LGW2W820MELZ25

The LGW2W820MELZ25 is a Nichicon aluminum electrolytic capacitor in a snap-in terminal can, rated for 450 V and 82 µF with ±20% tolerance. It is designed for general-purpose power applications that require high ripple current handling and extended endurance at elevated temperatures.

Key value propositions include high ripple-current capability, long 3000-hour endurance at 105°C under rated ripple conditions, and RoHS compliance—delivered in a compact φ22 × 25 mm radial snap-in package for reliable board-level installation.

Key Features

• Electrical Rating — 82 µF capacitance at a 450 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current — Low-frequency ripple current of 960 mA at 120 Hz and high-frequency capability up to approximately 1.373 A (50 kHz), suitable for demanding AC ripple and smoothing tasks.
• Loss Tangent (tan δ) — tan δ ≤ 0.20 at 20°C and 120 Hz for the 450 V rating, supporting predictable dissipation characteristics.
• Low Leakage — Specified leakage current of 570 µA (measured after 5 minutes at 20°C), consistent with electrolytic capacitor performance expectations.
• Endurance & Reliability — Qualified for 3000 hours of operation at 105°C with DC bias plus rated ripple current; capacitance, tan δ, and leakage remain within specified limits after endurance testing.
• Package & Mounting — Snap-in terminal radial can, size φ22 × 25 mm (L × D), supplied in tray packing and available as a mass-production item for volume manufacturing.
• Operating Range — Rated for operation from −25°C to +105°C for the 400–450 V range, matching applications requiring elevated-temperature stability.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Use where high-voltage smoothing and ripple suppression are required at up to 450 V working voltage.
• DC Link / Energy Storage — Suitable for DC link and bulk energy-storage roles that benefit from 82 µF capacitance combined with high ripple capability.
• Industrial Power Electronics — Appropriate for general-purpose industrial applications that demand long endurance at elevated temperatures and robust ripple handling.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 960 mA (120 Hz) and ~1.373 A (50 kHz) reduce the need for parallel parts or additional filtering components.
• Extended high-temperature endurance: 3000 hours at 105°C under rated ripple conditions provides predictable long-term performance in hot operating environments.
• Compact snap-in package: φ22 × 25 mm radial snap-in can enables secure board mounting and efficient use of panel space in mass-production assemblies.
• Clear electrical specifications: 450 V rating, tan δ ≤ 0.20 (120 Hz, 20°C), and specified leakage current make it straightforward to model thermal and electrical behavior in designs.
• RoHS compliance: Meets environmental regulatory requirements for restricted substances.
