LLS2C681MELA

The LLS2C681MELA is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for general‑purpose applications. It provides 680 µF capacitance at a 160 V rated voltage with ±20% tolerance and is part of Nichicon's LLS series.

Key electrical and reliability attributes include a tanδ of 0.15 (measured at 20°C, 120 Hz), rated ripple current capability at both low and high frequencies, a leakage current of 980 µA, and an endurance rating of 3000 hours at 85°C. The part is RoHS compliant and supplied in tray packing for mass production use.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance for general‑purpose energy storage and decoupling where higher voltage handling is required.
• Tangent of loss angle (tan δ) — tanδ ≤ 0.15 at 20°C and 120 Hz, providing a defined dissipation characteristic for AC and ripple conditions.
• Ripple Current Handling — Rated ripple current of 2.33 A at 120 Hz (low frequency) and 3.495 A at 50 kHz (high frequency), supporting sustained AC loading within specifications.
• Leakage Current — Specified leakage current of 980 µA, measured under the product’s stated test conditions.
• Endurance — Designed to withstand 3000 hours of rated ripple current at 85°C while meeting endurance limits for capacitance change, tanδ, and leakage current as specified by the series.
• Operating Temperature Range — −40°C to +85°C, suitable for a wide range of ambient operating conditions covered by the LLS series.
• Package & Mounting — Snap‑in radial can construction, physical size φ25 × 30 L (L: 3 × D: 2.5 cm), optimized for secure mounting in power assemblies; supplied in tray packing for production handling.
• Environmental Compliance — RoHS compliant.
• Polarized — Polar capacitor requiring correct polarity in application.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and ripple current capability for power supply filtering and energy storage in general‑purpose designs.
• Industrial power equipment — Snap‑in mounting and 160 V rating suit assemblies where compact, durable capacitors are required for sustained ripple loading.
• Mass-production assemblies — Tray packing and mass production status facilitate high-volume manufacturing and board‑level integration.

Unique Advantages

• High voltage capability: 160 V rating allows use in higher‑voltage DC circuits without series stacking.
• Defined ripple performance: 2.33 A (120 Hz) and 3.495 A (50 kHz) ripple ratings enable predictable operation under both low‑ and high‑frequency ripple conditions.
• Long endurance at elevated temperature: 3000 hours at 85°C endurance provides a quantifiable lifecycle for thermal and ripple‑loaded applications.
• Compact snap‑in form factor: φ25×30L radial can with snap‑in terminals simplifies secure PCB or chassis mounting in power modules.
• Controlled dielectric loss: tanδ ≤ 0.15 at 120 Hz and 20°C for stable dissipation characteristics.
• Regulatory compliance: RoHS compliant for environmentally conscious manufacturing.
