LGN2W101MELA25

The LGN2W101MELA25 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGN series, rated 100 µF at 450 V. Designed for general‑purpose high‑voltage applications, this polarized capacitor combines a compact φ25 × 25 mm can with elevated endurance and specified ripple handling.

Key value propositions include a 450 V rated voltage, a 3000‑hour endurance at 105°C, and defined low‑ and high‑frequency ripple current limits—making it suitable where durable high‑voltage bulk capacitance and reliable thermal performance are required.

Key Features

• Electrical Capacity — 100 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) for consistent bulk energy storage and decoupling.
• High Voltage Rating — Rated voltage of 450 V for high‑voltage DC applications.
• Loss and Leakage Characteristics — Maximum tan δ of 0.20 (measured at 120 Hz, 20°C) and measured leakage current of 630 µA, supporting predictable damping and insulation behavior.
• Ripple Current Performance — Specified ripple current of 690 mA at 120 Hz and 986.7 mA at 100 kHz for both low‑ and high‑frequency ripple handling.
• Thermal Endurance — Rated for 3000 hours at 105°C under D.C. bias plus rated ripple current, meeting endurance expectations for continuous high‑temperature operation.
• Operating Temperature Range — Specified operating range from −25°C to 105°C for stable performance across typical industrial ambient conditions.
• Package & Mounting — Radial can with snap‑in terminals (φ25 × 25 mm), tray packing; polarized design for secure PCB insertion and mechanical retention.
• Regulatory — RoHS‑compliant.

Typical Applications

• High‑voltage power supplies — Bulk energy storage and smoothing where 450 V rating and 100 µF capacitance meet DC link and filtering needs.
• Industrial power electronics — Provides durable bulk capacitance for converters and inverters that require long endurance at elevated temperatures.
• General-purpose high-voltage circuits — Polarized snap‑in mounting and defined ripple ratings suit a range of general‑purpose high‑voltage designs.

Unique Advantages

• High voltage capability: 450 V rating enables use in higher‑voltage DC systems without stepping up component count.
• Long‑term thermal reliability: 3000 hours endurance at 105°C under rated conditions supports continuous operation in hot environments.
• Measured ripple performance: Explicit ripple current specifications at 120 Hz and 100 kHz allow designers to size capacitors with confidence for both low‑ and high‑frequency ripple.
• Compact snap‑in form factor: φ25 × 25 mm radial can with snap‑in terminals provides secure PCB retention while conserving board area.
• Predictable dielectric behavior: Specified tan δ (0.20 max) and quantified leakage current (630 µA) give clear parameters for loss and insulation planning.
• RoHS compliant: Meets RoHS environmental requirements for regulated markets and supply chains.
