LLS2V681MELC

The LLS2V681MELC is a Nichicon LLS series snap-in aluminum electrolytic capacitor rated at 680 µF and 350 V. It is a radial, snap-in terminal type designed for general-purpose power applications that require high-voltage capacitance in a compact, board-mounted can.

Key value comes from its high ripple-current capability and long endurance: tested to withstand 3,000 hours of rated ripple current at 85°C, making it suitable for designs where sustained ripple and elevated operating temperature must be addressed.

Key Features

• Capacitance and Voltage 680 µF nominal capacitance with a 350 V rated voltage and ±20% tolerance measured at 120 Hz, 20°C.
• High Ripple-Current Endurance Rated ripple current of 3.15 A at 120 Hz (low frequency) and 4.505 A at 50 kHz (high frequency), with endurance testing for 3,000 hours at 85°C under DC bias plus rated ripple.
• Loss Characteristics Tangent of loss angle (tan δ) specified at 0.15 (measurement condition: 20°C, 120 Hz), indicating defined dissipation behavior at rated voltage.
• Leakage Current Manufacturing-specified leakage current: 1,460 µA (measured after 5 minutes application of rated voltage at 20°C, per series specification formulas).
• Temperature Range and Endurance Operates from –25°C to +85°C with endurance validated to 3,000 hours at 85°C when subjected to rated ripple and DC bias.
• Snap-in Radial Can Package φ35 × 40 mm length (L: 4 × D: 3.5 cm) radial snap-in package for secure mounting and mechanical stability on PCBs; tray packing for production handling.
• Regulatory Status RoHS compliant.
• Production Status Mass production availability from the Nichicon LLS series.

Typical Applications

• Power Supplies Used for bulk filtering and smoothing in high-voltage power supplies where 350 V rating and high ripple endurance are required.
• Industrial Power Electronics Applicable in industrial equipment that requires robust high-voltage capacitance and sustained ripple handling at elevated temperatures.
• Energy Systems and UPS Suitable for energy-storage smoothing and DC-link support in systems that demand stable capacitance and long endurance under ripple stress.

Unique Advantages

• High-Voltage Capability: 350 V rating enables use in higher-voltage designs without series stacking.
• Validated Ripple Endurance: Specified ripple currents of 3.15 A (120 Hz) and 4.505 A (50 kHz) plus 3,000-hour endurance at 85°C provide predictable behavior under sustained ripple stress.
• Defined Dissipation Behavior: tan δ = 0.15 (20°C, 120 Hz) gives a clear measure of dielectric losses for thermal and efficiency planning.
• Production-Ready Packaging: Tray packing and mass production status simplify procurement and assembly for volume builds.
• RoHS Compliance: Conforms to RoHS directives for environmental and regulatory alignment.
• Compact Snap-in Form Factor: φ35 × 40 mm radial can with snap-in terminals provides a secure PCB mount and space-efficient high-voltage capacitance.
