LAK2G470MELA20ZB

The LAK2G470MELA20ZB is a Nichicon LAK series aluminum electrolytic capacitor in a snap‑in, radial can package designed for general‑purpose power applications. It delivers 47 µF capacitance at a 400 V rating with ±20% tolerance and is optimized for high‑temperature endurance and voltage‑fluctuating environments.

Built to withstand long‑term ripple stress, this part provides verified endurance at elevated temperature and includes series safety design elements to mitigate the effects of abnormal overvoltage conditions.

Key Features

• Capacitance & Voltage: 47 µF at 400 V rated — suitable for bulk energy storage and DC bus smoothing in medium‑voltage power stages.
• High‑Temperature Endurance: Rated for operation from −25°C to +105°C with a guaranteed life of 2000 hours at 105°C under specified ripple conditions.
• Ripple Current Performance: Low frequency ripple current 350 mA (120 Hz) and high frequency ripple current 402.5 mA (10 kHz) to support smoothing under AC and switching loads.
• Leakage & Dissipation: Measured leakage current 410 µA after rated voltage application; tangent of loss angle (tan δ) ≤ 0.20 at 20°C, 120 Hz for controlled dissipation factor.
• Safety Features: LAK series includes improved safety measures for abnormally excessive voltage, including a pressure relief vent to reduce hazardous outcomes under fault conditions.
• Package & Mounting: Snap‑in, radial can package (φ25 × 20 mm) for secure board mounting and mechanical stability; supplied in tray packing for efficient handling.
• Environmental Compliance: RoHS compliant construction.

Typical Applications

• Industrial power supplies: DC bus smoothing and bulk energy storage where 400 V ratings and high ripple endurance are required.
• Motor drives and inverters: Filtering and decoupling in systems subject to switching ripple and elevated operating temperatures.
• Voltage‑fluctuating equipment: Systems operating in environments with unstable supply voltages, leveraging the LAK series’ abnormal‑voltage safety features.

Unique Advantages

• Long life at elevated temperature: 2000 hours endurance at 105°C ensures predictable performance in hot environments, simplifying thermal design margins.
• High voltage capability: 400 V rating provides headroom for medium‑voltage DC applications without stacking or additional components.
• Robust ripple handling: Specified ripple current at both low and high frequencies supports performance across switching and line‑frequency conditions.
• Safety‑forward design: Series‑level measures for abnormal overvoltage and a pressure relief vent reduce the risk of hazardous failure modes.
• Board‑stable snap‑in package: Radial snap‑in can (φ25 × 20 mm) offers secure mechanical retention for through‑hole power assemblies.
• Regulatory compliance: RoHS conformity supports deployment in regulated markets and reduces material compliance risk.
