LNK2H472MSEJBN

The LNK2H472MSEJBN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNK series, engineered for general‑purpose high‑voltage applications. This polarized radial can delivers 4.7 mF (4700 µF) capacitance at a 500 V rating and is optimized for systems that require high ripple handling and extended endurance.

Designed for reliability in demanding environments, the capacitor offers a 5000‑hour load life at 85°C, high ripple current capability across low and high frequencies, and RoHS compliance—making it suitable for production volumes and industrial use.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current Capability — Rated ripple current of 15.8 A at 120 Hz and 22.12 A at 10 kHz, supporting significant AC ripple conditions across frequency ranges.
• Endurance & Temperature Range — Load life of 5000 hours at 85°C; operating temperature range from −25°C to +85°C.
• Low Loss & Leakage — Dissipation factor (tan δ) of 0.2 and measured leakage current of 4590 µA as supplied.
• Robust Mechanical Package — Screw terminal radial can package (φ90×130L; size dimension L: 13 × D: 9 cm) for secure electrical and mechanical connections.
• Compliance & Production Ready — RoHS‑compliant, supplied in cardboard packing and listed for mass production in the LNK series.

Typical Applications

• General‑Purpose Power Electronics — Acts as a high‑voltage energy reservoir and smoothing capacitor where 500 V rating and high ripple capability are required.
• Industrial Equipment — Suitable for industrial power modules and assemblies that demand long endurance at elevated ambient temperatures.
• Bulk Filtering & DC Link — Used for bulk energy storage and DC link filtering in systems that require polarized, high‑capacitance units with robust terminal connections.

Unique Advantages

• High‑Voltage, High‑Capacitance Combination: 4.7 mF at 500 V provides substantial energy storage in a single component, reducing system part count.
• Wide Frequency Ripple Support: Rated ripple currents specified at both 120 Hz and 10 kHz enable predictable performance across low and high frequency conditions.
• Long Endurance at Elevated Temperature: 5000 hours load life at 85°C supports reliable, sustained operation in hot operating environments.
• Screw Terminal Mechanical Integrity: Screw terminal radial can simplifies secure wiring and maintenance compared with leaded or solder‑only terminations.
• Production and Environmental Readiness: Mass production availability and RoHS compliance facilitate volume deployment and regulatory alignment.
