LNK2H472MSEJBB

The LNK2H472MSEJBB is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNK series. It provides 4.7 mF (4700 µF) capacitance at a 500 V rated voltage in a radial can with screw terminals, designed for general‑purpose high‑voltage applications that require bulk capacitance and robust terminal connections.

This part combines a compact φ90×130L package with specifications optimized for sustained ripple current and long endurance: rated for operation from −25°C to 85°C with a 5000‑hour life at 85°C under rated ripple conditions.

Key Features

• High Capacitance, High Voltage — 4.7 mF (4700 µF) capacitance rated at 500 V for bulk energy storage in high‑voltage circuits.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low‑resistance connections for heavy‑current or serviceable installations.
• Elevated Ripple Handling — Rated ripple current of 15.8 A at 120 Hz and 22.12 A at 10 kHz supports high ripple applications within specified frequency bands.
• Endurance at Elevated Temperature — Load life of 5000 hours at 85°C when DC bias plus rated ripple current is applied, with post‑test capacitance within ±20% of initial value.
• Controlled Dissipation and Leakage — Specified tangent of loss angle (tan δ) of 0.2 and leakage current listed at 4590 µA for predictable electrical performance.
• Operating Range and Tolerance — Polarized device with operating temperature −25°C to 85°C and capacitance tolerance ±20% (120 Hz, 20°C).
• Regulatory Compliance — RoHS compliant as noted for the LNK series.

Typical Applications

• High‑voltage power supplies — Bulk capacitance and 500 V rating support DC bus and smoothing functions in high‑voltage supply designs.
• Industrial power conversion — Screw‑terminal construction and high ripple ratings suit applications requiring secure connections and sustained ripple current handling.
• Energy storage and DC link — Large capacitance and rated voltage make this part suitable for DC link, bulk energy storage, and decoupling in power electronics.

Unique Advantages

• High voltage and large capacitance in a compact package: 4700 µF at 500 V in a φ90×130L can provides significant bulk storage without exceeding the LNK series’ smaller‑sized footprint.
• Robust screw‑terminal interface: Facilitates secure mechanical and electrical connections for heavy current paths and field serviceability.
• Designed for sustained ripple loading: Specified ripple current values at both low and high frequencies (15.8 A @120 Hz, 22.12 A @10 kHz) enable predictable thermal and electrical behavior under ripple stress.
• Long endurance under rated conditions: 5000 hours at 85°C with DC bias plus ripple current provides a defined lifecycle for thermal/ripple‑intensive applications.
• Verified electrical characteristics: Controlled tan δ (0.2) and specified leakage current (4590 µA) support reliable circuit design and sizing.
• RoHS compliant: Meets RoHS directive requirements as indicated for the LNK series.
