LGW2D222MELC45

The LGW2D222MELC45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGW series designed for general-purpose applications that demand high ripple current handling and long endurance at elevated temperature. It combines a 2.2 mF (2200 µF) capacitance with a 200 V rated voltage and polarized radial can packaging for robust power-electronic assemblies.

Key value propositions include high ripple capability, verified endurance under rated ripple at 105°C, and RoHS compliance for regulatory compatibility.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 200 V with ±20% tolerance, suitable for bulk energy storage and DC link applications where specified capacitance at rated voltage is required.
• High Ripple Current — Rated ripple current of 5.22 A at 120 Hz and 7.83 A at 50 kHz, enabling sustained AC ripple handling in demanding environments.
• 105°C Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, with performance limits defined for capacitance change, tan δ, and leakage current after endurance testing.
• Wide Operating Temperature Range — −40°C to +105°C rating (for 200 V models) to cover a broad set of environmental conditions.
• Snap-In Radial Can — Snap‑in terminal, radial can package for secure board mounting and mechanical stability in power assemblies.
• Polarized Design — Polarized construction appropriate for DC applications where correct polarity is maintained.
• RoHS Compliant — Complies with RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Compact Dimensions — Package size L: 4.5 × D: 3.5 cm for compact power designs where board space and volume are considerations.

Typical Applications

• Power Supply Filtering — Provides bulk capacitance and high ripple handling for smoothing and decoupling in general-purpose power supplies.
• DC Link / Energy Storage — Used where large capacitance at 200 V and sustained ripple endurance are needed to stabilize DC bus voltages.
• Industrial Power Equipment — Suited to general-purpose industrial applications that require long-term operation at elevated temperature and high ripple conditions.
• General-Purpose High‑Ripple Environments — Appropriate for assemblies that must tolerate continuous ripple currents and elevated ambient temperatures.

Unique Advantages

• Verified High-Temperature Ripple Endurance — Endurance specification of 3000 hours at 105°C under rated ripple current gives designers measurable lifetime performance under stress.
• Frequency-Resilient Ripple Performance — Ripple current ratings provided for both low (120 Hz) and high (50 kHz) frequencies to support a range of switching and line-frequency conditions.
• Secure Snap-In Mounting — Snap‑in terminal and radial can construction simplify assembly and improve mechanical retention for power modules and boards.
• Clear Electrical Specification Set — Explicit ratings for capacitance, voltage, tolerance, leakage, and tan δ enable straightforward engineering selection and verification.
• Regulatory Compatibility — RoHS compliance helps maintain regulatory conformity in product designs.
