LGY1C183MELA40

The LGY1C183MELA40 is a snap‑in terminal aluminum electrolytic capacitor designed for long‑life power applications. It delivers 18,000 µF capacitance at 16 V in a radial can snap‑in package optimized for power filtering and bulk energy storage.

Engineered for industrial use, this part targets general‑purpose power supplies and ballast applications that require dependable ripple handling and extended endurance at elevated temperatures.

Key Features

• High Capacitance: 18,000 µF (±20%) provides substantial bulk energy storage for smoothing and hold‑up in power systems.
• Rated Voltage: 16 V DC—suitable for low‑voltage power rails and intermediate bus decoupling.
• Long‑Life Endurance: Qualified for 5,000 hours at 105°C when subjected to rated ripple conditions, supporting extended service in high‑temperature environments.
• Robust Ripple Performance: Rated ripple current of 3.0 A at 120 Hz and 3.45 A at 50 kHz to handle both low and high frequency ripple components.
• Low Leakage & Loss: Leakage current specified at 1,600 µA and tan δ of 0.50 (16 V, 120 Hz) for predictable DC performance and controlled dissipation.
• Wide Operating Temperature: −40°C to +105°C operating range for use across demanding environmental conditions.
• Snap‑in Radial Can: Snap‑in mounting type and radial can package simplify board installation and mechanical retention for through‑hole assembly.
• RoHS Compliant & Production Ready: RoHS status compliant with tray packing and mass production availability.

Typical Applications

• Industrial Power Supplies: Bulk filtering and hold‑up capacitors where high ripple currents and long life at elevated temperatures are required.
• Ballast Applications: Energy storage and smoothing in ballast circuits as identified for the LGY series.
• General‑Purpose Power Filtering: DC bus decoupling and smoothing in power conversion, inverters, and auxiliary power modules.

Unique Advantages

• Extended High‑Temperature Reliability: 5,000‑hour endurance at 105°C reduces frequency of replacement in hot‑running power designs.
• High Ripple Capability: 3.0 A (120 Hz) and 3.45 A (50 kHz) ripple ratings permit smaller capacitor arrays and improved thermal margin under ripple stress.
• Large Energy Density: 18,000 µF at 16 V delivers significant charge storage in a compact φ25 × 40 mm package for space‑constrained boards.
• Predictable Leakage and Dissipation: Specified leakage current and tan δ enable accurate thermal and standby current budgeting in system designs.
• Board‑Friendly Mounting: Snap‑in terminals provide secure mechanical retention for through‑hole assembly and automated placement from tray packing.
• Regulatory Compliance: RoHS compliance supports use in designs targeting global environmental requirements.
