LGN2Z391MELY30

The LGN2Z391MELY30 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power electronics. With a 390 µF capacitance at a 180 V rating and a compact φ20 × 30 mm can, it is focused on bulk energy storage and smoothing in medium‑voltage power circuits.

Engineered for durability in demanding thermal environments, this part provides high ripple handling and long endurance — making it suitable for industrial power supplies, converters, and other equipment requiring stable capacitance and reliable performance up to 105°C.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 180 V rated voltage and a tolerance of −20% to +20%, suited for energy storage and filtering in medium‑voltage circuits.
• High Ripple Handling — Rated ripple current of 1.28 A at 120 Hz and 1.92 A at 100 kHz, supporting steady AC ripple conditions in power converters and supply rails.
• Low Leakage & Controlled Dissipation — Specified leakage current of 790 µA and a tangent of loss angle (tanδ) of 0.15 measured at 20°C, 120 Hz, enabling predictable losses and thermal behavior.
• Endurance & Temperature Range — Designed to meet endurance requirements with 3000 hours at 105°C; operational temperature range from −40°C to +105°C.
• Package & Mounting — Snap‑in radial can (φ20 × 30 mm) for secure panel or board mounting and streamlined assembly; supplied in tray packing for handling and production workflows.
• RoHS Compliance — Compliant to RoHS directive, meeting environmental requirements for electronics manufacturing.

Typical Applications

• Industrial Power Supplies — Bulk filtering and smoothing on intermediate DC rails where 180 V rating and high ripple current capability reduce voltage ripple and improve regulator stability.
• Power Converters & Inverters — Energy storage and ripple absorption in switching stages, leveraging the 1.92 A high‑frequency ripple rating to handle switching harmonics.
• Uninterruptible Power Systems (UPS) — Bulk capacitance for hold‑up and smoothing functions, with endurance specified for prolonged thermal stress at elevated temperatures.
• General Purpose Industrial Equipment — Filtering and decoupling in motor controls, PLCs, and power distribution modules where reliable performance up to 105°C is required.

Unique Advantages

• High Voltage Capability: 180 V rating enables use on medium‑voltage DC rails without overspecifying capacitance.
• Strong Ripple Performance: Dual ripple specifications (1.28 A at 120 Hz and 1.92 A at 100 kHz) give designers predictable thermal and lifetime behavior across frequency ranges.
• Long Endurance at Elevated Temperature: Rated for 3000 hours at 105°C, supporting extended service life in hot enclosures and high‑dissipation environments.
• Compact Snap‑in Form Factor: φ20 × 30 mm can with snap‑in terminals provides a space‑efficient solution for high‑capacitance needs in constrained layouts.
• Controlled Electrical Losses: Specified tanδ of 0.15 (20°C, 120 Hz) and defined leakage current support predictable efficiency and thermal design.
• RoHS Compliant Packaging: Tray packing and RoHS compliance simplify manufacturing integration and environmental compliance.
