LLS2E681MELA

The LLS2E681MELA is a Nichicon LLS-series aluminum electrolytic capacitor in a snap-in, radial can package. It provides 680 µF capacitance at a 250 V rating with polarization and ±20% tolerance, targeting general-purpose electrical and electronic applications that require bulk capacitance and sustained ripple handling.

Designed for robust operation across a wide temperature range, this part is specified for -40°C to +85°C, offers 3000 hours of endurance at 85°C under rated ripple conditions, and is RoHS compliant.

Key Features

• Electrical Rating — 680 µF nominal capacitance at a 250 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Loss Characteristic — tan δ ≤ 0.15 at 20°C and 120 Hz for the 250 V rating, supporting efficient AC ripple handling.
• High Ripple Current Capability — 2.67 A rated ripple current at 120 Hz (low frequency) and 4.005 A at 50 kHz (high frequency), enabling sustained AC stress performance.
• Leakage Current — Specified leakage current of 1230 µA.
• Endurance — Rated for 3000 hours at 85°C with DC bias plus rated ripple current applied, per series endurance specification.
• Thermal Range — Operates from -40°C to +85°C, suitable for a wide range of ambient conditions.
• Package & Mounting — Snap-in terminal, radial can package (φ25 × 40 mm / L: 4 × D: 2.5 cm) supplied in tray packing for production assembly.
• Compliance — RoHS compliant material status.

Typical Applications

• General Purpose Power Electronics — Bulk capacitance for smoothing and energy storage in general-purpose circuits where 250 V, 680 µF is required.
• Power Supply Filtering — Handles rated ripple currents (2.67 A at 120 Hz; 4.005 A at 50 kHz) for AC ripple suppression in power supplies and converters.
• Industrial Equipment — Long endurance (3000 hours at 85°C) and wide operating temperature (-40°C to +85°C) for sustained operation in industrial environments.

Unique Advantages

• High Voltage Bulk Capacitance: 680 µF at 250 V provides substantial stored energy per component for designs needing compact bulk capacitance.
• Robust Ripple Performance: Dual-frequency ripple ratings (120 Hz and 50 kHz) show the capacitor’s capability to handle both low- and high-frequency AC stress.
• Proven Endurance: 3000-hour rating at 85°C under rated ripple conditions supports reliability in continuous-operation applications.
• Low Dissipation Factor: tan δ ≤ 0.15 at 20°C/120 Hz reduces heat generation under AC conditions and supports thermal stability.
• Production-Ready Packaging: Tray packing and snap-in mounting simplify assembly for mass-production environments.
• Regulatory Compliance: RoHS compliance supports use in regions and products with restricted substance requirements.
