LGN2D122MELA50

The LGN2D122MELA50 is a Nichicon LGN‑series snap‑in aluminum electrolytic capacitor delivering 1200 µF at a 200 V rating in a compact φ25 × 50 mm can. It is a general‑purpose, snap‑in terminal design intended for applications that require bulk capacitance and sustained ripple performance at elevated temperatures.

Designed for durability under stress, this part withstands 3000 hours of rated ripple current at 105°C and is manufactured to RoHS compliant standards, making it suitable for production deployments where long‑term reliability and predictable end‑of‑life behavior are required.

Key Features

• Capacitance & Voltage — 1200 µF rated capacitance with a 200 V working voltage and tolerance of −20% to +20%.
• Snap‑in Can Construction — Radial can with snap‑in terminals for secure through‑hole mounting and robust mechanical retention.
• High‑Temperature Endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current; meets the LGN series endurance criteria for long service life.
• Ripple Performance — Low‑frequency ripple current 2.65 A (120 Hz) and high‑frequency ripple current 3.975 A (100 kHz), enabling effective smoothing across a range of switching frequencies.
• Loss and Leakage — Tangent of loss angle (tan δ) max 0.15 (measured at 20°C, 120 Hz) and specified leakage current of 1460 µA.
• Operating Temperature Range — −40°C to +105°C, consistent with LGN series ratings for 160–250 V parts.
• Compact Size & Tray Packaging — Physical dimension φ25 × 50 mm and supplied in tray packing for production handling.
• RoHS Compliant — Conforms to applicable RoHS directive requirements.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing where 1200 µF at 200 V and sustained ripple capability at elevated temperature are required.
• Industrial power electronics — Suitable for power assemblies that need sustained ripple handling (2.65 A at 120 Hz; 3.975 A at 100 kHz) and long endurance at 105°C.
• Production assemblies requiring robust mounting — Snap‑in terminal can design supports reliable through‑hole installation and mechanical retention in assembled boards.

Unique Advantages

• Long endurance under rated ripple — Withstands 3000 hours application of rated ripple current at 105°C, providing predictable ageing and replacement planning.
• Wide operating temperature span — −40°C to +105°C rating supports a range of environmental conditions without derating outside the specified range.
• High ripple handling at multiple frequencies — Specified ripple currents at both 120 Hz and 100 kHz accommodate legacy and modern switching‑frequency environments.
• Clear electrical limits for design confidence — Defined tan δ (0.15 at 20°C, 120 Hz) and measured leakage current (1460 µA) enable accurate thermal and leakage budgeting in designs.
• Production‑ready packaging — Tray packing facilitates automated handling and assembly in production lines.
• RoHS compliance — Meets environmental directives for lead‑free production environments.
