangent of loss angle (tan δ) of 0.15 and a leakage current of 730 µA, allowing predictable dissipation and standby characteristics.
• Package & Mounting — Snap-in terminal, radial can (snap-in) mounting in a compact φ22 × 25L package (size L: 2.5 × D: 2.2 cm); supplied in tray packing suitable for production lines.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronic equipment — Used where a 180 V, 330 µF electrolytic capacitor with 105°C endurance and snap-in mounting is specified.
• Power filtering and smoothing — Applied in designs that require specified ripple-current handling at both low (120 Hz) and high (50 kHz) frequencies.
• Mass-production systems — Tray packing and snap-in mounting support automated assembly for volume production runs.

Unique Advantages

• Long high-temperature life: Specified 3,000 hours at 105°C under rated ripple conditions, supporting reliability in elevated-temperature environments.
• Dual-frequency ripple capability: Defined ripple current ratings at 120 Hz (1.2 A) and 50 kHz (1.8 A) provide predictable performance across common power-frequency and switching-frequency conditions.
• Compact snap-in form factor: φ22 × 25L radial can with snap-in terminals offers a space-efficient solution for chassis- or board-mounted power components.
• Predictable electrical characteristics: Specified tan δ (0.15) and measured leakage current (730 µA) allow accurate thermal and leakage budgeting in designs.
• Production-ready packaging: Tray packing and mass-production availability simplify procurement and assembly planning.
• RoHS compliant: Conforms to RoHS requirements for regulated substances.
