LGW2E182MELC50

The LGW2E182MELC50 is an aluminum electrolytic capacitor from Nichicon's LGW series, designed as a snap-in terminal type for high ripple current applications. It delivers 1.8 mF of capacitance at a 250 V rated voltage with polarized terminals and is intended for general-purpose power electronics requiring robust ripple handling and long-term endurance.

Key value propositions include high ripple-current capability across a wide frequency range, endurance under elevated temperature stress (3000 hours at 105°C with rated ripple), and RoHS compliance for environmental regulation alignment.

Key Features

• Capacitance and Voltage — 1.8 mF rated capacitance at 250 V provides substantial bulk energy storage for power filtering and smoothing.
• Snap-in Mounting — Snap-in terminal type and radial can package offer secure PCB mounting for power assemblies and chassis-mounted power modules.
• High Ripple Current & Endurance — Designed for high ripple environments; specified to withstand 3000 hours application of rated ripple current at 105°C.
• Ripple Current Performance — Measured ripple current: 4.05 A at 120 Hz and 6.075 A at 50 kHz, supporting both low- and high-frequency power applications.
• Operating Temperature Range — Rated for –40°C to +105°C operation (for the 200–250 V range), suitable for equipment operating in wide ambient conditions.
• Tolerance & Polarization — Capacitance tolerance of –20% to +20%; polarized electrolytic construction.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk filtering and smoothing in AC/DC and DC/DC power supplies where sustained ripple current handling is required.
• Industrial Power Modules — Energy storage and decoupling in industrial converters and power conditioning equipment operating up to 105°C.
• UPS and Inverter Systems — Bulk capacitance for short-term energy buffering and ripple mitigation in uninterruptible power and inverter applications.
• General Purpose Power Electronics — Systems requiring durable, high-capacitance, polarized capacitors for long-life ripple performance.

Unique Advantages

• Long High-Temperature Endurance: Specified to meet performance criteria after 3000 hours at 105°C with rated ripple current, supporting reliable long-term operation in hot environments.
• Validated Ripple Performance: Explicit ripple current ratings at 120 Hz and 50 kHz enable confident selection for both mains-frequency and high-frequency applications.
• High Capacitance at Elevated Voltage: 1.8 mF at 250 V offers significant bulk energy storage in a single component, simplifying BOM and board layout.
• Robust Mounting: Snap-in radial can design provides mechanically secure installation for power assemblies and improves serviceability.
• Regulatory Alignment: RoHS compliance supports environmental regulatory requirements for commercial and industrial products.
