LGN2W471MELC45

The LGN2W471MELC45 is a snap‑in terminal aluminum electrolytic capacitor rated at 470 µF and 450 V. It is a smaller‑sized member of Nichicon’s LGN series designed for general‑purpose applications that require high‑voltage capability and sustained performance at elevated temperatures.

Engineered for robust high‑temperature endurance, this capacitor withstands rated ripple current for 3000 hours at 105°C and is RoHS compliant, offering a compact, reliable solution where long life and high voltage are required.

Key Features

• Capacitance & Voltage — 470 µF capacitance with a 450 V rated voltage, suitable for high‑voltage, high‑capacitance requirements.
• Temperature & Endurance — Rated operating temperature range of −25°C to +105°C (for 350–600 V parts) and specified endurance of 3000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 1.78 A at 120 Hz and 2.545 A at 100 kHz, supporting applications with significant AC ripple stress.
• Package & Mounting — Snap‑in terminal, radial can (snap‑in) package for secure PCB mounting and easy assembly.
• Size Efficiency — One rank smaller case size than the LGU series, providing comparable performance in a reduced footprint.
• Tolerance & Polarity — Capacitance tolerance of −20% to +20% and polarized construction.
• Leakage & Loss Characteristics — Series electrical characteristics include controlled leakage current (I ≤ 3/√C µA after 5 minutes at 20°C) and specified tan δ limits per rated voltage ranges.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Electronics — Suited for circuits requiring a 450 V, high‑capacitance component with sustained performance at elevated temperatures.
• Industrial Equipment — Applicable where long‑life, high‑voltage capacitors with secure snap‑in mounting are required.
• High‑Temperature Environments — Designed for systems operating up to 105°C with a 3000‑hour ripple endurance specification.

Unique Advantages

• High‑Voltage, High‑Capacitance Combination: 470 µF at 450 V provides substantial energy storage in a single device, reducing the need for parallel components.
• Long High‑Temperature Endurance: Rated to withstand rated ripple current for 3000 hours at 105°C, delivering predictable lifetime under thermal stress.
• Compact Footprint: One rank smaller case than the LGU series helps save board space without sacrificing key electrical performance.
• Robust Ripple Handling: Specified ripple current at both low (120 Hz) and high (100 kHz) frequencies supports a range of switching and AC conditions.
• Secure Snap‑in Mounting: Radial, snap‑in can package enables reliable mechanical retention and straightforward assembly.
• Regulatory Compliance: RoHS compliant for use in equipment requiring restricted substance conformity.
