LGU2C681MELB

The LGU2C681MELB is a Nichicon LGU series snap-in aluminum electrolytic capacitor rated at 160 V and 680 µF. It is a polarized, radial can (snap-in) type designed for general-purpose electronic applications that require a compact electrolytic solution with specified ripple handling and high-temperature endurance.

Key value propositions include a 105°C operating temperature range with a 3000-hour endurance at 105°C, measurable low and high-frequency ripple current capability, and RoHS compliance for regulated designs.

Key Features

• Electrical Performance 680 µF capacitance with a tolerance of −20% to +20% and a rated voltage of 160 V. Specified tangent of loss angle (tanδ) is 0.15 measured at 20°C, 120 Hz.
• Ripple Current Capability Low-frequency ripple current specified at 1.82 A (120 Hz) and high-frequency ripple current at 2.73 A (50 kHz), enabling use where AC ripple handling is required.
• Leakage Current Rated leakage current of 980 µA (after specified conditions), supporting predictable DC leakage behavior in designs.
• High-Temperature Endurance Designed to withstand 3000 hours at 105°C under rated ripple current and DC bias conditions per the LGU series specification.
• Package and Mounting Snap-in terminal radial can (φ30 × 25 mm) for secure board mounting; supplied in tray packing for production assembly.
• Operating Range and Polarization Polarized capacitor with an operating temperature range of −40°C to +105°C.
• Environmental Compliance RoHS compliant as specified in the LGU series documentation.

Typical Applications

• General-purpose electronic equipment — Suitable where a 160 V, 680 µF snap-in electrolytic capacitor is required for bulk capacitance and energy buffering in general-purpose designs.
• Circuits requiring specified ripple handling — Appropriate for applications that need defined low- and high-frequency ripple current capability (1.82 A at 120 Hz, 2.73 A at 50 kHz).
• High-temperature environments — Applicable to equipment designs that require continuous operation up to 105°C with a 3000-hour endurance specification.

Unique Advantages

• Rated for 105°C endurance: The LGU2C681MELB meets the LGU series specification of 3000 hours at 105°C, providing predictable long-term performance under elevated temperature conditions.
• Defined ripple performance: Low- and high-frequency ripple current ratings (1.82 A @120 Hz and 2.73 A @50 kHz) allow designers to size capacitance for AC ripple requirements with specification-backed numbers.
• Compact snap-in form factor: φ30 × 25 mm radial can with snap-in terminals simplifies board mounting and mechanical retention for through-hole assembly.
• Measured dielectric loss: tanδ of 0.15 (20°C, 120 Hz) at the 160 V rating supports predictable dissipation behavior in AC and pulsed applications.
• RoHS compliant: Meets RoHS directive requirements as called out in the LGU series documentation, aiding regulatory compliance for assemblies.
• Production-ready packaging: Supplied in tray packing and listed as mass production status for volume procurement and assembly.
