LGU2F471MELA

The LGU2F471MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor designed for general-purpose high-voltage applications. This radial can (φ25×50 mm) delivers 470 µF at a 315 V rated voltage with a 105 °C temperature rating and a 3000‑hour endurance at 105 °C.

Its combination of high voltage, substantial capacitance and specified ripple handling makes it suitable where bulk energy storage, smoothing and high‑voltage filtering are required in industrial and power electronics designs.

Key Features

• Electrical Performance 470 µF capacitance at 315 V with ±20% tolerance (at 120 Hz, 20 °C); leakage current specified at 1150 µA (measured after 5 minutes at rated voltage).
• High Voltage & Ripple Capability Rated for 315 V DC; rated ripple current 1.700 A at 120 Hz (low frequency) and 2.431 A at high frequency (100 kHz) for effective ripple handling.
• Thermal & Endurance 105 °C maximum operating temperature and endurance specified: 3000 hours at 105 °C under rated DC bias plus rated ripple current, with capacitance change within ±20% after the test.
• Package & Mounting Snap‑in terminal, radial can package (φ25 × 50 mm) for secure board retention and mechanical stability in through‑hole assemblies.
• Low‑Temperature Behavior Rated for operation down to −25 °C for 315–450 V parts in the LGU series; impedance characteristics follow series low‑temperature stability guidelines.
• Regulatory Compliance RoHS compliant per the series specification.

Typical Applications

• High‑Voltage Power Supplies — Bulk energy storage and smoothing where a 315 V rated capacitor and 470 µF capacitance are required for stable DC rails.
• Industrial Power Electronics — Filtering and ripple suppression in inverters, converters and industrial controllers that operate at elevated voltages and temperatures.
• Energy Storage and Smoothing — DC link and hold‑up applications that need extended endurance (3000 h at 105 °C) under DC bias and ripple current.

Unique Advantages

• Rated for High Voltage — 315 V rating enables use in higher‑voltage systems without requiring multiple lower‑voltage parts in series.
• High Ripple Endurance — Specified ripple current at both low and high frequency (1.700 A at 120 Hz and 2.431 A at 100 kHz) supports demanding ripple environments.
• Extended High‑Temperature Life — 3000‑hour endurance at 105 °C ensures durability in thermally stressed designs.
• Robust Mounting — Snap‑in, radial can package (φ25×50 mm) provides mechanical stability for through‑hole assemblies and easy installation.
• Measurable Leakage Specification — Leakage current defined (1150 µA) and series leakage formula available (I ≤ 3CV) for predictable DC loss budgeting.
• RoHS Compliant — Aligns with regulations requiring restriction of hazardous substances.
