LHX2W471MELC45

The LHX2W471MELC45 is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LHX series, offering 470 µF capacitance at a 450 V rating. Designed for general-purpose applications, it combines high-voltage capability with long-life performance and robust ripple handling.

With a compact 35 mm × 45 mm radial can and a snap-in mounting style, this part addresses designs that require reliable bulk capacitance, sustained operation at elevated temperatures, and production-ready packaging.

Key Features

• Electrical — 470 µF, 450 V Compact bulk capacitance rated 470 µF with a 450 V working voltage and ±20% capacitance tolerance (120 Hz, 20°C).
• Low loss and controlled leakage Specified tan δ ≤ 0.20 (120 Hz, 20°C) and leakage current approximately 1370 µA after voltage application, aiding stable performance over time.
• Ripple current capability Rated ripple current 1.91 A at 120 Hz (at 125°C) and approximately 2.73 A at high frequencies, supporting heavy AC stress on high-voltage rails.
• High-temperature long life Endurance rated for 5000 hours at 125°C, with an operating temperature range of −40°C to +125°C.
• Package and mounting Radial, can-style snap-in package (φ35 × 45 mm) for secure PCB mounting; supplied in tray packing and available in mass production quantities.
• RoHS compliant Constructed to meet RoHS requirements.

Typical Applications

• General-purpose power electronics Provides bulk capacitance and smoothing in high-voltage circuits where a 450 V rating and long-term stability are required.
• High-temperature installations Suited to equipment that must operate reliably across −40°C to +125°C with a 5000-hour life at elevated temperature.
• High-ripple environments Appropriate for designs that impose substantial ripple current on capacitors, benefiting from the rated 1.91 A (120 Hz) and ~2.73 A (high frequency) capability.

Unique Advantages

• High-voltage capability: 450 V rating supports high-voltage bus and power-conversion applications without additional series devices.
• Designed for elevated temperatures: 5000 hours at 125°C offers predictable endurance in hot operating environments.
• Superior ripple handling: Rated ripple currents reduce internal heating under AC stress, improving reliability in demanding circuits.
• Stable electrical characteristics: tan δ ≤ 0.20 and controlled leakage current support efficient, reliable performance over life.
• Board-ready packaging: Snap-in radial can (φ35 × 45 mm) with tray packing simplifies assembly and inventory management.
• Regulatory compliance: RoHS-compliant construction supports environmental requirements.
