LGY1H103MELB50

The LGY1H103MELB50 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGY series designed for long‑life, high‑reliability power applications. It delivers 10 mF capacitance at a 50 V rating in a radial snap‑in can package and is polarized for DC smoothing and energy‑storage tasks.

Engineered for demanding industrial environments, this part is specified to withstand 5000 hours of rated ripple current at 105°C and is suited for industrial power supplies and ballast applications where dependable performance and extended endurance are required. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 10 mF nominal capacitance with a 50 V rated voltage; capacitance tolerance is ±20% (–20% to +20%) at 120 Hz, 20°C.
• Long‑Life Endurance — Specified to meet endurance requirements after 5000 hours of DC bias plus rated ripple current at 105°C, with limits for capacitance change, tan δ and leakage current defined by the LGY series specification.
• Ripple Current Capability — Rated ripple current of 3.1 A at 120 Hz and 3.565 A at 50 kHz, enabling handling of sustained AC ripple in power circuits.
• Temperature Range — Operating from –40°C to +105°C for reliable performance across wide ambient conditions.
• Mounting & Package — Radial, can‑type snap‑in terminal for robust board mounting in power assemblies; size approximately L: 5 × D: 3 cm.
• Leakage and Dissipation Characteristics — Leakage current meets the series limit I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) limits apply per rated voltage in the LGY series specification.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing where sustained ripple handling and long life at elevated temperature are required.
• Ballast Circuits — Designed for ballast application environments that demand stable capacitance and endurance under continuous ripple current.
• General Purpose Power Electronics — DC link, reservoir, and decoupling uses in equipment requiring polarized electrolytic capacitance in a snap‑in package.
