LGN2G121MELZ30

The LGN2G121MELZ30 is a 120 µF, 400 V polarized aluminum electrolytic capacitor in a snap-in terminal radial can. It is designed for general-purpose electronic circuits requiring high-temperature endurance and reliable ripple-current handling.

As a snap-in terminal type from the LGN series, this part delivers a compact case size (one rank smaller than LGU) and is rated for continuous operation up to 105°C with a specified 3000-hour endurance under rated ripple current at 105°C.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, providing stable bulk capacitance for high-voltage applications.
• High-temperature endurance — Rated for operation from −25°C to +105°C with an endurance specification of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current.
• Snap-in radial can package — Snap-in terminal mounting for secure mechanical retention in assemblies; package case is radial, can - snap-in.
• Ripple current capability — Rated ripple current of 730 mA at 120 Hz and 1.044 A at 100 kHz, enabling effective smoothing and decoupling under AC ripple conditions.
• Leakage and loss characteristics — Meets standard leakage current limits and tan δ performance as specified by the LGN series; designed for controlled leakage after five minutes at rated voltage.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulatory-driven designs.
• Compact dimensions — Smaller case size compared with LGU series options, with part dimensions approximately L: 3 cm × D: 2.2 cm for space-constrained layouts.

Typical Applications

• General-purpose electronic circuits — Provides bulk capacitance and energy buffering for a wide range of general-purpose assemblies that require a 400 V polarized aluminum electrolytic capacitor.
• High-temperature assemblies — Suited for designs that must sustain operation at elevated temperatures up to 105°C with a defined 3000-hour ripple endurance.
• High-voltage modules — Useful where a compact 120 µF, 400 V snap-in capacitor with defined ripple-current ratings is required for smoothing and decoupling.

Unique Advantages

• Long high-temperature life: 3000 hours endurance at 105°C under rated conditions, supporting reliability in extended high-temperature operation.
• High-voltage capability: 400 V rated voltage provides margin for high-voltage circuits while maintaining a compact footprint.
• Robust ripple handling: Specified ripple current values at both 120 Hz and 100 kHz enable predictable performance across low and high ripple frequencies.
• Space-saving case: One rank smaller case size than LGU-series equivalents, helping reduce board space without sacrificing rated performance.
• Secure mounting: Snap-in terminal radial can offers reliable mechanical retention for high-vibration or vertical-mount assemblies.
• Regulatory readiness: RoHS compliance supports designs targeting restricted-substance requirements.
