LNK2W472MSEGBB

The LNK2W472MSEGBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power electronics. It provides 4700 µF capacitance at a 450 V rating with ±20% tolerance and polarized terminals for DC applications.

Engineered for high-ripple, high-voltage environments, this part delivers substantial ripple-current capability (15.6 A at 120 Hz; 21.84 A at 10 kHz), a 5000-hour endurance at 85°C, and RoHS compliance. Its φ63.5 × 155 mm form factor and screw-terminal mounting suit robust power assemblies where secure, high-current connections are required.

Key Features

• Capacitance and Voltage — 4700 µF (4.7 mF) nominal capacitance at a rated voltage of 450 V with ±20% tolerance.
• Screw Terminal Package — Radial can with screw terminals for secure mechanical and electrical connection in high-current applications.
• High Ripple-Current Capability — Rated ripple current of 15.6 A at 120 Hz (low frequency) and 21.84 A at 10 kHz (high frequency), supporting heavy AC stress on DC link and smoothing stages.
• Leakage Current — Specified leakage current of 4360 µA, measured under the product’s test conditions.
• Endurance and Temperature Range — 5000 hours of load-life endurance at 85°C; operating temperature range −25°C to 85°C.
• Form Factor and Mounting — φ63.5 × 155 mm size (L: 155 mm × D: 63.5 mm) in a radial can; supplied with screw-terminal mounting and cardboard packing for mass production handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High-Voltage DC Power Supplies — Bulk energy storage and smoothing at a 450 V system voltage using 4700 µF capacitance.
• Industrial Power Conversion — DC-link and filter applications that demand high ripple-current tolerance and robust screw-terminal connections.
• Energy Storage and Backup Systems — Bulk capacitance for short-term energy buffering where endurance and voltage rating are critical.
• General-Purpose Power Electronics — Systems requiring a high-voltage polarized capacitor for filtering, smoothing, and energy storage in a screw-terminal package.

Unique Advantages

• High voltage and large capacitance: 450 V rating with 4700 µF provides substantial stored energy per component for compact high-voltage designs.
• Robust ripple handling: 15.6 A at 120 Hz and 21.84 A at 10 kHz support rigorous AC loading scenarios and reduce the need for parallel parts.
• Long endurance at elevated temperature: 5000-hour rated life at 85°C gives predictable long-term performance under sustained thermal and electrical stress.
• Screw-terminal reliability: Screw terminals simplify secure, low-resistance connections for high-current bus implementations and serviceability.
• Regulatory compliance: RoHS compliance supports deployment in regions requiring restricted-substance conformance.
