LLS1K682MELB

The LLS1K682MELB is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose power applications. It provides 6.8 mF (6800 µF) capacitance at an 80 V rating in a radial can snap‑in package.

Engineered to handle sustained ripple stress, the component delivers substantial low‑ and high‑frequency ripple current capability with a 3000‑hour endurance at 85°C, making it suitable for designs that require bulk energy storage and reliable ripple handling within the specified temperature range.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance for bulk filtering and energy storage.
• High Ripple Current Capacity: Rated for 5.27 A at 120 Hz (low frequency) and 6.061 A at 50 kHz (high frequency), enabling effective smoothing of AC‑ripple and switching noise when operated within specified limits.
• Endurance & Reliability: Specified for 3000 hours at 85°C with ripple current applied; meets the LLS series endurance criteria for capacitance change, tan δ, and leakage after endurance testing.
• Electrical Losses: tan δ (loss tangent) specified at 0.20 maximum (measured at 20°C, 120 Hz) to characterize dissipation under standard test conditions.
• Leakage Current: Measured leakage current value of 2210 µA (after standard test conditions), aligned with series leakage current specifications.
• Operating Temperature Range: –40°C to +85°C suitable for a wide range of ambient conditions covered by the LLS series.
• Mechanical & Packaging: Snap‑in radial can package, size φ30 × 50L (approx. L: 5 × D: 3 cm), supplied in tray packing for production assembly and handling.
• Regulatory: RoHS compliant per the LLS series declaration.

Typical Applications

• Power supply smoothing: Bulk capacitance and high ripple current capability support DC filter and smoothing functions in power supplies operating up to 80 V.
• Switch‑mode power supplies (SMPS): High low‑ and high‑frequency ripple ratings make this part suitable for energy buffering and ripple absorption in SMPS output stages.
• Industrial power electronics: Snap‑in mounting and 3000‑hour 85°C endurance suit rack‑mounted and cabinetized equipment requiring reliable bulk storage under sustained ripple load.
• General‑purpose electronic equipment: Applicable wherever a polarized aluminum electrolytic with 6.8 mF/80 V characteristics and robust ripple handling is required.

Unique Advantages

• Substantial ripple handling: Dual ripple current specifications (5.27 A @120 Hz and 6.061 A @50 kHz) let designers account for both low‑ and high‑frequency stress in switching and line‑powered circuits.
• Long rated endurance: 3000 hours at 85°C under rated ripple current provides predictable aging behavior for lifetime planning in continuous‑duty systems.
• High voltage capability: 80 V rating enables use in higher‑voltage supply rails and applications that exceed typical low‑voltage electrolytic ranges.
• Engineered test characteristics: Specified tan δ and leakage current values (measured at 20°C, 120 Hz) give clear, testable performance metrics for design validation.
• Production‑ready packaging: Tray packing and mass production status help streamline procurement and assembly for volume manufacturing.
• Regulatory compliance: RoHS compliance supports designs targeting current environmental requirements.
