The LNK2H472MSEHBN is an aluminum electrolytic capacitor in a screw-terminal can designed for general-purpose high-voltage applications. It delivers 4.7 mF (4700 µF) capacitance at a 500 V rating in a radial can with screw terminals, providing a compact high-capacitance solution for equipment that requires high-voltage energy storage and ripple handling.

Key design attributes include a temperature range of -25°C to 85°C, a rated lifetime of 5000 hours at 85°C under rated ripple conditions, and RoHS compliance—making it suitable where durable, high-voltage bulk capacitance is required.

Key Features

• High Capacitance and Voltage: 4.7 mF (4700 µF) at 500 V rated voltage for high-voltage bulk energy storage and decoupling in compact form.
• Screw Terminal Mounting: Radial can with screw terminals provides robust, low-impedance connections for high-current and maintenance-friendly installation.
• Temperature and Endurance: Operates from -25°C to +85°C with a specified life of 5000 hours at 85°C under rated ripple current conditions.
• Ripple Current Capability: Rated ripple current of 16.5 A at 120 Hz and 23.1 A at 10 kHz, with a frequency coefficient table provided for other frequencies.
• Leakage and Loss Characteristics: Measured leakage current 4.59 mA and tangent of loss angle (tan δ) 0.2 to help designers size self-discharge and dissipation budgets.
• Polarized Can Package: Polarized aluminum electrolytic in a φ76.2 × 170 mm can (dimensions L: 17 cm × D: 7.62 cm) with radial screw terminals for secure mechanical mounting.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• General-purpose power systems: Use where 4.7 mF at 500 V and substantial ripple current capability are required for bulk energy storage or smoothing.
• Industrial power electronics: High-voltage filtering and decoupling in assemblies benefiting from screw-terminal connections and high ripple endurance.
• High-voltage DC circuits: Energy storage and stabilization where polarized high-capacitance components are needed within the -25°C to 85°C operating window.

Unique Advantages

• High-voltage, high-capacitance in a compact can: 4700 µF at 500 V provides substantial stored energy density for space-constrained high-voltage designs.
• Robust electrical endurance: Rated for 5000 hours at 85°C under ripple, enabling predictable lifetime planning in sustained high-stress environments.
• Strong ripple handling: 16.5 A (120 Hz) and 23.1 A (10 kHz) ripple ratings help reduce temperature rise and extend component life under AC-ripple conditions.
• Secure screw-terminal connectivity: Mechanical reliability and low contact resistance for assemblies requiring frequent service or heavy current flow.
• Clear thermal and loss metrics: Specified tan δ of 0.2 and measured leakage current of 4.59 mA allow accurate thermal and leakage budgeting in system design.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted-substance conformance.
