LGN2G561MELB50

The LGN2G561MELB50 is a 560 µF, 400 V snap‑in aluminum electrolytic capacitor from Nichicon’s LGN series. It is a smaller‑sized, radial can snap‑in terminal type designed for general‑purpose power applications that require high voltage handling and extended high‑temperature endurance.

Engineered to withstand sustained rated ripple current at elevated temperature, this part provides designers with a compact, high‑voltage smoothing and energy‑storage option suitable for industrial and power electronics applications where a robust 105°C endurance is required.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance (at 120 Hz, 20°C), suitable for high‑voltage smoothing and DC link duties.
• High‑Temperature Endurance — Specified for operation up to 105°C and rated for 3000 hours endurance at 105°C under DC bias plus rated ripple current (per series specification).
• Ripple Current Capability — Rated ripple current of 1.9 A at 120 Hz and 2.717 A at 100 kHz, enabling effective ripple suppression in power circuits.
• Low‑Temperature Stability for 350–600 V Range — For rated voltages in this range (including 400 V), the impedance ratio Z(–25°C)/Z(+20°C) is specified (max. 8), supporting predictable performance down to –25°C.
• Loss & Leakage Characteristics — Meets series specifications for tan δ (max. 0.15 for rated voltages up to 420 V at 120 Hz, 20°C) and leakage current defined by I ≤ 3/√C (µA) after voltage application at 20°C.
• Package & Mounting — Radial can, snap‑in terminal type for secure board mounting and mechanical stability; one rank smaller case size than LGU in the same series.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple suppression on high‑voltage DC rails in general‑purpose power supplies.
• DC Link / Energy Storage — DC link capacitors and energy buffering in power conversion modules where high voltage and elevated temperature endurance are required.
• Industrial Power Electronics — Use in industrial controllers and converters that need compact high‑voltage capacitors with reliable long‑term performance at up to 105°C.

Unique Advantages

• High‑voltage capability: 400 V rating provides margin for high‑voltage smoothing and DC link applications.
• Extended high‑temperature life: Rated for 3000 hours at 105°C under rated ripple conditions, offering predictable long‑term performance in hot operating environments.
• Compact, snap‑in package: Radial can with snap‑in terminals and a one‑rank smaller case size than LGU saves board area while ensuring secure mounting.
• Measured ripple performance: Specified ripple current values at both 120 Hz and 100 kHz support designers targeting different switching frequencies.
• Defined electrical limits: Series specifications for tan δ and leakage current give clear, verifiable parameters for design verification and margining.
• RoHS compliance: Environmentally compliant construction suitable for regulated markets.
