LGU1K182MELA

The LGU1K182MELA is a snap‑in, radial can aluminum electrolytic capacitor from Nichicon's LGU series, specified for general purpose power applications. It provides 1.8 mF capacitance at a rated voltage of 80 V in a compact φ25 × 30 mm can and is supplied in tray packing for straightforward assembly.

Designed to operate across −40 °C to +105 °C and to withstand 3,000 hours of rated ripple current at 105 °C, this part delivers robust high‑temperature endurance and measurable ripple handling for bulk energy storage and filtering in elevated‑temperature environments.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 80 V provides bulk capacitance for smoothing and energy storage.
• Temperature Range & Endurance — Specified for −40 °C to +105 °C with 3,000 hours endurance at 105 °C under rated ripple current conditions.
• Ripple Current Performance — Low‑frequency ripple current of 1.86 A at 120 Hz and high‑frequency ripple current of 2.139 A at 50 kHz, supporting demanding ripple environments.
• Loss & Leakage Characteristics — Tangent of loss angle (tan δ) 0.20 (measured at 20 °C, 120 Hz) and leakage current 1130 µA, allowing predictable dissipation and leakage behavior.
• Mechanical & Mounting — Snap‑in radial can package (φ25 × 30 mm) for secure board mounting; height seated max 1.181 inch and Polarized construction.
• Compliance & Packaging — RoHS compliant and delivered in tray packing; product status: mass production.

Typical Applications

• General Purpose Power Filtering — Use for bulk smoothing and decoupling in power supply rails where 1.8 mF at 80 V and robust ripple capability are required.
• High‑Temperature Power Systems — Suitable for applications that operate up to 105 °C and require long endurance (3,000 hours) under rated ripple conditions.
• Energy Storage and Hold‑Up — Provides compact bulk capacitance for short‑term energy hold‑up or transient buffering in radial, snap‑in form factors.

Unique Advantages

• Measured high‑temperature endurance: 3,000 hours at 105 °C under rated ripple current—designed for long service life in elevated‑temperature environments.
• High ripple handling: Specified ripple currents of 1.86 A (120 Hz) and 2.139 A (50 kHz) enable reliable performance across low and high frequency ripple conditions.
• Predictable dissipation and leakage: tan δ = 0.20 (20 °C, 120 Hz) and leakage current 1130 µA provide clear thermal and leakage expectations for design margining.
• Space‑efficient snap‑in package: φ25 × 30 mm radial can with snap‑in terminals simplifies board mounting for power assemblies.
• Production readiness and compliance: RoHS compliant and in mass production with tray packing for volume assembly and supply chain consistency.
