LLG2E391MELZ30

The LLG2E391MELZ30 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LLG series, designed for compact, general-purpose power applications. As a radial, can-style snap-in component, it delivers a combination of high voltage handling (250 V), significant capacitance (390 µF) and rated ripple capability for robust power-filtering performance.

Built for production use, this part offers a 2000 hour endurance at 85°C, RoHS compliance and tray packing for streamlined assembly, making it suitable for equipment designs that require reliable, compact bulk capacitance.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance at a rated voltage of 250 V with ±20% tolerance (120 Hz, 20°C).
• High ripple current capability — Rated ripple currents of 1.91 A at 120 Hz and 2.865 A at 100 kHz support effective AC ripple smoothing.
• Low loss and leakage — Tangent of loss angle (tan δ) specified at 0.15 (120 Hz, 20°C) and measured leakage current of 930 µA for predictable DC performance.
• Endurance at elevated temperature — 2000 hours life rating at 85°C under D.C. bias plus rated ripple current to ensure stability over extended operation.
• Compact, snap-in package — φ22 × 30 mm can size with snap-in radial terminals for secure PCB mounting and space-efficient designs; LLG series is one rank smaller than LLS to aid equipment downsizing.
• Operating temperature range — Specified for –40°C to +85°C to cover a wide range of environmental conditions.
• Manufacturing readiness — Tray packing and mass production status for straightforward integration into volume assemblies.
• Regulatory compliance — RoHS compliant.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and ripple smoothing where a 250 V, 390 µF snap-in solution is required.
• Space-constrained designs — The smaller-sized LLG series package helps reduce enclosure and board area in compact systems.
• Boards requiring secure mounting — Snap-in terminals offer reliable retention for assemblies that undergo handling or vibration during manufacture and use.

Unique Advantages

• High ripple handling: Dual ripple ratings (1.91 A at 120 Hz and 2.865 A at 100 kHz) enable effective filtering across low and high frequency ripple conditions.
• Predictable electrical behavior: Specified tan δ of 0.15 and measured leakage current of 930 µA provide clear parameters for circuit design and margining.
• Durability at elevated temperature: 2000 hours endurance at 85°C ensures stability of capacitance, dissipation factor and leakage after extended high-temperature operation.
• Compact form factor: φ22 × 30 mm can and one-rank-smaller LLG series sizing support equipment downsizing without sacrificing voltage or capacitance.
• Production-friendly packaging: Tray packing and mass production availability simplify procurement and assembly for volume manufacturing.
• RoHS compliant: Meets RoHS directive requirements for environmentally compliant designs.
