The LGX2H151MELB30 is a Nichicon LGX-series snap‑in aluminum electrolytic capacitor rated at 150 µF and 500 V. It is a radial can, snap‑in terminal type designed for general-purpose power applications, with a smaller-sized package measuring 30 × 30 mm.

Engineered for high-voltage power circuits such as rectifier stages in inverters and switching power supplies, this capacitor offers long-life assurance at elevated temperature and is RoHS compliant.

Key Features

• Capacitance and Voltage — 150 µF nominal capacitance with a 500 V rated voltage and ±20% tolerance for bulk energy storage in high-voltage DC circuits.
• Long-life Endurance — Designed for 5000 hours of endurance at 105°C under rated ripple conditions, supporting reliable operation in thermal-stressed power environments.
• Temperature Range — Operating temperature from −25°C to +105°C, allowing use across a wide set of industrial ambient conditions.
• High Ripple Capability — Rated ripple current of 910 mA at 120 Hz and 1.301 A at 50 kHz to handle AC components present in rectifier and smoothing applications.
• Low-Temperature Performance — Specified impedance stability with Z(−25°C)/Z(+20°C) up to 8 for the 400–500 V range, supporting low-temperature startup performance.
• Leakage and Loss Characteristics — Leakage current limited by I ≤ 3√CV (μA) after standard preconditioning; tangent of loss angle (tan δ) up to 0.20 for 450–500 V at 120 Hz, 20°C.
• Package and Mounting — Snap‑in radial can package (φ30 × 30 mm) for secure PCB mounting in power assemblies.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Stages — Bulk smoothing and energy storage in rectifier circuits for general inverters.
• Switching Power Supplies — Output filtering and ripple smoothing where high-voltage DC capacitance and long life at elevated temperature are required.
• General Power Electronics — High-voltage DC filtering and decoupling in industrial and commercial power systems.

Unique Advantages

• Long-Term Thermal Reliability: 5000 hours endurance at 105°C provides predictable life performance for high-temperature power designs.
• High-Voltage Capability: 500 V rating enables use in higher-voltage DC buses and rectifier outputs without series stacking.
• Compact Snap‑in Form Factor: φ30 × 30 mm radial can with snap‑in terminals offers a space-efficient, mechanically robust mounting for power boards.
• Measured Ripple Performance: Specified ripple currents at both low (120 Hz) and high (50 kHz) frequencies help designers size capacitors to meet transient and steady-state ripple demands.
• Verified Low-Temperature Behavior: Impedance and loss-angle specifications at −25°C support reliable startup and cold-condition performance.
• RoHS Compliance: Meets RoHS directive requirements for restricted substances.
