LLS2W820MELY

The LLS2W820MELY is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose high-voltage applications. It delivers 82 µF capacitance at a 450 V rating in a compact snap-in radial can.

Built for circuits that require sustained ripple handling and long-term endurance, this Nichicon part offers defined leakage, loss tangent, and temperature endurance characteristics suitable for mass-production assemblies with tray packing.

Key Features

• Electrical performance — 82 µF capacitance with ±20% tolerance and a rated voltage of 450 V, suitable for high-voltage DC circuits.
• Loss and leakage — tanδ (DF) of 0.2 at 20°C and 120 Hz and a specified leakage current of 570 µA, providing predictable dissipation and leakage behavior.
• Ripple current capability — 800 mA low-frequency ripple current at 120 Hz and 1.144 A high-frequency ripple current at 50 kHz for robust AC load handling.
• Endurance — Rated for 3000 hours at 85°C under DC bias plus rated ripple current, supporting extended operational life in elevated-temperature environments.
• Operating range — Specified operating temperature from −25°C to 85°C.
• Package & mounting — Snap-in terminal, radial can (φ20 × 35 mm), designed for secure board mounting and straightforward assembly; delivered in tray packing for production workflows.
• Compliance — RoHS compliant.

Typical Applications

• Power supplies — Bulk filtering and smoothing in general-purpose power supply designs that require a 450 V-rated capacitor with high ripple current capability.
• Industrial power modules — Energy-storage and decoupling for general-purpose industrial power electronics where long endurance at 85°C is required.
• High-voltage DC circuits — General-purpose high-voltage filtering and stabilization tasks that benefit from a compact, snap-in radial can form factor.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher DC-voltage designs without changing capacitor family.
• Predictable AC performance: Specified ripple currents at both 120 Hz (800 mA) and 50 kHz (1.144 A) allow designers to size capacitors against measured AC stresses.
• Long endurance at elevated temperature: 3000 hours at 85°C under rated conditions supports reliable operation in warm operating environments.
• Compact, assembly-friendly package: φ20 × 35 mm snap-in radial can with tray packing simplifies mounting and production handling.
• Measured dielectric behavior: Tangent of loss angle (tanδ) 0.2 at 20°C/120 Hz provides a clear parameter for thermal and loss budgeting.
• RoHS compliant: Conforms to RoHS requirements for regulatory-compliant designs.
