LNY2W472MSEGBN

The LNY2W472MSEGBN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNY series designed for general-purpose, high-voltage applications. It provides 4.7 mF (4700 µF) capacitance at a 450 V rating in a radial can with screw terminals, targeting equipment that requires robust bulk capacitance with secure electrical connections.

Key value propositions include high voltage capability, substantial ripple-handling performance, a 2000-hour endurance at 85°C, and RoHS compliance—making it suitable for designs where long-term reliability and equipment downsizing are priorities.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance rated at 450 V with ±20% tolerance (120 Hz, 20°C), delivering substantial bulk storage for high-voltage circuits.
• Loss Tangent (tan δ) — Specified tanδ (DF) of 0.25; tanδ measurement referenced at 120 Hz, 20°C in the series datasheet.
• Ripple Current Performance — Rated ripple current of 15.2 A at 120 Hz and 21.28 A at 10 kHz, supporting dynamic load conditions and ripple filtering in high-voltage power stages.
• Reliability & Endurance — Load-life endurance of 2000 hours at 85°C under DC bias plus rated ripple current; designed to meet the series’ endurance criteria after restoration to 20°C.
• Package & Termination — Radial can with screw terminals and M5-compatible bolt mounting; physical dimensions φ63.5 × 145 mm (L: 14.5 × D: 6.35 cm) with terminal-pitch and bracket options per the LNY series.
• Operating Range & Environmental — Rated for operation from −40°C to +85°C and compliant with RoHS (2011/65/EU, (EU)2015/863).
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C), per datasheet guidance.

Typical Applications

• General-purpose high-voltage equipment — Provides bulk capacitance and high-voltage rating for industrial and commercial systems that require polarized aluminum electrolytic capacitors.
• Space-conscious system designs — Higher capacitance in the LNY series is suited for equipment down sizing, helping designers meet compact form-factor requirements.
• High-voltage power modules — Use where rated ripple current and a 2000-hour life at 85°C are important for sustained performance under load.

Unique Advantages

• High-voltage capability: 450 V rating enables use in circuits requiring elevated DC voltage handling without series stacking of components.
• Substantial bulk capacitance: 4700 µF offers significant energy storage for smoothing and decoupling in high-voltage designs.
• Robust ripple handling: Specified ripple currents at both 120 Hz and 10 kHz provide predictable thermal and electrical performance under AC ripple conditions.
• Endurance proven at elevated temperature: 2000-hour life at 85°C under rated conditions supports long-term reliability in thermally demanding environments.
• Screw-terminal mechanical reliability: Radial can with screw terminals and M5-compatible mounting provides secure electrical and mechanical connections for industrial assemblies.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory requirements for many end applications.
