LGU2Z681MELZ

The LGU2Z681MELZ is a Nichicon LGU series aluminum electrolytic capacitor with a snap‑in terminal configuration, rated at 180 V and 680 µF (±20%). It delivers low dissipation (tanδ 0.15 at 20°C, 120 Hz), high ripple‑current capability, and a 3000‑hour endurance at 105°C for reliable long‑term operation.

Designed for general‑purpose applications that require bulk capacitance, robust ripple handling and stable performance across a wide temperature range (‑40°C to 105°C), this radial can (snap‑in) package is offered in tray packing and is in mass production.

Key Features

• Capacitance & Voltage: 680 µF rated capacitance at 180 V with ±20% tolerance, suitable for applications needing significant bulk energy storage.
• Low Loss Characteristics: tanδ = 0.15 max measured at 20°C, 120 Hz, supporting improved efficiency and lower heat generation in AC ripple environments.
• High Ripple‑Current Capability: 1.78 A at 120 Hz (low frequency) and 2.67 A at 50 kHz (high frequency), enabling effective smoothing and decoupling under AC stress.
• Leakage Current: Specified leakage current of 1040 µA after rated voltage application, allowing predictable bias behavior for charged circuits.
• Endurance: Rated for 3000 hours at 105°C with defined limits for capacitance change, tanδ and leakage current after the endurance test.
• Operating Temperature Range: –40°C to 105°C, supporting operation across wide ambient conditions.
• Package & Mounting: Snap‑in radial can (φ22 × 45 mm) for secure chassis or panel mounting; provided in tray packing for production handling.
• Compliance & Production Status: RoHS compliant and in mass production.

Typical Applications

• General‑purpose power systems: Bulk energy storage and smoothing where 180 V rated capacitance and high ripple handling are required.
• Industrial electronics: Circuits that demand stable performance at elevated temperatures and significant ripple currents.
• High‑frequency filtering: Applications benefiting from specified high‑frequency ripple current capability up to 50 kHz.

Unique Advantages

• High ripple tolerance: Specified 1.78 A (120 Hz) and 2.67 A (50 kHz) ripple currents reduce design margining for AC‑biased applications.
• Long endurance at elevated temperature: 3000‑hour rating at 105°C provides predictable lifetime behavior under sustained thermal and electrical stress.
• Low dissipation factor: tanδ of 0.15 at 20°C/120 Hz supports lower internal heating and more stable impedance over time.
• Wide operating range: –40°C to 105°C enables use across varied ambient environments without specification loss.
• Robust snap‑in format: φ22 × 45 mm radial can with snap‑in termination offers secure mounting and straightforward PCB/assembly integration.
• Production readiness: Tray packing and mass production status simplify procurement and assembly planning.
