LGN2V561MELC35

The LGN2V561MELC35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGN series, designed for general-purpose power applications. It provides 560 µF capacitance at a 350 V rating and is built for high-temperature endurance with qualification for 3000 hours of rated ripple current at 105°C.

Packaged in a radial can with snap-in mounting, this polarized capacitor is RoHS compliant and offers compact sizing relative to comparable LGU-series parts.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a 350 V rated working voltage; capacitance tolerance ±20% (120 Hz, 20°C).
• High-temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C; endurance criteria include capacitance within ±20% and leakage current not exceeding initial specified value after test.
• Temperature Range — Operating temperature range for the 350 V rating is −25°C to +105°C.
• Ripple Current Capability — Rated ripple current of 1.5 A at 120 Hz and 2.145 A at 100 kHz, enabling robust AC filtering under bias.
• Low Leakage Current — Leakage current specified as I ≤ 3/√C (µA) after 5 minutes’ application of rated voltage at 20°C (C = rated capacitance in µF).
• Electrical Loss — Tangent of loss angle (tan δ) max 0.15 measured at 120 Hz, 20°C for rated voltages in the 160–420 V range (applies to 350 V parts).
• Package & Mounting — Radial can with snap-in terminals for PCB retention and mechanical stability; compact case size (one rank smaller than LGU series).
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power supplies — Bulk smoothing and decoupling in high-voltage power rails where 350 V rating and 560 µF capacitance are required.
• Industrial power modules — Filtering and energy buffering in industrial equipment that operates within −25°C to +105°C and requires long-term ripple endurance.
• High-voltage DC systems — Voltage-holding and ripple management in DC link or intermediate circuits benefiting from specified ripple current capabilities at 120 Hz and 100 kHz.

Unique Advantages

• Proven high-temperature durability — Rated for 3000 hours at 105°C under rated ripple, providing predictable life performance in elevated-temperature environments.
• High voltage capability — 350 V rating supports higher-voltage designs without series stacking, simplifying design and BOM.
• Measured AC performance — Specified ripple current values at both low and high frequencies allow designers to size capacitors against real operating conditions.
• Compact snap-in package — Radial, snap-in can offers strong PCB retention and a smaller case footprint relative to the LGU family, aiding denser board layouts.
• Quantifiable electrical parameters — Clear limits for leakage current (I ≤ 3/√C) and tan δ (max 0.15 at 120 Hz) facilitate thermal and loss budgeting in designs.
• Regulatory compliance — RoHS compliance supports use in assemblies targeting restricted-substance regulations.
