LNY2G472MSEGBB

The LNY2G472MSEGBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series. It provides 4,700 µF capacitance at a 400 V rating in a radial can with M5 screw terminals, designed for general-purpose power applications that require high-capacitance bulk storage and robust ripple handling.

Key value propositions include a high-voltage 400 V rating, substantial ripple-current capability, a 2,000-hour endurance at 85°C, and a compact φ63.5 × 125 mm form factor for applications where footprint and reliable power buffering are important.

Key Features

• Capacitance & Voltage — 4.7 mF (4,700 µF) rated at 400 V provides significant bulk energy storage for high-voltage DC systems.
• Tolerance & Loss — ±20% capacitance tolerance (120 Hz, 20°C) with tan δ (DF) = 0.25, specified for predictable AC performance.
• High Ripple Current Capability — Rated ripple current of 16.1 A at 120 Hz and 22.54 A at 10 kHz supports demanding ripple conditions in power conversion and filtering.
• Endurance & Temperature — Load life of 2,000 hours at 85°C under rated ripple current; operating temperature range from −40°C to +85°C.
• Package & Mounting — Radial can with screw terminals (M5) simplifies electrical connections and mechanical mounting; nominal dimension L: 12.5 × D: 6.35 cm (φ63.5 × 125 mm).
• Electrical Reliability — Leakage current specified as not more than 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, and voltage proof of AC 2500 V for 1 minute with no abnormality.
• Regulatory — RoHS compliant.
• Designed for Compact Equipment — LNY series notes suitability for equipment downsizing while maintaining high capacitance and reliability.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high-voltage DC power supplies and rectifier stages where 400 V capability and high ripple handling matter.
• Power Conversion & Inverters — DC-link and filtering in inverters and converters that require substantial capacitance at elevated voltages and sustained ripple currents.
• Uninterruptible Power Supplies (UPS) and Energy Storage — Bulk filtering and energy buffering for commercial UPS and standalone power systems.
• Commercial & Industrial Electronics — General-purpose high-voltage applications where long life at elevated temperature and robust mechanical mounting are needed.
