LGN2D391MELZ25

The LGN2D391MELZ25 is a 390 µF, 200 V polarized aluminum electrolytic capacitor in Nichicon’s LGN snap-in series. It delivers bulk capacitance in a compact snap-in can (φ22 × 25 mm) intended for general-purpose applications that require robust ripple handling and extended high-temperature endurance.

Designed for board-level snap-in mounting and tray packing, this part offers a combination of rated capacitance, high-frequency ripple capability, and a guaranteed 3,000-hour endurance at 105°C—making it suitable where long service life and stable performance under DC bias and ripple are required.

Key Features

• Electrolytic Core 390 µF capacitance with polarized construction for bulk energy storage and smoothing in DC circuits.
• Rated Voltage 200 V DC rating to support higher-voltage general-purpose designs.
• Snap‑In Mounting & Package Snap-in terminal type in a radial can (φ22 × 25 mm) for secure board-level installation; supplied in tray packing.
• High-Temperature Endurance Qualified for 3000 hours of operation at 105°C with rated ripple current applied, per LGN series endurance specifications.
• Ripple Current Performance Low-frequency ripple: 1.31 A at 120 Hz; high-frequency ripple: 1.965 A at 100 kHz, supporting both power-line and switching ripple environments.
• Electrical Losses & Leakage Tangent of loss angle (tanδ) 0.15 (measured at 20°C, 120 Hz) and leakage current of 830 µA, enabling predictable dissipation and standby behavior.
• Operating Range Temperature range from –40°C to +105°C to cover a wide set of general-purpose thermal environments.
• Manufacturing Status & Compliance Mass production availability and RoHS-compliant construction.

Typical Applications

• General-purpose power circuits — Use where 390 µF at 200 V bulk capacitance is required and snap-in mounting is preferred for board-level retention.
• High-temperature environments — Suitable for designs needing sustained performance at up to 105°C with 3000-hour rated endurance.
• Ripple-intensive designs — Applications that require defined low- and high-frequency ripple handling thanks to rated ripple currents at 120 Hz and 100 kHz.

Unique Advantages

• Long high‑temperature life: 3000 hours at 105°C under rated ripple current provides predictable endurance for long-term deployments.
• High voltage rating: 200 V DC rating enables use in higher-voltage general-purpose circuits.
• Dual-frequency ripple capability: Specified ripple ratings at 120 Hz and 100 kHz support both mains and switching power filtering needs.
• Compact snap‑in form factor: φ22 × 25 mm can with snap-in terminals balances board space and mechanical retention for through-hole assemblies.
• Controlled electrical characteristics: tanδ = 0.15 and leakage current = 830 µA provide measurable dissipation and leakage behavior for design calculations.
• RoHS compliant and production-ready: Mass production status and RoHS compliance simplify procurement and regulatory considerations.
