LAQ2G471MELC45

The LAQ2G471MELC45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, offering 470 µF capacitance at a 400 V rating. Designed for general purpose applications, this radial can‑style capacitor delivers high voltage capability, defined ripple handling and long endurance for equipment operating in voltage‑fluctuating environments.

Key value propositions include a snap‑in mounting for robust board retention, explicit ripple current ratings at both low and high frequencies, and a 2000‑hour endurance rating at 105°C for sustained performance under elevated temperature stress.

Key Features

• Capacitance & Tolerance: 470 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C).
• High Voltage Rating: Rated for 400 V operation, providing extended voltage capability within the LAQ series.
• Ripple Current Performance: Rated ripple current of 1.87 A at 120 Hz and 2.151 A at 10 kHz, specified for low‑ and high‑frequency ripple handling.
• Endurance at Elevated Temperature: 2000 hours lifetime specified at 105°C with D.C. bias plus rated ripple current applied.
• Leakage Current: Specified leakage current of 1300 µA (measured after rated voltage application at 20°C).
• Package & Mounting: Snap‑in radial can (φ35 × 45 mm length) for secure PCB mounting; tray packing suitable for mass production handling.
• Temperature Range: Operates from −25°C to +105°C as specified for the LAQ series.
• Safety Features: Series design includes a pressure relief vent to mitigate abnormal overvoltage conditions.
• Regulatory Note: The LAQ series is stated as compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Systems: Suitable where a high‑voltage, electrolytic smoothing or energy storage capacitor is required in general purpose equipment.
• Equipment in Voltage‑Fluctuating Areas: Intended for systems subject to fluctuating supply voltages, leveraging the series' improved safety features and extended voltage range.
• High‑Voltage Modules and Subsystems: Use where 400 V rated capacitance and reliable ripple handling at multiple frequencies are needed.

Unique Advantages

• 400 V Capability: Enables use in higher‑voltage circuits without series stacking, simplifying design considerations for 400 V systems.
• Dual‑Frequency Ripple Ratings: Explicit ripple current specifications at 120 Hz and 10 kHz allow designers to size capacitors based on real operating ripple conditions.
• Long High‑Temperature Endurance: 2000 hours at 105°C demonstrates stability under prolonged thermal stress, supporting durable system operation.
• Snap‑in Radial Can Package: Secure mechanical retention and straightforward insertion for production environments, supplied in tray packing for mass production.
• Leakage and Safety Controls: Specified leakage current and a pressure relief vent help maintain predictable failure modes and safer operation under abnormal conditions.
• Series Compliance: LAQ series RoHS compliance supports designs targeting current environmental directives.
