LGJ2Z151MELZ15

The LGJ2Z151MELZ15 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGJ series designed for general‑purpose power electronics. It combines a 150 µF capacitance with a 400 V rated voltage, a compact snap‑in can package, and performance characteristics targeted at ripple filtering and energy storage in medium‑voltage applications.

Engineered for sustained operation up to 105°C, this part offers a balance of high‑frequency ripple capability and low leakage for reliable performance in assemblies where long life and thermal endurance matter.

Key Features

• Capacitance and Tolerance — 150 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 400 V rated voltage suitable for medium‑voltage power circuits.
• Snap‑In Terminal Package — Radial, can-style snap‑in mounting for secure chassis insertion and mechanical stability.
• High‑Frequency Ripple Performance — Rated ripple current of 900 mA at 50 kHz for demanding HF filtering tasks; 600 mA at 120 Hz for low‑frequency ripple.
• Low Leakage — Specified leakage current of 0.73 µA, supporting low standby losses and stable DC performance.
• High‑Temperature Endurance — 2000 hours life at 105°C for extended reliability in thermally stressed environments.
• Operating Temperature Range — −40°C to +105°C for broad environmental applicability.
• Compact Low‑Profile Size — Cylindrical can, specified size φ30 × 20 mm, suitable for space‑constrained power modules.
• Production and Packaging — Tray packing and mass production status for repeatable procurement and assembly.

Typical Applications

• Power Supply Filtering — Used for bulk smoothing and ripple reduction where 400 V DC bus voltages are present and high ripple handling is required.
• DC Link and Energy Storage — Serves as an intermediate energy buffer in converters and inverters requiring sustained operation at elevated temperatures.
• Industrial Electronics — Suitable for general‑purpose industrial control equipment that demands long life at 105°C and reliable high‑frequency performance.
