LGU2F331MELZ

The LGU2F331MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series designed for general‑purpose power electronics. It delivers 330 µF capacitance at a 315 V rating in a compact radial, can‑snap‑in package (φ22×50 mm) and is produced for mass deployment.

Engineered for elevated operating conditions, this capacitor offers a wide operating temperature range and robust endurance for applications requiring sustained ripple handling and long life at elevated temperatures.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 315 V working voltage and ±20% tolerance (120 Hz, 20°C), suitable for high‑voltage energy storage and filtering.
• Temperature & Endurance — Rated for operation from −25°C to +105°C with a guaranteed endurance of 3000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Low frequency ripple current of 1.33 A at 120 Hz and high frequency ripple current of 1.902 A at 50 kHz, enabling effective AC ripple handling across common power frequencies.
• Leakage & Dissipation — Specified leakage current of 960 µA and tan δ measured at 20°C, 120 Hz to characterize dissipation (loss) performance.
• Mechanical & Mounting — Snap‑in terminal radial can (φ22×50L) for secure PCB mounting and tray packing for production handling.
• Compliance — RoHS‑compliant construction to meet regulatory requirements for restricted substances.

Typical Applications

• Power supply smoothing — Bulk filtering and energy storage in high‑voltage power supplies where 315 V rating and substantial capacitance are required.
• DC‑link and inverter stages — DC‑link smoothing for power converters and inverters that benefit from the capacitor’s rated ripple current and 105°C endurance.
• Industrial drives and motor control — Energy buffering and ripple reduction in motor drive electronics that operate across elevated temperatures.

Unique Advantages

• High‑temperature endurance: 3000 hours at 105°C under rated ripple current provides predictable lifetime behavior in thermally demanding installations.
• Designed for real ripple loads: Specified ripple current at both 120 Hz and 50 kHz supports performance across low and high frequency switching environments.
• Compact, robust mounting: Snap‑in radial can (φ22×50 mm) offers secure PCB attachment and straightforward mechanical integration for production assemblies.
• Clear electrical characterization: Leakage current and tan δ values are specified to support design margining and thermal management decisions.
• Production readiness: Tray packing and mass production status facilitate volume procurement and repeatable assembly processes.
• Regulatory compliance: RoHS compliance supports deployment in regions and products requiring restricted‑substance adherence.
