LNY2V472MSEFBN

The LNY2V472MSEFBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering 4.7 mF (4700 µF) capacitance at a 350 V rating. It is a radial can with screw terminals (M5 bolt nominal terminal) designed for general purpose applications that benefit from high capacitance and secure power connections.

Key value propositions include high-voltage energy storage in a compact φ51 × 140 mm package, a rated operating temperature range of –40°C to +85°C, and a specified load life of 2000 hours at 85°C under rated ripple current, enabling predictable performance in demanding operating conditions.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a 350 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Screw Terminal Package — Radial can with screw terminals and M5 nominal bolt diameter for secure, low-impedance power connections.
• Thermal and Life Rating — Rated for –40°C to +85°C operation and a load life of 2000 hours at 85°C when operated with rated ripple current.
• Ripple Current Capability — Specified ripple currents of 15.9 A at 120 Hz and 22.26 A at 10 kHz to manage AC ripple heating under typical filtering conditions.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) specified at 0.25; leakage current after 5 minutes is not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• Electrical Robustness — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• Compact Mechanical Footprint — Size φ51 × 140 mm (L: 14 × D: 5.1 cm) suitable where high capacitance is required in a constrained radial can form factor.
• RoHS Compliant — Manufactured to comply with RoHS directives.

Typical Applications

• General Purpose Power Systems — Use wherever a 4700 µF, 350 V polarized capacitor is required for energy storage or smoothing in general purpose equipment.
• Equipment Downsizing — Part of the LNY series which is suited for equipment downsizing by delivering high capacitance in a compact φ51 × 140 mm can.
• Screw-Terminal Power Connections — Ideal for systems that need secure screw-terminal mounting and robust ripple-current handling for power filtering tasks.

Unique Advantages

• High Voltage, High Capacitance — 4.7 mF at 350 V delivers substantial stored charge for high-voltage filtering and energy-hold requirements.
• Designed for Endurance — 2000 hours load life at 85°C under rated ripple current provides predictable long-term behavior in elevated-temperature environments.
• Measured Ripple Performance — Defined ripple current ratings at 120 Hz and 10 kHz help manage self-heating and performance in AC ripple conditions.
• Secure Mechanical and Electrical Connections — Screw-terminal radial can with M5 nominal bolt offers reliable mounting and low-impedance power termination.
• Verified Insulation and Voltage Withstand — Insulation resistance and AC 2500 V voltage proof between terminal and bracket reduce risk of dielectric issues in installed systems.
• Regulatory Compliance — RoHS compliance supports environmentally regulated product designs.
