LAQ2G471MELC45ZB

The LAQ2G471MELC45ZB is a snap‑in, aluminum electrolytic capacitor from Nichicon's LAQ series. It delivers 470 µF nominal capacitance at a 400 V rating in a compact radial snap‑in can (φ35 × 45 mm).

Designed for general‑purpose power applications requiring high voltage bulk capacitance, the device combines a 105 °C permissible abnormal voltage design, long endurance (2000 h at 105 °C), controlled dissipation (tanδ ≤ 0.20 at 20 °C/120 Hz), and defined ripple and leakage characteristics for reliable performance in elevated temperature environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance rated for 400 V, with ±20% tolerance at 20 °C/120 Hz.
• High‑temperature Endurance — Qualified for 2000 hours at 105 °C under DC bias plus rated ripple current; capacitance and leakage remain within specified limits after endurance testing.
• Low Dissipation Factor — tanδ ≤ 0.20 (120 Hz at 20 °C) for predictable loss performance in filter and bulk applications.
• Ripple Current Capability — 1.87 A (120 Hz) low‑frequency ripple and 2.151 A (10 kHz) high‑frequency ripple ratings to support AC ripple handling and smoothing duties.
• Leakage Current — Specified leakage current of 1300 µA measured after rated voltage application, enabling predictable bias characteristics.
• Snap‑in Radial Can Package — Snap‑in terminal type in a radial, can‑snap‑in package for secure board mounting; tray packing for mass production handling.
• Safety Vent — Pressure relief vent designed to operate without creating dangerous conditions such as flames or dispersion of case fragments.

Typical Applications

• General Purpose Power — Bulk energy storage and smoothing where 470 µF at 400 V and elevated temperature endurance are required.
• Industrial Electronics — Filtering and reservoir functions in high‑voltage industrial power circuits needing long life at up to 105 °C.
• Power Conversion — DC bus and intermediate circuit stabilization where defined ripple handling (120 Hz and 10 kHz ratings) is important.

Unique Advantages

• High‑voltage capability: 400 V rating provides the margin needed for high‑voltage bulk and filtering applications.
• Extended high‑temperature life: 2000‑hour endurance at 105 °C supports long operational life in thermally demanding installations.
• Predictable ripple performance: Specified ripple currents at both low and high frequencies allow designers to size capacitors with confidence for AC ripple loads.
• Controlled loss and leakage: Low tanδ (≤0.20) and specified leakage current enable stable thermal and bias behavior in circuits.
• Robust mechanical mounting: Snap‑in radial can simplifies secure PCB installation and mass‑production assembly with tray packing.
• Safety‑oriented design: Pressure relief vent reduces the risk of hazardous failure modes under abnormal conditions.
