LGX2G151MELZ35

The LGX2G151MELZ35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series, designed for long‑life power applications. It provides 150 µF capacitance at a 400 V rating in a compact radial can snap‑in package.

Engineered for rectifier circuits in general inverters and switching power supplies, this part delivers extended endurance—meeting 5000 hours of operation with rated ripple current at 105°C—and is RoHS compliant.

Key Features

• Capacitance and Tolerance — 150 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20°C.
• High Voltage Rating — 400 V rated voltage for use in higher‑voltage power rails and rectifier stages.
• Long Life at Elevated Temperature — Endurance specified as 5000 hours when subjected to rated ripple current at 105°C, supporting sustained high‑temperature operation.
• Ripple Current Capability — Specified ripple handling of 860 mA at 120 Hz and 1.23 A at 50 kHz, suitable for smoothing and filtering in power conversion circuits.
• Operating Temperature Range — Rated for −25°C to +105°C to cover a broad range of industrial ambient conditions.
• Snap‑in Radial Can Package — Snap‑in mounting for secure PCB retention in power assemblies; package dimensions approximately L: 3.5 × D: 2.2 cm.
• Leakage Current Specification — Per series datasheet: I ≤ 3√(C·V) µA after 5 minutes application of rated voltage at 20°C.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk and output filtering where sustained ripple handling and high voltage are required.
• Inverter Rectifier Circuits — DC link and smoothing capacitors for general inverter designs.
• General Purpose Power Electronics — Industrial power conversion and control systems requiring long life at elevated temperatures.

Unique Advantages

• Long‑life performance: 5000‑hour endurance at 105°C under rated ripple current supports reliability in continuous high‑temperature use.
• High voltage capability: 400 V rating enables use on higher DC rail voltages without series stacking.
• Robust ripple handling: Specified ripple currents at both low and high frequencies reduce the need for oversized solutions.
• Secure snap‑in mounting: Snap‑in radial can eases assembly and provides firm retention for power PCB layouts.
• Regulatory compliance: RoHS conformity simplifies selection for environmentally regulated designs.
