LGU1C183MELA

The LGU1C183MELA is a snap‑in terminal aluminum electrolytic capacitor engineered for general‑purpose power applications that require high capacitance and long endurance. It delivers 18,000 µF at a 16 V rating in a radial, can‑style snap‑in package sized φ25 × 40 mm.

Designed for sustained operation up to 105°C, this component targets applications where bulk energy storage, smoothing and power conditioning are required while meeting RoHS environmental requirements.

Key Features

• High Capacitance: 18,000 µF (18 mF) nominal capacitance provides substantial bulk energy storage for power rails and filtering.
• Rated Voltage and Tolerance: 16 V rated voltage with ±20% capacitance tolerance (measured at 120 Hz, 20°C) for predictable performance in DC bias applications.
• Snap‑in Radial Package: Radial, can‑style snap‑in terminals for secure board mounting and reliable mechanical retention.
• 105°C Endurance: Qualified for 3,000 hours at 105°C with rated ripple current applied, maintaining capacitance within ±20% and leakage current within initial specified limits.
• Operating Temperature Range: –40°C to +105°C for wide ambient tolerance across general‑purpose installations.
• Ripple Current Capability: Rated ripple current of 3.16 A at 120 Hz and 3.634 A at 50 kHz; frequency coefficients for ripple current are provided for 16–100 V group (e.g., 0.88 at 50 Hz, 1.00 at 120 Hz, 1.15 at ≥10 kHz).
• Electrical Loss (tan δ): Maximum tan δ of 0.50 at 120 Hz, 20°C for the 16 V rating, supporting predictable ESR behavior in AC conditions.
• Environmental Compliance & Packaging: RoHS‑compliant with tray packing suitable for mass production supply chains.

Typical Applications

• General purpose power filtering: Bulk capacitance and 16 V rating suit smoothing and decoupling tasks where large energy reserve is required.
• Power conditioning and hold‑up: High capacitance combined with rated ripple current and 105°C endurance supports sustained ripple handling and energy buffering.
• Industrial and commercial electronics: Wide operating temperature range (–40°C to +105°C) and long life make it appropriate for general‑purpose applications in production environments.

Unique Advantages

• Large capacitance in a compact can: 18,000 µF in a φ25 × 40 mm package offers significant energy storage while minimizing board footprint.
• Long high‑temperature endurance: Specified 3,000 hours at 105°C under rated ripple current for predictable long‑term behavior in elevated temperatures.
• Reliable ripple performance: Explicit ripple current ratings at 120 Hz and 50 kHz, plus frequency coefficients, enable designers to match the part to real‑world operating frequencies.
• Robust mounting: Snap‑in radial can provides mechanical retention and quick insertion for high‑volume assembly.
• Regulatory compliance: RoHS compliance supports integration into environmentally conscious product lines and supply chains.
