LGU2C681MELZ

The LGU2C681MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 680 µF capacitance at a 160 V rating. It is a general‑purpose, high‑voltage electrolytic designed for applications that require substantial capacitance, high ripple handling and long endurance at elevated temperatures.

Key value comes from its 105 °C endurance rating with 3000 hours of validated life under rated ripple conditions, compact φ22×40 mm can size, and RoHS compliance—making it suitable where reliable bulk capacitance and sustained ripple performance are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 160 V rated voltage suitable for high‑voltage general‑purpose designs.
• Snap‑in Terminal Mount — Radial, can snap‑in package for secure panel or chassis mounting and straightforward assembly in power products.
• High‑Temperature Endurance — Rated for 3000 hours at 105 °C under DC bias plus rated ripple current; designed to meet LGU series endurance requirements.
• Ripple Current Capability — Low‑frequency ripple current of 1.82 A at 120 Hz and high‑frequency ripple current of 2.73 A at 50 kHz, supporting continuous ripple handling across common power frequencies.
• Low Loss — tanδ (DF) of 0.15 measured at 20 °C, 120 Hz (for the 160 V rating range), indicating controlled dissipation for stable operation.
• Leakage Current — Specified leakage current of 980 µA after voltage application at 20 °C, enabling predictable bias behavior in designs.
• Operating Temperature Range — −40 °C to +105 °C for broad environmental compatibility in industrial and general‑purpose equipment.
• Regulatory — RoHS compliant to applicable directives.
• Packaging — Supplied in tray packing for handling and assembly convenience.

Typical Applications

• General‑purpose power systems — Provides bulk capacitance for general‑purpose power designs requiring 160 V class electrolytic support.
• Power supply filtering — Used where high capacitance and verified ripple endurance at 105 °C are needed to stabilize DC rails.
• Industrial equipment — Suited to general industrial applications that require sustained operation at elevated temperatures and high ripple stress.

Unique Advantages

• Long, validated endurance: 3000 hours at 105 °C under rated ripple stress provides predictable life for designs exposed to high temperatures.
• High ripple handling across frequencies: Specified ripple current at both low (1.82 A at 120 Hz) and high (2.73 A at 50 kHz) frequencies supports a range of power converters and regulators.
• Controlled dissipation: Low tanδ (0.15 at 160 V rating) helps limit heating and energy loss in continuous operation.
• Compact snap‑in package: φ22×40 mm can in a snap‑in, radial configuration simplifies mounting in chassis and power assemblies.
• predictable leakage behavior: Specified leakage current (980 µA) for stable bias performance after voltage application.
• RoHS compliant and tray packed: Facilitates regulatory compliance and efficient handling during production.
