LGU1C183MELZ

The LGU1C183MELZ from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, offering 18,000 µF capacitance at a 16 V rated voltage. Engineered for general‑purpose power applications, it combines high bulk capacitance with robust thermal and ripple endurance for demanding electronic systems.

Key value propositions include high ripple current capability, long life at elevated temperature, and a compact snap‑in radial can (φ22 × 45 mm) that supports efficient assembly and reliable power filtering in many equipment designs.

Key Features

• High Capacitance: 18,000 µF (18 mF) provides substantial bulk energy storage for smoothing, decoupling and DC link applications.
• Rated Voltage: 16 V rated voltage suitable for low‑voltage power rails and bus applications.
• Temperature & Endurance: Rated for operation from −40 °C to 105 °C with a guaranteed endurance of 3,000 hours at 105 °C under rated ripple conditions.
• Robust Ripple Performance: Low‑frequency ripple current 2.98 A at 120 Hz and high‑frequency ripple current 3.427 A at 50 kHz to handle AC ripple across a wide frequency range.
• Electrical Characteristics: Capacitance tolerance ±20% (measured at 120 Hz, 20 °C) and tangent of loss angle (tan δ) 0.50 at 20 °C, 120 Hz for this voltage class.
• Leakage: Leakage current specified at 1,600 µA (after standard initial conditions), supporting predictable bias behavior.
• Package & Mounting: Snap‑in radial can format (φ22 × 45 mm) for secure PCB mounting; supplied in tray packing for production handling.
• Compliance & Availability: RoHS‑compliant and listed as mass production status in the LGU series.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling on DC rails where large capacitance and reliable ripple handling are required.
• Energy storage for low‑voltage supplies — Provides bulk charge storage for transient load support and hold‑up in power systems.
• Power modules and converters — Suitable for use in converter DC links and filtering stages that demand sustained ripple endurance at elevated temperatures.

Unique Advantages

• Large capacitance in a compact can: 18,000 µF in a φ22 × 45 mm package reduces board space compared with multiple smaller capacitors.
• High ripple tolerance across frequencies: Specified ripple currents at 120 Hz and 50 kHz help ensure reliable performance across low and high ripple conditions.
• Long high‑temperature life: 3,000 hours at 105 °C under rated ripple current supports design longevity in hot operating environments.
• Manufacturing‑friendly mounting: Snap‑in radial can and tray packing simplify PCB assembly and handling for volume production.
• Predictable electrical behavior: Clear specifications for tan δ, leakage current and tolerance enable accurate design margining and simulation.
