LGU2G121MELY

The LGU2G121MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in terminal, radial can package. Rated for 400 V and 120 µF with polarization and ±20% tolerance, it is designed for general-purpose electronic applications that require high-voltage capacitance with elevated-temperature endurance.

Key value comes from its 105°C standard rating and the ability to withstand 3,000 hours of rated ripple current at 105°C, providing predictable performance in applications where sustained ripple and elevated operating temperatures are present. The part is RoHS compliant.

Key Features

• Electrical Ratings — 120 µF capacitance at 400 V DC with ±20% tolerance; polarized design suitable for DC energy storage and filtering in high-voltage circuits.
• High-Temperature Endurance — Rated for operation to 105°C and specified to withstand 3,000 hours of applied rated ripple current at 105°C per the LGU series endurance specification.
• Ripple Current Capability — Rated ripple current of 750 mA at 120 Hz and 1.073 A at 100 kHz, with series frequency coefficients provided for higher-frequency derating.
• Mounting & Package — Snap-in terminal, radial can package (L: 4 × D: 2 cm) for secure PCB mounting in assemblies that require durable through-hole retention.
• Reliability Characteristics — Series-level endurance limits: after 3,000 hours at 105°C under rated conditions, capacitance change within ±20%, tan δ ≤ 200% of initial specified value, and leakage current not exceeding initial specification.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-voltage power rails — Provides bulk capacitance and DC smoothing for circuits requiring 400 V operation and reliable performance at elevated temperatures.
• Power filtering and energy storage — Supports sustained ripple environments with rated ripple current values specified at 120 Hz and 100 kHz.
• Industrial and general-purpose electronics — Suitable where a polarized, snap-in aluminum electrolytic solution with 105°C endurance and RoHS compliance is needed.

Unique Advantages

• High-voltage capability: 400 V rating enables use on higher-voltage DC buses without stacking multiple components.
• Elevated-temperature durability: 105°C rating and 3,000-hour ripple endurance provide predictable long-term behavior in hot operating environments.
• Documented ripple performance: Measured ripple current values at 120 Hz and 100 kHz allow designers to size capacitors against known AC stress levels.
• Snap-in package for secure mounting: Radial, snap-in can design simplifies assembly and provides mechanical retention for through-hole assemblies.
• RoHS compliant: Meets current RoHS directive requirements for restricted substances.
