LLS2D391MELY

The LLS2D391MELY is a Nichicon LLS series aluminum electrolytic capacitor in a snap‑in terminal can, specified at 390 µF and 200 V with a ±20% capacitance tolerance. It is designed for general purpose applications that require high-voltage bulk capacitance in a compact, mechanically robust snap‑in package.

Key electrical characteristics include a dissipation factor (tanδ) of 0.15 at 20°C and 120 Hz, low- and high-frequency ripple current ratings of 1.74 A (120 Hz) and 2.61 A (50 kHz) respectively, a leakage current of 830 µA, and an endurance rating of 3000 hours at 85°C. The unit is RoHS compliant and supplied in tray packing.

Key Features

• Electrical Performance  390 µF capacitance at a 200 V rated voltage with ±20% tolerance and a tanδ of 0.15 (20°C, 120 Hz) for predictable AC loss behavior.
• Ripple Current Capability  Rated low-frequency ripple current of 1.74 A at 120 Hz and high-frequency ripple current of 2.61 A at 50 kHz to support demanding ripple conditions.
• Leakage and Polarization  Polarized electrolytic construction with a specified leakage current of 830 µA after standard conditioning.
• Reliability & Endurance  Endurance rating of 3000 hours at 85°C under rated ripple and DC bias, reflecting series-level long-term performance expectations.
• Temperature Range  Operating temperature range from −40°C to +85°C to accommodate a wide set of ambient conditions.
• Package & Mounting  Snap‑in radial can package, compact size φ20 × 35 mm, and tray packing for efficient handling and secure board retention.
• Environmental Compliance  RoHS compliant, meeting current directive requirements for restricted substances.

Typical Applications

• General-purpose power circuits  Provides bulk capacitance for smoothing and energy storage in general purpose electronic equipment that specify a 390 µF / 200 V snap‑in solution.
• DC link and filter stages  Suited to DC link and filtering roles where the combination of 200 V rating and rated ripple currents (1.74 A at 120 Hz, 2.61 A at 50 kHz) is required.
• Industrial and commercial equipment  Applicable in systems operating across −40°C to +85°C that benefit from long endurance (3000 hours at 85°C) and secure snap‑in mounting.

Unique Advantages

• High working voltage (200 V): Enables use in higher-voltage circuits without up-rating components.
• Significant ripple handling: 1.74 A (120 Hz) and 2.61 A (50 kHz) ripple current ratings support demanding AC and switching environments.
• Long endurance at elevated temperature: 3000 hours at 85°C under rated ripple and DC bias offers predictable lifetime performance.
• Compact snap‑in can: φ20 × 35 mm package with snap‑in terminals provides secure mechanical retention and efficient PCB assembly.
• Controlled dielectric losses: tanδ = 0.15 (20°C, 120 Hz) for measurable dissipation characteristics in AC applications.
• RoHS compliant: Meets current environmental substance restrictions for broad market acceptance.
