LAK2G330MELZ20ZB

The LAK2G330MELZ20ZB is a Nichicon LAK series snap‑in aluminum electrolytic capacitor rated 400 V with 33 µF capacitance. Designed for general‑purpose power electronics, it delivers high‑voltage filtering and smoothing capability in a compact radial, can‑type snap‑in package.

Key value comes from its 105°C endurance rating with 2000 hours of life under rated ripple conditions, built‑in safety features for abnormal overvoltage events, and RoHS compliance—making it suitable for high‑voltage power supplies and industrial equipment where thermal and ripple robustness are required.

Key Features

• Electrical rating — 33 µF nominal capacitance at 400 V DC with ±20% tolerance (120 Hz, 20°C), providing stable high‑voltage bulk capacitance.
• Ripple performance — Rated ripple current of 220 mA at 120 Hz and 253 mA at 10 kHz, enabling effective smoothing of AC ripple across a range of frequencies.
• Leakage and loss — Low leakage current (approximately 340 µA) and a maximum tan δ of 0.20 at 120 Hz, 20°C, for predictable leakage and dissipation characteristics.
• Thermal endurance — Rated operating range −25°C to +105°C with a 2000‑hour endurance specification at 105°C under D.C. bias plus rated ripple current (capacitance change within ±20%, tan δ ≤200% of initial, leakage ≤ initial).
• Safety features — Improved safety design for abnormally excessive voltage and a pressure relief vent that operates without creating dangerous conditions such as flames or fragmentation.
• Package and mounting — Radial, snap‑in can package with compact dimensions (approximately 22 × 20 mm) and tray packing for production handling.
• Regulatory status — RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and decoupling in high‑voltage DC and AC‑to‑DC power stages where 400 V rated capacitance is required.
• Industrial power electronics — Filtering and energy buffering in industrial controllers and power conversion equipment operating at elevated temperatures.
• High‑voltage DC link — Use in DC link and intermediate circuits where endurance at 105°C and rated ripple handling are necessary.

Unique Advantages

• High-voltage capability: 400 V rating provides margin for high‑voltage power rails while keeping component count low.
• Designed for sustained ripple: Specified ripple currents at both low and high frequencies support stable operation in a variety of switching and line‑frequency environments.
• Thermal reliability: 2000 hours at 105°C endurance ensures predictable life and performance under elevated temperature and bias conditions.
• Safety‑focused design: Pressure relief vent and improved overvoltage safety features reduce risk during abnormal voltage events.
• Production ready: Tray packing and mass‑production status simplify procurement and assembly for volume production runs.
