LLS2W121MELY

The LLS2W121MELY is an aluminum electrolytic capacitor in a snap-in terminal can, part of Nichicon's LLS series. It delivers 120 µF capacitance at a 450 V rating with ±20% tolerance and is designed for general-purpose power applications that require high-voltage bulk capacitance and robust ripple handling.

Key design attributes include snap-in mounting for secure board retention, a compact φ20 × 40 mm can size, a 3000 hour endurance rating at 85°C, and RoHS compliance—making it suitable for production designs that prioritize long-term reliability and predictable electrical performance.

Key Features

• Rated Capacitance and Tolerance: 120 µF with ±20% tolerance at 120 Hz and 20°C for predictable charge storage and design margin.
• High Voltage: Rated voltage 450 V to support high-voltage DC bus and power applications.
• Snap-in Terminal Package: Radial, can-type snap-in mounting for secure mechanical retention and easy insertion into production assemblies; supplied in tray packing for mass production.
• Endurance: 3000 hours at 85°C under rated conditions, meeting the LLS series endurance specification.
• Ripple Current Capability: 990 mA at 120 Hz (low frequency) and 1.416 A at 50 kHz (high frequency) to handle applied AC ripple across frequencies.
• Low Loss Characteristic: tan δ of 0.2 (measured at 20°C, 120 Hz) to limit dissipation in AC and ripple conditions.
• Leakage Current: 690 µA specified leakage current for predictable standby behavior after voltage application.
• Operating Temperature Range: –25°C to 85°C to match the LLS series temperature window for 350–450 V parts.
• RoHS Compliant: Meets RoHS directive requirements as indicated for the LLS series.

Typical Applications

• General Purpose Power Systems: Provides high-voltage bulk capacitance and smoothing in designs that require a 450 V, 120 µF electrolytic solution.
• High-Voltage DC Bus Filtering: Handles ripple current at both low and high frequencies to stabilize DC bus rails where endurance at 85°C is required.
• Industrial Power Electronics: Snap-in mounting and tray packing support production assembly of industrial power supplies and related equipment needing long-life capacitors.

Unique Advantages

• High-Voltage Capability: 450 V rating enables use in higher-voltage power designs without additional series stacking.
• Long Endurance at Elevated Temperature: 3000 hour rating at 85°C supports sustained operation under thermal stress for predictable lifetime planning.
• Broad Ripple Performance: Specified ripple current at 120 Hz and at 50 kHz gives designers quantifiable margins across frequency ranges.
• Secure Snap-in Mounting: Radial, snap-in can simplifies mechanical retention and assembly for high-throughput manufacturing.
• Compact Footprint: φ20 × 40 mm can size provides high-voltage capacitance in a compact package for space-constrained boards.
• Regulatory Compliance: RoHS status supports environmental compliance requirements in production products.
