LNY2V472MSEFBB

The LNY2V472MSEFBB from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNY series, offering 4.7 mF capacitance at a 350 V rated voltage. Designed as a high‑capacitance, screw‑terminal can for general‑purpose power applications, it supports equipment downsizing while delivering high ripple current capability and extended endurance.

Key characteristics include a wide operating temperature range of –40°C to +85°C, 2000 hours rated life at 85°C under rated ripple conditions, and RoHS compliance — making it suitable for a range of industrial and power electronics designs that require robust bulk capacitance and reliable performance.

Key Features

• High bulk capacitance: 4.7 mF (4700 µF) rated capacitance with ±20% tolerance (120 Hz, 20°C), providing substantial energy storage for power systems.
• High voltage rating: Rated for 350 V operation to support medium‑voltage power and conversion circuits.
• Screw‑terminal package: Radial can with screw terminals and M5 nominal bolt for secure, low‑impedance connections and easy mounting in heavy‑current installations.
• Ripple current capability: Rated ripple current of 15.9 A at 120 Hz and 22.26 A at 10 kHz to handle AC superimposed currents and smoothing duties.
• Endurance and temperature: 2000 hours endurance at 85°C with rated ripple current applied; operational range from –40°C to +85°C for broad environmental tolerance.
• Loss characteristics: Tangent of loss angle (tan δ) specified at 0.25 (measurement conditions per datasheet), enabling predictable dissipation behavior.
• Insulation and dielectric integrity: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; dielectric withstand tested to AC 2500 V for 1 minute between terminal and bracket.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA, whichever is smaller.
• Compact, higher‑capacitance form factor: φ51 × 140 mm (diameter 51 mm, length 140 mm) to support equipment downsizing where higher capacitance is required.
• Regulatory compliance and marking: RoHS compliant with white lettering on a black sleeve for clear identification; shipped in cardboard packing for production handling.

Typical Applications

• General‑purpose power filtering: Bulk energy storage and smoothing where high capacitance and rated ripple current improve voltage stability and reduce ripple on DC rails.
• Industrial power equipment: Used in power conversion and control systems that require a robust, screw‑terminal capacitor for high current connections and durable mounting.
• Energy smoothing and backup: Provides capacitance and voltage rating suitable for short‑term energy buffering and smoothing in power subsystems.

Unique Advantages

• High energy density at medium voltage: 4700 µF at 350 V supplies substantial stored energy in a φ51 × 140 mm package to support compact power designs.
• Strong ripple handling: Rated ripple currents of 15.9 A (120 Hz) and 22.26 A (10 kHz) help maintain performance under heavy AC loading.
• Durability under elevated temperature: 2000 hours rated life at 85°C with applied ripple current gives designers predictable long‑term behavior in hotter operating environments.
• Robust electrical isolation: Insulation resistance >100 MΩ at DC 500 V and 2500 V AC voltage proof between terminal and bracket support safe, reliable installations.
• Secure mechanical connections: Screw‑terminal can with M5 nominal bolt and 22.0 mm terminal pitch (for φ51) enables low‑impedance, mechanically robust terminations.
• Regulatory alignment: RoHS compliance and clear sleeve marking simplify assembly and regulatory documentation.
