LLG2G561MELC35

The LLG2G561MELC35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLG series, providing 560 µF of capacitance at a 400 V rating in a compact radial can. It is designed for general-purpose applications that require high-voltage smoothing and energy storage with a smaller case footprint and snap-in mounting for secure PCB installation.

Key value comes from its combination of high voltage capability, strong ripple-current handling, and a 2000-hour endurance at 85°C, making it suitable for production environments where compactness, repeatable performance, and RoHS compliance matter.

Key Features

• Electrical Performance: 560 µF capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Loss (tan δ): Maximum tan δ of 0.15 at rated voltage, measured at 120 Hz and 20°C, supporting stable AC performance.
• High Ripple Current Capability: Rated ripple current of 2.390 A at 120 Hz (low frequency) and 3.4177 A at 100 kHz (high frequency).
• Leakage Current: Specified leakage current of 1,410 µA (after 5 minutes’ application of rated voltage at 20°C as per product data).
• Reliability / Lifetime: Endurance specified as 2000 hours at 85°C under D.C. bias plus rated ripple current with limits on capacitance change, tan δ, and leakage current.
• Mechanical / Package: Snap-in terminal radial can in a φ35 × 35 mm size; supplied in tray packing for mass production handling.
• Temperature Range: Rated for operation from −25°C to +85°C for the 400 V variants.
• Regulatory Compliance: RoHS compliant.
• Polarized Construction: Polarized electrolytic design appropriate for power and smoothing circuits requiring DC polarity.

Typical Applications

• General-purpose power systems: Provides bulk capacitance and smoothing in equipment that requires a 560 µF, 400 V polarized snap-in capacitor.
• Compact equipment / downsized designs: One rank smaller case size compared with the LLS series, suited for equipment downsizing where board space and height constraints matter.
• High-voltage power supplies: 400 V rating supports high-voltage DC bus filtering and energy storage in industrial and power electronics equipment.
• Production assemblies: Snap-in radial design and tray packing support automated handling and mass production workflows.

Unique Advantages

• Compact snap-in form factor: φ35 × 35 mm radial can and snap-in terminals enable secure mounting while reducing case size compared with larger family members.
• High-voltage capability: 400 V rating lets designers address higher-voltage DC buses without parallel capacitor networks.
• Robust ripple handling: Rated ripple currents of 2.390 A (120 Hz) and 3.4177 A (100 kHz) support demanding AC-loading conditions.
• Durability at elevated temperature: 2000-hour endurance at 85°C ensures sustained performance under prolonged thermal stress.
• Predictable leakage and loss: Specified leakage current (1,410 µA) and conservative tan δ (0.15) allow predictable behavior in power circuits.
• RoHS compliant and production-ready: Conforms to RoHS and is supplied in tray packing for streamlined manufacturing integration.
