LGG2G391MELB35

The LGG2G391MELB35 is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package from Nichicon's LGG series. It delivers 390 µF at 400 V in an ultra‑smaller‑sized snap‑in format suited for compact equipment designs.

Designed for general‑purpose applications, this capacitor combines high voltage rating, a compact φ30 × 35 mm case size, and a 105 °C endurance rating to support robust operation in space‑constrained power modules and assemblies.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance at 400 V for high‑voltage bulk capacitance requirements.
• Compact Snap‑in Package — Radial, can snap‑in mounting in a φ30 × 35 mm (L: 3.5 × D: 3.0 cm) footprint; LGG series is one rank smaller than LGN for equipment downsizing.
• Temperature Range & Endurance — Operating temperature −25 °C to +105 °C with an endurance rating of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple Current Ratings — Rated ripple current of 1.4 A at 120 Hz and 2.002 A at 100 kHz (specified values as tested).
• Electrical Stability — Capacitance tolerance −20% to +20%; leakage current specified by I ≤ 3√CV (μA) after 5 minutes at 20 °C; tan δ (max.) 0.15 at 120 Hz, 20 °C for voltages up to 420 V.
• Low‑temperature Performance — Impedance stability characterized with Z(−25 °C)/Z(+20 °C) up to 8 for 400–450 V ratings, enabling defined behavior in colder environments.
• RoHS Compliant — Manufactured to meet RoHS directive requirements.

Typical Applications

• General‑purpose power modules — Provides high‑voltage bulk capacitance for assemblies that require 390 µF at 400 V in a compact snap‑in form.
• Compact equipment designs — Suited for equipment downsizing due to the LGG series’ reduced case size (one rank smaller than LGN).
• High‑temperature operating environments — Useful where sustained operation at up to 105 °C with specified endurance is required.

Unique Advantages

• High voltage with substantial capacitance: 390 µF at 400 V delivers significant energy storage capacity for high‑voltage applications in a single component.
• Space‑saving snap‑in package: φ30 × 35 mm radial can and snap‑in terminals reduce board footprint while providing secure mechanical mounting.
• Defined ripple handling: Specified ripple currents of 1.4 A (120 Hz) and 2.002 A (100 kHz) allow designers to match component selection to expected ripple stress.
• High‑temperature endurance: Rated for 2000 hours at 105 °C with established post‑test limits on capacitance, tan δ, and leakage current to support reliability planning.
• Predictable electrical limits: Leakage current limit defined by I ≤ 3√CV (μA) and tan δ ≤ 0.15 (at 120 Hz, 20 °C) for the applicable voltage range simplify design verification.
• RoHS compliance: Conforms to RoHS directive requirements for environmentally restricted substance planning.
