LGN2E331MELZ30

The LGN2E331MELZ30 is a Nichicon aluminum electrolytic capacitor in a snap-in (radial can) format designed for general-purpose power applications. It delivers 330 µF capacitance at a 250 V rating with polarized construction and a compact package footprint (approximately 3.0 × 2.2 cm).

Engineered for elevated-temperature reliability, this part is specified for operation from −40 °C to 105 °C and is rated to withstand 3000 hours of application of rated ripple current at 105 °C. It is RoHS compliant for environmental consistency.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance for general-purpose DC smoothing and energy storage needs.
• Snap-in Radial Can Package — Snap-in terminal type and radial can construction for secure PCB mounting and robust mechanical retention.
• High-Temperature Endurance — Specified endurance of 3000 hours at 105 °C with rated ripple current applied, supporting extended life in elevated-temperature environments.
• Ripple Current Ratings — Rated ripple current of 1.2 A at 120 Hz and 1.8 A at 100 kHz, giving defined performance across low and high frequency stress conditions.
• Operating Temperature Range — Usable from −40 °C to 105 °C to cover a wide range of ambient conditions.
• Polarized Design — Polarized construction suitable for DC applications.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and smoothing where a 330 µF, 250 V polarized capacitor is required.
• Industrial equipment — Suitable for general-purpose roles in industrial systems that require elevated-temperature endurance and defined ripple current capability.
• Commercial power supplies — Used for energy storage and ripple attenuation in commercial power modules and assemblies operating within −40 °C to 105 °C.

Unique Advantages

• Known endurance at high temperature — Rated for 3000 hours under rated ripple at 105 °C, providing predictable aging characteristics for thermal-stressed designs.
• Frequency-aware ripple performance — Specified ripple current values at 120 Hz and 100 kHz help designers assess behavior across typical low- and high-frequency conditions.
• Compact snap-in form factor — Smaller case sizing compared with the LGU series and a compact 3.0 × 2.2 cm footprint support space-constrained board layouts.
• Wide temperature tolerance — −40 °C to 105 °C operating range accommodates diverse ambient conditions without sacrificing specified performance.
• Regulatory compliance — RoHS compliance supports environmentally conscious product design and regulatory requirements.
