LGNW6820MELY25

The LGNW6820MELY25 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LGN series designed for general-purpose high-voltage applications. It delivers 82 µF at a 420 V rating in a compact, smaller-sized “snailer” case and is built for elevated-temperature operation up to 105°C.

Engineered for long endurance under ripple load, this part is specified to withstand 3000 hours of rated ripple current at 105°C and is RoHS compliant for regulatory compatibility.

Key Features

• High-voltage, mid-value capacitance — 82 µF rated at 420 V for energy storage and smoothing in high-voltage circuits.
• 105°C endurance — Rated for operation to 105°C with a guaranteed endurance of 3000 hours under D.C. bias plus rated ripple current at 105°C.
• Compact snap-in package — Radial, can-style snap-in mounting with dimensions L: 2.5 × D: 2.0 cm for reduced board footprint; one rank smaller case size than LGU series.
• Ripple current capability — Specified ripple current of 640 mA at 120 Hz and 915.2 mA at 100 kHz for handling AC components on DC rails.
• Standard tolerances and polarization — Capacitance tolerance ±20% (–20% to +20%) and polarized construction for correct orientation in circuits.
• Series electrical characteristics — Series specifications include tan δ max 0.15 for 160–420 V parts (measured at 120 Hz, 20°C) and leakage current defined as I ≤ 3√C µA after 5 minutes at 20°C.
• Environmental compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Smoothing and ripple reduction on high-voltage DC rails where 420 V rating and elevated ripple capability are required.
• Industrial power electronics — Bulk capacitance for converters and power supplies that operate up to 105°C and benefit from a compact snap-in can.
• Space-constrained designs — Replacement or new designs that need a smaller case size than LGU while retaining endurance and voltage capability.

Unique Advantages

• High-temperature reliability: 3000-hour endurance at 105°C under rated ripple current, supporting sustained operation in hot environments.
• Robust ripple handling: Explicit ripple current ratings at both 120 Hz and 100 kHz enable designers to size capacitors for real-world AC components on DC lines.
• Compact form factor: One rank smaller case size than LGU gives more layout flexibility without sacrificing voltage rating.
• Snap-in mounting: Radial snap-in terminals provide secure mechanical attachment for through-hole assemblies and ease of installation.
• Clear electrical limits: Defined leakage current and tan δ limits (series values) make it straightforward to verify electrical performance during design and qualification.
• Regulatory compliance: RoHS conformity supports integration into assemblies targeting restricted-substance regulations.

Why Choose LGNW6820MELY25?

The LGNW6820MELY25 balances a high 420 V rating and 82 µF capacitance with a reduced footprint and snap-in reliability, making it suitable for general-purpose high-voltage circuits that must tolerate elevated temperatures and sustained ripple. Its specified endurance (3000 hours at 105°C) and documented ripple performance give designers quantifiable parameters for thermal and lifetime budgeting.

This part is a practical choice for engineers and procurement teams seeking a compact, RoHS-compliant aluminum electrolytic solution from Nichicon’s LGN series for industrial and general-purpose power designs where voltage rating, ripple handling, and elevated-temperature endurance matter.
