LGU2F181MELA

The LGU2F181MELA from Nichicon is a snap-in, radial aluminum electrolytic capacitor providing 180 µF nominal capacitance at a 315 V rating. It is designed for general-purpose power applications that require high-voltage bulk capacitance with robust ripple endurance and long-term stability.

Key value comes from its 105°C endurance rating and snap-in packaging, delivering dependable bulk energy storage and smoothing in assemblies where compact, serviceable power capacitors are required.

Key Features

• Electrical Rating — 180 µF capacitance with a 315 V rated voltage and tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low-loss Performance — tanδ (loss tangent) 0.15 at 20°C and 120 Hz for stable dissipation characteristics at the rated voltage.
• Ripple Current Capability — Low-frequency ripple current 920 mA at 120 Hz and high-frequency ripple current 1.316 A at 50 kHz, supporting sustained AC stress handling.
• Leakage Current — Specified leakage current of 710 µA (per the datasheet leakage current test conditions).
• High-temperature Endurance — Rated to withstand 3000 hours of rated ripple current at 105°C, per LGU series specifications.
• Operating Temperature Range — Specified for -25°C to 105°C for 315 V products.
• Mechanical & Package — Snap-in radial can (φ25 × 25L) for secure panel/board retention; supplied in tray packing for assembly handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance and smoothing in power assemblies where a 315 V rating and 180 µF are required.
• High-temperature power environments — Circuits that require sustained ripple endurance at elevated temperatures up to 105°C.
• Panel- and chassis-mounted power modules — Snap-in radial can design enables secure mounting in power supply and industrial equipment enclosures.

Unique Advantages

• 315 V high-voltage capacity: Provides substantial bulk energy storage at a 315 V rating for high-voltage power rails.
• Proven high-temperature endurance: Designed to withstand 3000 hours of rated ripple current at 105°C, supporting long-term reliability under thermal stress.
• Frequency-flexible ripple handling: Specified ripple current at both 120 Hz (920 mA) and 50 kHz (1.316 A) for effectiveness across low- and high-frequency applications.
• Compact, serviceable form factor: φ25 × 25L snap-in radial can balances capacitance and footprint for space-conscious power designs and straightforward assembly.
• Measured electrical stability: Low loss (tanδ 0.15 at 120 Hz, 20°C) and a defined leakage current (710 µA) enable predictable performance during design and test.
• Regulatory compliance: RoHS compliance supports environmentally conscious product builds.
