LGN2G121MELY35

The LGN2G121MELY35 is a Nichicon LGN series aluminum electrolytic capacitor in a snap‑in radial can package designed for general purpose electronic applications. It combines a 120 µF capacitance with a 400 V rated voltage, a polarized snap‑in termination and a reduced case size relative to the LGU series.

Designed to operate up to 105°C, this capacitor delivers specified endurance under continuous ripple conditions and is RoHS compliant, making it suitable for equipment requiring compact, high‑voltage bulk capacitance with proven thermal endurance.

Key Features

• Capacitance and Voltage — 120 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance for predictable bulk energy storage and filtering.
• High‑Temperature Endurance — Rated for operation up to 105°C with a specified lifetime of 3000 hours at 105°C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Performance — Handles 730 mA at 120 Hz (low frequency) and 1.044 A at 100 kHz (high frequency), enabling stable operation under continuous ripple conditions.
• Compact Snap‑In Package — Snap‑in radial can package with a smaller case size than LGU series variants, facilitating denser board layouts and robust mechanical mounting.
• Operating Range and Polarization — Polarized capacitor specified for −25°C to +105°C operation and designed for polarized circuit use.
• Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — For use in general purpose electronic equipment that requires a 400 V, 120 µF polarized snap‑in electrolytic capacitor.
• Power Supply Filtering — Provides bulk capacitance and ripple handling where a compact high‑voltage capacitor is required.
• Industrial Power Circuits — Suitable for industrial equipment requiring high‑temperature endurance and continuous ripple capability at elevated temperatures.

Unique Advantages

• Long Thermal Endurance: Withstands 3000 hours of rated ripple current at 105°C, supporting reliability in high‑temperature operating environments.
• High Voltage Capability: 400 V rating provides headroom for high‑voltage applications while maintaining compact size.
• Compact, Secure Mounting: Snap‑in radial can construction enables firm PCB mounting and a smaller case footprint compared with the LGU series.
• Wide Ripple Frequency Range: Specified ripple current performance at both 120 Hz and 100 kHz supports diverse power‑conversion topologies.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted‑substance requirements.
