LQS2G471MELB45

The LQS2G471MELB45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LQS series, designed for high-voltage power applications. It delivers 470 µF at 400 V in a radial, snap‑in can package and targets general purpose power electronics where high ripple handling and long high‑temperature life are required.

Typical market segments include industrial drives and inverters, regenerative power circuits, and other equipment exposed to fluctuating voltages. The part combines high rated voltage, robust ripple current capability, and a specified 3000‑hour endurance at 105°C for reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 400 V for bulk energy storage and smoothing in high‑voltage power rails.
• High ripple current capability — Rated ripple currents of 1.68 A at 120 Hz and 2.402 A at 50 kHz to support high frequency and low frequency ripple conditions.
• High-temperature endurance — Specified lifetime of 3000 hours at 105°C under rated conditions, supporting sustained operation at elevated temperatures.
• Package and mounting — Snap‑in radial can package for secure board mounting in power assemblies; supplied in tray packing for mass production handling.
• Leakage and tolerance — Leakage current specified (1,300 µA) and capacitance tolerance of ±20% at 120 Hz, 20°C.
• Operating range — Rated for operation from –25°C to +105°C for use across a wide temperature span.
• Compliance — RoHS compliant.

Typical Applications

• Inverter and motor drives — Energy buffering and smoothing for AC servomotor inverters and general drive electronics that require high‑voltage capacitors.
• Regenerative power circuits — Suitable for high‑frequency regenerative voltage handling in systems with bidirectional energy flow.
• Voltage doubler/rectifier circuits — Use in rectifier and voltage‑doubling stages where high DC voltage and bulk capacitance are needed.
• Industrial power equipment — Applied in equipment operating in voltage‑fluctuating environments where long life at elevated temperature and reliable ripple handling are important.

Unique Advantages

• High-voltage capacitance in a compact snap‑in package: 470 µF at 400 V offers substantial energy storage while using a radial snap‑in can for secure mounting in power assemblies.
• Dual-frequency ripple performance: Rated ripple current values at both 120 Hz and 50 kHz address performance across low‑frequency and high‑frequency power systems.
• Designed for elevated-temperature operation: 3000 hours endurance at 105°C supports reliability in industrial thermal environments.
• Production-ready packaging: Tray packing and mass production availability simplify procurement and assembly for volume builds.
• Regulatory compliance: RoHS compliance supports use in regulated product lines.
