LNK2H472MSEJ

The LNK2H472MSEJ is a screw-terminal aluminum electrolytic capacitor offering 4.7 mF (4700 µF) capacitance at a 500 V rating in a radial can package. It is designed for general-purpose applications that require high-voltage bulk capacitance, secure screw-terminal connections and sustained ripple handling.

Key value propositions include high-voltage energy buffering, robust mechanical termination via screw terminals, a 5000-hour load life at 85°C, and RoHS compliance—delivered in a φ90 × 130 mm form factor for compact high-capacity installations.

Key Features

• High-voltage bulk capacitance — 4.7 mF (4700 µF) rated at 500 V for bulk energy storage and smoothing in high-voltage circuits.
• Screw terminal package — Radial can with screw terminals (M5 nominal bolt size per series drawing) for secure, low-impedance mechanical and electrical connections.
• Rated temperature and life — Specified for operation from −25°C to +85°C with an endurance rating of 5000 hours at 85°C under rated ripple current.
• Ripple current capability — 15.8 A at 120 Hz and 22.12 A at 10 kHz; frequency coefficients available (120 Hz = 1.00, 10 kHz or more = 1.40) to size ripple margins across frequency.
• Electrical characteristics — Polarized capacitor with ±20% capacitance tolerance (at 120 Hz, 20°C), tan δ = 0.2, and listed leakage current of 4590 µA; datasheet leakage limit follows the standard 3√CV (µA) or 5 mA rule after 5 minutes at 20°C.
• Insulation and voltage proof — Insulation resistance specified >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket per datasheet.
• Form factor and packaging — φ90 × 130 mm (L: 13 cm × D: 9 cm) radial can; supplied in cardboard packing for mass-production deliveries.
• RoHS compliant — Meets RoHS directive requirements as stated in product documentation.

Typical Applications

• Power supply filtering — Provides high-voltage bulk capacitance and ripple smoothing for general-purpose power-supply designs.
• DC link / bus energy storage — Suited for DC bus stabilization where 500 V rating and multi-millifarad capacitance are required.
• Industrial power electronics — Used in general-purpose industrial equipment that requires robust screw-terminal mounting and sustained ripple endurance.

Unique Advantages

• High-voltage, high-capacity solution: 4.7 mF at 500 V provides substantial energy buffering in a single component, reducing the need for parallel banks.
• Secure termination: Screw-terminal design with M5 nominal bolt sizing ensures reliable mechanical and electrical connection for heavy-current installations.
• Designed for continuous ripple: Rated ripple currents at 120 Hz and 10 kHz plus frequency coefficients enable predictable thermal and life planning under AC stress.
• Proven endurance: 5000-hour load life at 85°C under rated ripple current supports long-term deployment in sustained-duty environments.
• Clear electrical performance data: Specified tan δ, leakage current and insulation resistance figures allow precise circuit design and verification.
• Regulatory compliance and production readiness: RoHS-compliant construction and cardboard packing for mass-production supply chains.
