LGU1K182MELB

The LGU1K182MELB is a snap‑in aluminum electrolytic capacitor from Nichicon's LGU series, offering 1800 µF capacitance at an 80 V rating. It is designed for general‑purpose applications that require high ripple current handling and prolonged endurance at elevated temperatures.

Key value propositions include robust ripple performance (1.81 A at 120 Hz and 2.082 A at 100 kHz), a wide operating temperature range of −40 °C to +105 °C, and a 3000‑hour endurance rating at 105 °C for reliable long‑term operation.

Key Features

• Capacitance and Tolerance — 1800 µF nominal capacitance with ±20% tolerance (−20% to +20%) at 120 Hz, 20 °C.
• Voltage Rating — Rated for 80 V DC for use in higher‑voltage general‑purpose power circuits.
• High Ripple Current Capability — Low‑frequency ripple current of 1.81 A at 120 Hz and high‑frequency ripple current of 2.082 A at 100 kHz, supporting demanding ripple environments.
• Endurance at Elevated Temperature — Qualified to withstand rated ripple current for 3000 hours at 105 °C, meeting the LGU series endurance specification.
• Temperature Range — Operates from −40 °C to +105 °C to cover a wide range of environmental conditions.
• Low Losses — Tangent of loss angle (tan δ) of 0.20 measured at 20 °C, 120 Hz for stable AC performance.
• Leakage Current — Specified leakage current of 1130 µA after voltage application (20 °C, initial measurement condition).
• Snap‑In Package — Radial can with snap‑in terminals (φ30 × 25 mm) for secure board mounting and tray packing for production handling.
• RoHS Compliant — Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Industrial Power Electronics — Bulk smoothing and filtering where an 80 V rating, high ripple current capability, and 105 °C endurance are required.
• Commercial Power Supplies — General‑purpose energy storage and decoupling in higher‑voltage supply rails leveraging the 1800 µF capacitance and snap‑in mounting.
• High‑Temperature Environments — Systems that must maintain capacitance and leakage limits after extended operation at elevated temperature, supported by the 3000‑hour endurance at 105 °C.

Unique Advantages

• High Endurance at Elevated Temperature: The LGU1K182MELB is specified for 3000 hours at 105 °C under rated ripple, reducing maintenance and replacement frequency in hot environments.
• Balanced Ripple Performance: Defined ripple current specs at 120 Hz and 100 kHz provide predictable behavior across common power‑system frequencies.
• Compact Snap‑In Form Factor: φ30 × 25 mm snap‑in can offers a compact footprint with robust mechanical retention for PCB assemblies.
• Clear Electrical Limits: Specified tan δ (0.20) and leakage current (1130 µA) enable designers to budget losses and standby currents precisely.
• Production‑Ready Packaging: Tray packing supports automated placement and handling in volume manufacturing.
• Regulatory Compliance: RoHS compliance simplifies environmental compliance management for product designs.
