LGN2W820MELY30

The LGN2W820MELY30 from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LGN series designed for general‑purpose high‑voltage applications. It combines a 450 V rated voltage with 82 µF capacitance in a smaller‑sized snap‑in can intended for compact power designs.

Engineered for elevated temperature endurance, this part withstands 3,000 hours of rated ripple current at 105°C and is RoHS compliant, making it suitable for robust industrial and power electronics uses that require long‑term ripple handling and compact packaging.

Key Features

• Rated Performance — 82 µF capacitance at 450 V provides high‑voltage energy storage for DC bus and filtering applications.
• High Temperature Endurance — Specified to endure 3,000 hours of rated ripple current at 105°C, with post‑test limits: capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value.
• Ripple Current Capability — Rated ripple current of 640 mA at 120 Hz and 915.2 mA at 100 kHz to support continuous AC ripple conditions under rated bias.
• Compact Snap‑In Package — Radial, snap‑in can with dimensions L: 3 cm × D: 2 cm and a maximum seated height of 1.181 inch, offering a smaller case size than the LGU series for tighter layouts.
• Wide Operating Range — Operating temperature range of −25°C to +105°C (per part rating for 350–600V range), with low‑temperature impedance characteristics specified for reliable performance at −25°C.
• Electrical Characteristics — Capacitance tolerance ±20% (at 120 Hz, 20°C), leakage current defined by I ≤ 3/√C (µA) after 5 minutes at 20°C, and tan δ maximum 0.20 for 450–600 V at 120 Hz, 20°C.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Provides bulk storage and smoothing in high‑voltage supply rails where 450 V rating and high ripple endurance are required.
• DC bus filtering — Supports DC link and bus capacitor roles in power conversion systems that demand sustained ripple performance at elevated temperatures.
• Power conversion equipment — Suitable for inverters, converters and other general‑purpose power electronics requiring a compact, high‑voltage electrolytic solution.

Unique Advantages

• Long high‑temperature life: 3,000‑hour ripple endurance at 105°C reduces replacement frequency and supports continuous operation in hot environments.
• High‑voltage capability: 450 V rating enables use in higher‑voltage power rails without series stacking.
• Compact footprint: One rank smaller case size than LGU and small L×D footprint (3 × 2 cm) help save board area in dense assemblies.
• Robust ripple handling: Clear ripple current specifications at 120 Hz and 100 kHz (640 mA and 915.2 mA) allow designers to match capacitor selection to expected operating frequencies.
• Defined electrical limits: Specified tan δ, leakage current formula, and low‑temperature impedance ratios enable predictable behavior and easier validation in designs.
• RoHS compliant: Meets regulatory requirements for restricted substances in electronic equipment.
