LGU2G331MELA

The LGU2G331MELA is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in terminal, radial can package. It provides 330 µF capacitance at a 400 V rating with polarized construction and is intended for general-purpose use.

Designed for elevated-temperature operation, this LGU part withstands 3000 hours of rated ripple current at 105°C and is RoHS compliant, offering a high-voltage bulk capacitance option for designs that require extended endurance and robust ripple handling.

Key Features

• Capacitance & Voltage — 330 µF capacitance with a 400 V rated voltage and ±20% tolerance, delivering high-voltage bulk capacitance in a single polarized unit.
• High‑temperature Endurance — Specified endurance of 3000 hours at 105°C under rated ripple conditions, providing predictable performance in elevated-temperature environments.
• Ripple Current Capability — Rated ripple current of 1.44 A at 120 Hz (low frequency) and 2.059 A at 50 kHz (high frequency), enabling reliable ripple handling across common operating frequencies.
• Operating Range — Polarized capacitor with an operating temperature range specified from −25°C to 105°C for the 315–450 V range in the LGU series.
• Package & Mounting — Radial can, snap-in terminal type for secure PCB mounting; physical size listed as L: 5 × D: 2.5 cm for layout planning.
• Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose high-voltage circuits — Suited to circuits that require a polarized 330 µF, 400 V aluminum electrolytic capacitor for bulk capacitance in general-purpose applications.
• Elevated-temperature service — Applicable where sustained operation and ripple endurance at temperatures up to 105°C are required, supported by the LGU series 3000-hour specification.
• PCB snap-in installations — Used in assemblies that accept radial, snap-in can capacitors and benefit from a secure mechanical mount and compact L × D footprint.

Unique Advantages

• Long-term high-temperature endurance: Rated to withstand 3000 hours of applied rated ripple current at 105°C, helping maintain capacitance and leakage characteristics over time under stress.
• High-voltage capability: 400 V rating provides higher DC working voltage for designs that need substantial voltage margin in a single capacitor.
• Measurable ripple performance: Specified ripple current values at 120 Hz and 50 kHz allow designers to match the component to expected operating frequencies and thermal loading.
• Compact snap-in form factor: Radial, can-style snap-in package with defined dimensions simplifies PCB placement and mechanical retention for through-hole assemblies.
• Regulatory compliance: RoHS conformity supports use in designs requiring restricted-substance compliance.
