LGU2Z821MELB

The LGU2Z821MELB is a Nichicon LGU series snap‑in terminal aluminum electrolytic capacitor designed for general purpose power-electronics applications. It provides 820 µF capacitance at a 180 V rating in a compact φ30 × 30 mm can and is supplied in tray packing for production assembly.

Engineered for robust thermal endurance, this component withstands rated ripple current at 105°C for 3000 hours and offers low-frequency and high-frequency ripple handling to support bulk energy storage and smoothing on medium-voltage rails.

Key Features

• Electrical Performance — 820 µF capacitance with ±20% tolerance (120 Hz, 20°C) and a rated voltage of 180 V, suitable for medium-voltage energy storage and filtering.
• Ripple Current Capability — Rated low-frequency ripple current of 2.04 A (120 Hz) and high-frequency ripple current of 3.06 A (50 kHz) to handle steady and high-frequency ripple loads.
• Loss & Leakage — tanδ (DF) of 0.15 measured at 20°C and 120 Hz, with a specified leakage current of 1150 µA after standard conditioning.
• Thermal Endurance — Specified operating temperature range of −40°C to +105°C and guaranteed endurance of 3000 hours at 105°C under rated ripple/current conditions.
• Mechanical & Mounting — Snap‑in radial can (φ30 × 30L) for secure PCB mounting and robust mechanical retention in assemblies.
• Environmental Compliance — RoHS‑compliant construction consistent with the LGU series directive compliance.

Typical Applications

• Power supply bulk storage — Provides capacitance and ripple handling for smoothing and bulk energy storage on 180 V rails.
• Industrial power electronics — Suited for filtering and decoupling in medium-voltage inverters, converters, and motor drive subsystems where high ripple endurance is required.
• Energy conditioning — Useful for intermediate DC link and energy buffering tasks where sustained performance at elevated temperature is needed.

Unique Advantages

• High-temperature endurance: Rated for 3000 hours at 105°C with specified performance retention, supporting long operational life in elevated-temperature environments.
• Dual-frequency ripple capability: Distinct low- and high-frequency ripple current ratings (2.04 A @120 Hz and 3.06 A @50 kHz) that address both line-frequency and switching-frequency stress.
• Compact snap‑in form factor: φ30 × 30 mm radial can with snap‑in terminals enables secure PCB installation while conserving board area.
• Measurable dielectric performance: tanδ = 0.15 (20°C, 120 Hz) for predictable dissipation behavior in design calculations.
• Regulatory alignment: RoHS‑compliant construction simplifies materials compliance for production programs.
