LGU2Z681MELA

The LGU2Z681MELA is a Nichicon snap-in terminal aluminum electrolytic capacitor providing 680 µF at 180 V in a compact φ25 × 35 mm can. It is a 105°C standard snap-in type designed for general-purpose applications where high ripple handling and long endurance are required.

Key value propositions include high ripple-current capability across low and high frequencies, defined dissipation factor and leakage specifications, and a 3000-hour endurance rating at 105°C for reliable long-term operation in power circuits.

Key Features

• Capacitance & Rated Voltage — 680 µF nominal capacitance rated for 180 V DC, suitable for bulk energy storage and filtering in general-purpose power circuits.
• Tolerance & Polarization — ±20% capacitance tolerance at 120 Hz, 20°C and polarized construction for correct DC applications.
• Low Loss (tan δ) — tan δ 0.15 maximum measured at 20°C and 120 Hz (per series specification for this voltage range), supporting predictable AC losses in design.
• High Ripple Current Capability — 1.78 A at 120 Hz (low frequency) and 2.67 A at 50 kHz (high frequency), enabling effective ripple handling across a broad frequency range.
• Leakage Current — 1040 µA specified leakage current after rated voltage application, providing quantifiable self-discharge characteristics.
• Endurance & Temperature Range — Rated for 3000 hours at 105°C with D.C. bias plus rated ripple current; operating temperature range −40°C to +105°C.
• Package & Mounting — Radial, snap-in can package (φ25 × 35 mm footprint) supplied in tray packing for production assembly.
• Regulatory Status — RoHS compliant.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling in general-purpose power supplies where 680 µF at 180 V is required.
• Energy Storage — Local energy reservoir for circuits that need stable capacitance and specified ripple endurance at elevated temperatures.
• Industrial Control Electronics — General-purpose use in industrial power modules and assemblies requiring high ripple-current capability and 105°C endurance.

Unique Advantages

• High Ripple Handling: Specified 1.78 A (120 Hz) and 2.67 A (50 kHz) ripple currents allow designers to manage AC stress across common power and switching frequencies.
• Long High‑Temperature Endurance: With a 3000-hour rating at 105°C under rated ripple and bias, the capacitor supports extended service life in hot operating environments.
• Predictable Loss and Leakage: Defined tan δ and leakage current values (0.15 tan δ; 1040 µA leakage) give engineers measurable parameters for thermal and discharge budgeting.
• Production‑Ready Packaging: Snap-in radial can in tray packing supports efficient PCB assembly and high-volume manufacturing flows.
• RoHS Compliant: Meets RoHS requirements for environmentally constrained production designs.
