LGU1J392MELA

The LGU1J392MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, rated 63 V with 3900 µF (3.9 mF) capacitance and ±20% tolerance. It is designed for general‑purpose applications that require high ripple handling and extended endurance up to 105°C.

Key value propositions include robust ripple current capability across low and high frequencies, a long 3000‑hour endurance at 105°C under rated ripple conditions, and a compact φ25×40 mm snap‑in can for secure mounting and production handling.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance at a rated voltage of 63 V with ±20% tolerance (120 Hz, 20°C).
• Mounting & Package — Snap‑in terminal type in a radial, can snap‑in package with dimensions φ25 × 40 mm for secure board retention and easy assembly.
• Ripple Current Performance — Low‑frequency ripple current: 2.54 A at 120 Hz; high‑frequency ripple current: 2.921 A at 50 kHz, enabling sustained AC stress handling across typical power frequencies.
• Loss Factor (tan δ) — Specified tan δ maximum of 0.25 at 20°C and 120 Hz for 63 V ratings, supporting predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 1480 µA (I ≤ 3 CV(µA) after 5 minutes at 20°C), allowing designers to budget for leakage in DC circuits.
• High‑Temperature Endurance — Meets endurance requirements for 3000 hours at 105°C with rated ripple current applied, per LGU series specifications.
• Operating Temperature Range — −40°C to 105°C, covering a wide range of environmental conditions for general‑purpose electronics.
• Compliance & Production — RoHS‑compliant and available in tray packing; part is in mass production for volume deployment.

Typical Applications

• General‑purpose circuits — Suited for designs that require a 63 V, 3.9 mF electrolytic capacitor in a snap‑in package for board retention and bulk energy storage.
• Power handling modules — Used where defined low‑ and high‑frequency ripple current capability and stable dissipation (tan δ) are needed.
• High‑temperature environments — Applicable in equipment operating up to 105°C thanks to 3000‑hour endurance under rated ripple conditions.

Unique Advantages

• High ripple tolerance: Specified ripple current values at 120 Hz and 50 kHz help ensure reliable performance under AC stress.
• Long endurance at 105°C: Rated for 3000 hours with rated ripple current applied, providing predictable lifetime behavior in elevated temperatures.
• Reliable electrical characteristics: Defined tan δ (0.25 at 63 V, 20°C/120 Hz) and controlled leakage current enable accurate thermal and leakage budgeting.
• Secure snap‑in mounting: Radial snap‑in can (φ25×40 mm) simplifies mechanical retention for production assemblies.
• RoHS compliant and production ready: Tray packed and in mass production for consistent supply and handling in volume manufacturing.
