LLS2Z681MELZ

The LLS2Z681MELZ is a Nichicon LLS series aluminum electrolytic capacitor in a snap-in terminal radial can. It provides 680 µF capacitance at a 180 V rating with a ±20% tolerance and is intended for general-purpose power applications that require bulk energy storage and ripple handling.

Designed for sustained operation up to 85°C, this snap-in module combines high ripple-current capability with long endurance to support production assemblies and industrial power systems where reliable DC filtering and decoupling are required.

Key Features

• Capacitance and Voltage: 680 µF rated capacitance at 180 V for bulk filtering and energy storage in mid-voltage power rails.
• Tolerance: ±20% capacitance tolerance measured at 120 Hz and 20°C, enabling predictable sizing for power designs.
• Low Loss (tan δ): tanδ 0.15 measured at 20°C and 120 Hz, indicating controlled dielectric losses at common line-frequency testing conditions.
• High Ripple Current Capacity: Low-frequency ripple current 2.48 A (120 Hz) and high-frequency ripple current 3.72 A (50 kHz), supporting both mains-frequency smoothing and higher-frequency switching environments.
• Leakage Current: Rated leakage current 1040 µA after voltage application, suitable for power systems where controlled leakage is required.
• Endurance: Life rating of 3000 hours at 85°C with rated ripple current applied, reflecting sustained performance under elevated temperature and ripple stress.
• Operating Temperature Range: –40°C to +85°C for operation across common industrial temperature conditions.
• Package and Mounting: Snap-in radial can (φ22 × 35 mm body), aimed at secure chassis or PCB mounting and compatible with tray packing for mass production handling.
• Regulatory Compliance: RoHS-compliant construction consistent with modern environmental requirements.

Typical Applications

• Power Supply Filtering: Bulk smoothing and DC link filtering on 180 V rails, leveraging the 680 µF capacitance and rated ripple current for reduced voltage ripple.
• Switch-Mode Power Supplies (SMPS): Decoupling and energy buffering for mid-voltage converters where both low-frequency and high-frequency ripple handling are needed.
• Industrial Power Electronics: Long-life filtering and decoupling in industrial control equipment that operates up to 85°C and benefits from the capacitor’s 3000-hour endurance.
• General-Purpose Power Modules: Energy storage and smoothing in a variety of general-purpose electronic assemblies requiring a robust snap-in capacitor solution.

Unique Advantages

• High Ripple Endurance: Separate low- and high-frequency ripple ratings (2.48 A @ 120 Hz and 3.72 A @ 50 kHz) provide measurable capability for both mains-frequency and switching-frequency stress.
• Long Rated Life at Elevated Temperature: 3000 hours endurance at 85°C with rated ripple current applied, supporting durability in continuous-duty applications.
• Low Loss Characteristics: tanδ of 0.15 at 120 Hz and 20°C helps minimize dissipation under line-frequency excitation, aiding thermal management.
• Secure Snap-In Mounting: Radial, snap-in can package simplifies mechanical integration into assemblies and supports tray packing for production workflows.
• RoHS Compliance: Environmentally compliant materials for designs requiring RoHS-conformant components.
• Manufacturer Series Reliability: Part of the Nichicon LLS snap-in series, offering consistent specification sets such as category temperature range and rated voltage tolerance across the series.
