LGN2Z391MELZ25

The LGN2Z391MELZ25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGN series. It provides 390 µF capacitance at a rated voltage of 180 V in a compact φ22 × 25 mm can and is offered in tray packing for production handling.

Designed for general‑purpose applications, this polarized capacitor combines high ripple current capability with extended endurance at elevated temperature: rated for operation from −40°C to +105°C and endurance of 3000 hours at 105°C under rated ripple conditions.

Key Features

• Capacitance & Tolerance — 390 µF nominal with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 180 V DC rating for higher voltage general‑purpose circuits.
• High Temperature Endurance — Qualified for 3000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Ripple Current Handling — Low‑frequency ripple current 1.28 A (120 Hz) and high‑frequency ripple current 1.92 A (100 kHz), supporting applications with significant AC ripple stress.
• Loss Characteristic — tan δ (DF) max 0.15 at 20°C, 120 Hz, useful for assessing dissipation under AC conditions.
• Leakage Current — Specified leakage current of 790 µA (after standard voltage application), enabling predictable standby characteristics.
• Temperature Range — Operates from −40°C to +105°C, suitable for a wide thermal envelope.
• Package & Mounting — Snap‑in radial can, compact φ22 × 25 mm size, tray packed for manufacturing efficiency.
• Compliance — RoHS compliant.

Typical Applications

• General‑purpose power circuits — Use where a polarized 390 µF, 180 V snap‑in aluminum electrolytic capacitor is required and where endurance at 105°C and defined ripple handling are important.
• High‑ripple environments — Suitable for circuits subject to continuous ripple currents up to the specified 1.28 A (120 Hz) and 1.92 A (100 kHz) ratings.
• Compact assemblies — The φ22 × 25 mm can size provides a smaller case option while delivering rated capacitance and voltage for space‑constrained designs.

Unique Advantages

• Extended high‑temperature life: 3000‑hour endurance at 105°C under rated ripple conditions ensures long‑term stability in elevated temperature applications.
• Strong ripple performance: Specified low‑ and high‑frequency ripple current ratings (1.28 A at 120 Hz; 1.92 A at 100 kHz) enable reliable operation in AC‑stressed circuits.
• Compact snap‑in form factor: φ22 × 25 mm can with snap‑in terminals balances size and serviceability for production boards and assemblies.
• Predictable electrical characteristics: Low tan δ (0.15 max at 20°C, 120 Hz) and defined leakage current (790 µA) support predictable thermal and standby behavior.
• Production ready: Tray packing and mass‑production status support volume assembly and procurement planning.
• RoHS compliant: Meets RoHS requirements for use in compliant product builds.
