LGU1H392MELA

The LGU1H392MELA is a snap‑in aluminum electrolytic capacitor from Nichicon's LGU series, offering 3.9 mF capacitance at a 50 V rating. It is a snap‑in terminal, radial can package designed for general‑purpose electronic applications that require reliable bulk capacitance and sustained ripple current handling.

Engineered for elevated operating temperatures, this part delivers guaranteed performance after prolonged exposure to rated ripple current at 105°C, making it suitable for designs that demand stable capacitance and endurance in thermally challenging environments.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 50 V rated voltage to support bulk energy storage and filtering tasks.
• Endurance & Temperature Range — Rated for operation from −40°C to +105°C and specified to withstand 3000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Low‑frequency ripple current 2.28 A at 120 Hz and high‑frequency ripple current 2.622 A at 50 kHz, supporting sustained AC stress in power circuits.
• Leakage & Dissipation — Leakage current specified at 1320 µA and tan δ (DF) of 0.3 measured at 20°C, 120 Hz for predictable loss characteristics.
• Package & Mounting — Radial, can snap‑in package (φ25 × 30L) for secure board retention and straightforward assembly; supplied in tray packing for production handling.
• Tolerance & Polarization — Capacitance tolerance ±20% and polarized construction typical of aluminum electrolytic designs for polarized DC applications.
• Environmental Compliance — RoHS compliant, aligning with restricted substances requirements noted in the product documentation.

Typical Applications

• General Purpose Power Filtering — Provides bulk capacitance and ripple current handling for smoothing and decoupling in power supply stages.
• Industrial Power Electronics — Suited for equipment that requires sustained high‑temperature endurance and continuous ripple handling at elevated ambient conditions.
• Commercial Electronics — Used where compact bulk energy storage is needed with reliable long‑term performance across −40°C to +105°C.

Unique Advantages

• Proven high‑temperature endurance: Specified endurance of 3000 hours at 105°C under rated ripple current helps ensure long service life in hot environments.
• Robust ripple handling: Distinct low‑ and high‑frequency ripple current ratings (2.28 A at 120 Hz; 2.622 A at 50 kHz) allow designers to size the component precisely for expected operating spectra.
• Compact snap‑in package: φ25 × 30L radial can with snap‑in terminals delivers secure board mounting and simplified assembly for production environments.
• Predictable electrical behavior: Specified tan δ and leakage current measurements at 20°C, 120 Hz provide verifiable loss and leakage parameters for design validation.
• Regulatory alignment: RoHS compliance supports use in designs requiring restricted‑substance conformity.
