LGW2D122MELB40

The LGW2D122MELB40 is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose power applications. It combines a 1.2 mF capacitance with a 200 V rating in a radial, snap‑in can package.

Engineered for demanding ripple environments, this part delivers high ripple current capability and long endurance at elevated temperatures, while complying with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance and Voltage: 1.2 mF capacitance with a rated voltage of 200 V for bulk energy storage and smoothing in medium‑voltage systems.
• High Ripple Current Performance: Rated ripple current of 4.2 A at 120 Hz and 6.3 A at 50 kHz, supporting applications with significant AC ripple components.
• 105°C Endurance: Withstands 3000 hours of rated ripple current at 105°C, providing predictable behavior under sustained elevated temperature and ripple stress.
• Wide Operating Range: Operating temperature range from −40°C to +105°C to accommodate a broad set of environmental conditions.
• Mounting and Package: Snap‑in terminal, radial can (snap‑in) package with compact dimensions (L: 4 × D: 3 cm) for vertical board mounting.
• Polarized Design and Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% for design margin planning.
• Environmental Compliance: Compliant with RoHS (2011/65/EU,(EU)2015/863).

Typical Applications

• General‑purpose power supplies: Bulk smoothing and ripple handling where a 200 V, 1.2 mF capacitor with high ripple capability is required.
• Industrial power electronics: Use in equipment that requires sustained ripple filtering at elevated temperatures up to 105°C.
• High‑ripple converter stages: Energy storage and decoupling in converter or inrush applications that present significant AC ripple currents.

Unique Advantages

• Long high‑temperature endurance: Rated to withstand 3000 hours of rated ripple current at 105°C, enabling reliable performance in thermally challenging installations.
• Measured high ripple capability: Specified ripple current values at both low and high frequencies (4.2 A at 120 Hz, 6.3 A at 50 kHz) support mixed‑frequency noise environments.
• Snap‑in radial can: Snap‑in terminal simplifies vertical board mounting and mechanical retention for power assemblies.
• Wide operating temperature range: −40°C to +105°C rating supports a wide spectrum of commercial and industrial environments.
• RoHS compliant: Meets current RoHS requirements for environmental and regulatory conformity.
