LGU1V123MELC

The LGU1V123MELC from Nichicon is a snap-in, radial can aluminum electrolytic capacitor in the LGU series, rated for 35 V and 12,000 µF (±20%). Designed for 105°C operation, this part delivers high bulk capacitance in a compact φ35 × 30 mm package with snap-in mounting for robust PCB installation.

Its combination of large capacitance, rated ripple-current capability and a 3,000-hour endurance at 105°C makes it suited to general-purpose power conditioning and bulk energy storage in equipment that requires durable, long-life electrolytic capacitance.

Key Features

• High Capacitance: 12,000 µF nominal capacitance with tolerance −20% to +20% for bulk energy storage and smoothing.
• Rated Voltage: 35 V DC rating suitable for mid-voltage power rails and power-supply filtering.
• Temperature and Endurance: Operating range −40°C to +105°C with a guaranteed lifetime of 3,000 hours at 105°C under rated ripple conditions.
• Ripple Current Capability: Low-frequency ripple current 3.2 A at 120 Hz and high-frequency ripple current 3.68 A at 50 kHz, supporting sustained AC stress on power rails.
• Dielectric Loss and Leakage: tanδ = 0.35 (measured at 20°C, 120 Hz) and leakage current 1,940 µA, specified after rated voltage application.
• Package & Mounting: Snap-in radial can (φ35 × 30 mm body) designed for secure mechanical retention on PCBs; supplied in tray packing for production handling.
• Compliance & Availability: RoHS compliant and listed as mass production status in the LGU series.

Typical Applications

• Power-supply filtering and bulk smoothing: Large 12,000 µF capacitance and rated ripple currents (3.2 A @ 120 Hz, 3.68 A @ 50 kHz) provide effective smoothing and energy buffering on DC power rails.
• General-purpose industrial equipment: 105°C rating and 3,000-hour endurance support long-term operation in demanding ambient conditions for general-purpose designs.
• Energy-hold and decoupling: High capacitance in a compact radial can enables bulk decoupling and short-term energy hold for intermediate power bus stabilization.

Unique Advantages

• Long endurance at elevated temperature: 3,000 hours rated life at 105°C offers predictable service life under continuous thermal and ripple stress.
• Robust ripple handling: Specified ripple currents at both low and high frequencies let designers account for AC stress across a range of switching and line frequencies.
• Compact high-capacitance package: φ35 × 30 mm can delivers 12,000 µF in a space-efficient footprint for designs constrained by board area.
• Secure snap-in mounting: Radial snap-in terminals simplify mechanical retention for vertical PCB mounting and production insertion.
• Production-ready supply: Tray packing and mass-production status facilitate integration into manufacturing workflows.
• Regulatory compliance: RoHS compliance supports deployment in environmentally regulated assemblies.
