LNK2W472MSEHBB

The LNK2W472MSEHBB from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNK series designed for general-purpose power applications. It delivers 4700 µF (4.7 mF) capacitance at a 450 V rating with a rugged screw-terminal can package and is produced for mass production with cardboard packing.

Key value comes from its high working voltage, substantial ripple-current capability at both low and high frequencies, and a 5000-hour rated life at 85°C—making it suitable where reliable bulk energy storage and high-voltage smoothing are required.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) rated at 450 V for high-voltage bulk storage and smoothing.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-impedance connections in power assemblies.
• High Ripple Current Capability — 15.1 A at 120 Hz (low frequency) and 21.14 A at 10 kHz (high frequency) to support heavy AC ripple and switching applications.
• Endurance — 5000 hours life rating at 85°C under rated ripple current and DC bias.
• Operating Temperature Range — −25°C to +85°C for a wide ambient operating envelope.
• Leakage & Loss — Specified leakage current of 4360 µA and a tangent of loss angle (tan δ) of 0.2 for predictable performance.
• Tolerance & Polarization — ±20% capacitance tolerance; polarized electrolytic construction.
• Size & Mechanical — Can dimensions φ76.2 × 115 mm (L: 11.5 cm × D: 7.62 cm) to fit screw-terminal power modules.
• Compliance — RoHS compliant.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage at up to 450 V DC, leveraging the 4700 µF capacitance and high ripple-current rating.
• Switch-mode power converters — DC-link and output filtering where high ripple current at both low (120 Hz) and high (10 kHz) frequencies is required.
• Industrial power electronics — Rugged screw-terminal mounting and a 5000-hour endurance at 85°C suit sustained operation in industrial converter racks and assemblies.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage DC systems without series stacking.
• Robust ripple handling: Specified ripple currents of 15.1 A (120 Hz) and 21.14 A (10 kHz) reduce thermal stress in high-switching environments.
• Long endurance at elevated temperature: 5000-hour life at 85°C supports predictable aging and maintenance planning.
• Screw-terminal reliability: Secure mechanical and electrical connections for high-current bus applications.
• Measured leakage and loss characteristics: Listed leakage current (4360 µA) and tan δ (0.2) help designers model standby losses and ESR-related heating.
• RoHS compliance: Meets environmental directive requirements for lead-free assembly environments.
