LGW2G391MELC35

The LGW2G391MELC35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGW series. It delivers 390 µF capacitance at a 400 V rated voltage in a radial, can‑style snap‑in package.

Designed for general‑purpose power circuitry, this capacitor provides high ripple current capability and prolonged endurance—specified to withstand 3000 hours of rated ripple current at 105°C—while meeting RoHS (2011/65/EU, (EU)2015/863) requirements.

Key Features

• Electrical Performance – 390 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage suitable for higher‑voltage DC bus applications.
• High Ripple Current – Rated ripple current of 2.52 A at 120 Hz and 3.604 A at 50 kHz for robust AC ripple handling in power circuits.
• Endurance – Rated to withstand 3000 hours of rated ripple current at 105°C; meets the LGW series endurance criteria for capacitance, tan δ and leakage current after test.
• Temperature Range – Operating temperature range of −25°C to +105°C, suited to elevated operating environments defined for the 400 V product group.
• Package & Mounting – Radial, can‑style snap‑in terminal package (L: 3.5 × D: 3.5 cm) for secure PCB mounting in power modules and assemblies.
• Compliance – RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power electronics – Bulk energy storage and smoothing on 400 V DC buses where high ripple current capability is required.
• Power supply filtering – Input/output smoothing and ripple attenuation in power supplies, leveraging the specified ripple current at 120 Hz and higher frequencies.
• Industrial power modules – Use in industrial power assemblies that require long endurance at elevated temperatures (3000 h at 105°C).

Unique Advantages

• Proven ripple endurance: Withstands 3000 hours of rated ripple current at 105°C, supporting long‑term reliability under continuous ripple stress.
• High‑voltage capability: 400 V rated voltage enables use on higher‑voltage DC rails without changing capacitor families.
• Strong HF ripple performance: Higher frequency ripple handling is supported—specification lists 3.604 A at 50 kHz and series frequency coefficients that increase HF ripple allowance for the 400–450 V group.
• Secure snap‑in mounting: Radial snap‑in can simplifies board installation and mechanical retention in power assemblies.
• RoHS compliance: Meets RoHS directives (2011/65/EU, (EU)2015/863) for regulatory compliance in manufacturing.
• Compact footprint: 3.5 × 3.5 cm can size balances capacitance and board area for power designs requiring moderate energy storage.
