LLS2V391MELA

The LLS2V391MELA is a snap‑in aluminum electrolytic capacitor rated at 350 V with a nominal capacitance of 390 µF and a tolerance of −20% to +20%. It is supplied in a radial can snap‑in package (φ25 × 40 mm) and packaged for tray handling.

Designed for general‑purpose applications, the part combines high voltage capability, measurable ripple current performance, and a 3000‑hour endurance at 85°C to support demanding power filtering and energy‑storage roles where polarized electrolytic capacitance is required.

Key Features

• Capacitance & Voltage: 390 µF nominal capacitance with −20%/+20% tolerance and a rated voltage of 350 V.
• Package & Mounting: Snap‑in terminal (radial can, snap‑in) sized φ25 × 40 mm and supplied in tray packing for efficient assembly.
• Ripple Current Performance: Low‑frequency ripple current 2.14 A at 120 Hz and high‑frequency ripple current 3.06 A at 50 kHz, specified for the part.
• Dissipation Factor (tan δ): tan δ = 0.15 (measured at 20°C, 120 Hz) indicating the specified loss characteristic at test conditions.
• Leakage Current: Specified leakage current of 1100 µA after standard voltage application conditions.
• Endurance & Reliability: Rated to withstand 3000 hours with rated ripple current at 85°C; endurance criteria include capacitance change within ±20% and leakage not exceeding initial specified value after test.
• Operating Temperature: Specified temperature range −25°C to +85°C, matching the 350 V category requirements.
• Environmental Compliance: RoHS compliant.

Typical Applications

• General Purpose: Suitable for general‑purpose circuits that require polarized aluminum electrolytic capacitance at 350 V.
• Power Filtering and Smoothing: Use where sustained ripple current handling is required; datasheet ripple current figures (2.14 A at 120 Hz, 3.06 A at 50 kHz) indicate capability for filtering duties.
• High‑ripple Environments: Engineered for extended ripple exposure with a 3000‑hour endurance rating at 85°C when subjected to rated ripple current.

Unique Advantages

• High Voltage Capability: 350 V rating enables use in higher‑voltage DC rails and power systems that require robust voltage handling.
• Measured Ripple Performance: Explicit low‑ and high‑frequency ripple current specifications support predictable thermal and lifetime behavior in design calculations.
• Long Endurance at Elevated Temperature: 3000 hours at 85°C under rated ripple conditions provides defined reliability margins for long‑running power applications.
• Clear Loss Characteristic: tan δ = 0.15 (20°C, 120 Hz) gives a verifiable dissipation figure for AC loss budgeting and thermal planning.
• Tray Packing for Production: Supplied in tray packing to support automated assembly and inventory handling.
• RoHS Compliant: Meets RoHS requirements for regulated materials compliance.
