LGX2D182MELC45

The LGX2D182MELC45 is a Nichicon LGX-series aluminum electrolytic capacitor with a snap-in terminal package designed for general-purpose power applications. It provides 1.8 mF (1,800 μF) capacitance at a 200 V rating in a compact radial can with snap-in terminals.

Engineered for elevated-temperature operation and extended reliability, this part supports continuous operation up to 105°C with a guaranteed lifetime of 5,000 hours at 105°C under rated ripple current. Typical use cases include rectifier circuits in inverters and switching power supplies where high capacitance, high-voltage smoothing and long endurance are required.

Key Features

• Capacitance & Voltage — 1.8 mF (1,800 μF) rated at 200 V for high-voltage DC smoothing and energy storage in power circuits.
• High-Temperature Endurance — Rated for operation from −25°C to +105°C and specified for 5,000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Specified ripple handling of 3.28 A at 120 Hz and 4.92 A at 50 kHz, supporting both low- and high-frequency ripple conditions.
• Snap-In, Radial Can Package — Snap-in terminal mounting for secure board attachment and ease of installation in power assemblies.
• Tolerance & Polarization — Polarized capacitor with capacitance tolerance of −20% to +20% for predictable filtering performance.
• Smaller-Sized Design — Compact dimensions (L: 4.5 × D: 3.5 cm) delivering high capacitance in a reduced footprint for space-constrained power designs.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Power Conversion — Used in rectifier circuits for general inverters and switching power supplies to smooth DC rails and reduce ripple.
• Industrial Power Supplies — Provides high-voltage bulk capacitance and long-life performance for industrial SMPS and DC bus filtering.
• General-Purpose Filtering — Suitable for smoothing and decoupling in a range of high-voltage, general-purpose power electronics applications.

Unique Advantages

• Long-Life Specification — Rated for 5,000 hours at 105°C under rated ripple current, enabling predictable lifetime planning in high-temperature environments.
• Dual-Frequency Ripple Performance — Clear ripple current ratings at both 120 Hz and 50 kHz allow selection for designs that experience varied ripple spectra.
• Secure Snap-In Mounting — Snap-in terminals simplify assembly and provide reliable mechanical retention for power boards and assemblies.
• High Capacitance in Compact Package — 1.8 mF in a smaller-sized radial can helps reduce board area without sacrificing bulk capacitance.
• Designed for Power Circuitry — Specifically suited for rectifier circuits in inverters and switching power supplies per the LGX series design intent.
• Regulatory Compliance — RoHS compliance supports environmental and regulatory requirements.
