LGG2W151MELA30

The LGG2W151MELA30 is a 150 µF, 450 V aluminum electrolytic capacitor from Nichicon’s LGG series, designed as a snap‑in terminal, radial can package for general‑purpose power applications. It combines high voltage capability with a compact φ25 × 30 mm case and is targeted at equipment downsizing where reliable DC filter and energy storage are required.

Key performance characteristics include a ±20% capacitance tolerance, a low loss tangent (tan δ = 0.20 at 20°C, 120 Hz), rated ripple current of 790 mA at 120 Hz and 1.13 A at 1 kHz, a leakage current of 770 µA, and a 2000‑hour endurance at 105°C. The part is RoHS compliant and available in tray packing for mass production.

Key Features

• High Voltage & Capacitance — 150 µF rated at 450 V for high‑voltage DC filtering and bulk energy applications.
• Snap‑in Radial Can Package — Snap‑in terminal mounting with compact dimensions φ25 × 30 mm (L: 3 × D: 2.5 cm) to support denser board layouts and easier assembly.
• Temperature & Endurance — Rated for operation from −25°C to +105°C with a 2000‑hour endurance at 105°C under rated voltage and ripple conditions.
• Low Loss (tan δ) — tan δ of 0.20 (max) at 450 V, 120 Hz and 20°C, supporting efficient energy storage with controlled dissipation.
• High Ripple Current Capability — 790 mA at 120 Hz (low frequency) and 1.13 A at 1 kHz (high frequency), enabling effective smoothing under ripple loading.
• Controlled Leakage — Specified leakage current of 770 µA, supporting predictable DC performance after voltage application.
• Regulatory Compliance — RoHS compliant construction for environmental conformity in production assemblies.

Typical Applications

• High‑voltage Power Supplies — Bulk filtering and energy storage where 450 V ratings and 150 µF capacitance meet DC bus or intermediate circuit requirements.
• Power Conversion Modules — DC link or smoothing capacitors in power converters and inverters requiring compact, snap‑in mounted components.
• Industrial Electronics — General‑purpose use in industrial equipment that demands long life at elevated temperatures and reliable ripple performance.

Unique Advantages

• Space‑saving footprint — The LGG series delivers an ultra‑smaller case size (one rank smaller than LGN), helping reduce board area and enable equipment downsizing.
• High‑temperature endurance — 2000 hours at 105°C under rated conditions delivers predictable lifetime performance in thermally demanding installations.
• Measurable ripple handling — Specified ripple currents at both 120 Hz and 1 kHz provide designers with clear margins for thermal and ripple management.
• Stable electrical characteristics — Defined tan δ and leakage specifications allow straightforward thermal and loss budgeting in power designs.
• Manufacturing ready — Tray packing and mass production status simplify procurement and high‑volume assembly planning.
