LLG2C332MELC45

The LLG2C332MELC45 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LLG series. It delivers 3.3 mF (3300 µF) at 160 V in a compact φ35 × 45 mm snap-in can designed for general purpose applications.

Built for equipment downsizing, this LLG-series part combines high ripple-current capability, a low loss angle, and a 2000-hour endurance rating at 85°C, making it suitable for designs that require reliable DC-link or bulk energy storage in a smaller case footprint.

Key Features

• Capacitance and Voltage — 3.3 mF (3300 µF) rated at 160 V to support substantial bulk energy storage in a single component.
• Snap-In Can Package — Radial, snap-in terminal construction in a φ35 × 45 mm can for secure board mounting and mechanical stability.
• High Ripple Current Handling — Rated ripple currents of 5.75 A at 120 Hz (low frequency) and 8.625 A at 100 kHz (high frequency) to manage significant AC ripple loads.
• Low Loss Angle — tan δ ≤ 0.15 (measured at 120 Hz, 20°C) for reduced dielectric losses under normal operating conditions.
• Leakage Current — Specified leakage current of 2170 µA after voltage application, consistent with electrolytic performance expectations.
• Endurance and Temperature Range — 2000 hours life at 85°C and an operating range of −40°C to +85°C for sustained reliability in thermal environments within this range.
• Tolerance and Polarization — ±20% capacitance tolerance at 120 Hz, 20°C; polarized device for correct circuit orientation.
• Compliance and Production — RoHS compliant and supplied in tray packing suitable for mass production.
• Compact Series Design — LLG series offers a one-rank-smaller case size compared with the LLS series, aiding equipment downsizing efforts.

Typical Applications

• General Purpose Electronics — Provides bulk capacitance where a 3.3 mF, 160 V snap-in solution is required for general purpose circuits.
• Equipment Downsizing — The smaller LLG case size supports designs that need reduced component footprint without sacrificing capacitance.
• High-Ripple Environments — Suited for circuits that must tolerate significant ripple currents, given its specified ripple ratings at both low and high frequencies.
• Production-Ready Assemblies — Tray packing and RoHS compliance make it appropriate for high-volume manufacturing workflows.

Unique Advantages

• High Energy Density in a Smaller Can — 3.3 mF at 160 V in a φ35 × 45 mm package helps maximize stored energy while minimizing board area.
• Robust Ripple Current Capability — Dual-frequency ripple specifications (5.75 A at 120 Hz and 8.625 A at 100 kHz) help maintain performance under substantial AC stress.
• Controlled Losses — tan δ ≤ 0.15 (120 Hz, 20°C) reduces internal dissipation for better thermal behavior in end-use systems.
• Endurance at Elevated Temperature — 2000-hour rating at 85°C provides a measurable reliability baseline for thermal endurance planning.
• Manufacturing-Friendly — Snap-in terminals and tray packing support efficient assembly and handling for mass-production environments.
• Regulatory Compliance — RoHS compliance aligns with modern production and environmental requirements.
