LGX2D391MELZ30

The LGX2D391MELZ30 is a Nichicon LGX-series snap-in aluminum electrolytic capacitor designed for power-electronics applications. It combines a 390 µF capacitance with a 200 V rated voltage in a compact radial can snap-in package.

Engineered for long-life operation, this capacitor is specified to withstand rated ripple current for 5000 hours at 105°C and is suited for rectifier circuits in general inverters and switching power supplies. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance at a rated voltage of 200 V, with tolerance of −20% to +20%.
• Long-life at High Temperature — Endurance rating of 5000 hours at 105°C under DC bias plus rated ripple current, supporting extended operation in thermal stress environments.
• High ripple current capability — Rated ripple current of 1.38 A at 120 Hz and 2.07 A at 50 kHz, supporting bulk filtering and smoothing in power circuits.
• Operating temperature range — Specified for −25°C to +105°C operation to cover common industrial and power-electronics thermal envelopes.
• Snap-in radial can package — Snap-in mounting for secure fast assembly; physical size approximately 22 × 30 mm (D × L) with a seated height of 1.181 inch (30.0 mm).
• Leakage and loss characteristics — Conforms to Nichicon LGX-series leakage current and tan δ specifications as listed for the series.
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications
