LNK2G472MSEG

The LNK2G472MSEG is an aluminum electrolytic capacitor in a screw-terminal can designed for general-purpose power applications. It delivers 4.7 mF (4700 µF) capacitance at a 400 V rating with ±20% tolerance, combining high-voltage capability and large bulk capacitance for power filtering and energy storage.

Built to the LNK series specification, this screw-terminal type is targeted at industrial and commercial power systems that require robust ripple performance, long life at elevated temperature, and secure mechanical termination.

Key Features

• Electrical Capacity — 4.7 mF (4700 µF) nominal capacitance at 400 V rated voltage, suitable for high-voltage bulk filtering and energy-holding functions.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C, allowing predictable design margins for filtering and hold-up calculations.
• High Ripple Current Capability — Rated ripple current of 14.8 A at 120 Hz (low frequency) and 20.72 A at 10 kHz (high frequency), supporting demanding AC ripple environments.
• Loss Characteristics — tan δ = 0.2 (measurement at 20°C, 120 Hz), providing a defined dissipation profile for thermal and stability planning.
• Leakage Current — Specified leakage current of 4,110 µA, measured after rated voltage application and useful for standby and no-load loss estimates.
• Thermal and Life Rating — Rated for operation from −25°C to +85°C with an endurance (load life) of 5,000 hours at 85°C under applied ripple and D.C. bias conditions.
• Screw Terminal Mounting — Radial can with screw terminals (M5 nominal bolt for φ63.5 case), ensuring secure, low-impedance connections for high-current applications.
• Mechanical Size — Compact LNK-series footprint: φ63.5 × 130 mm overall (approx. L: 13 cm × D: 6.35 cm), designed for smaller-sized installations within the series.
• RoHS Compliant & Production Ready — RoHS status compliant and supplied in cardboard packing for mass production deployment.

Typical Applications

• Industrial Power Supplies — Bulk filtering and hold-up capacitance for high-voltage supply rails in industrial converters and power cabinets.
• Power Conversion Equipment — Energy storage and ripple smoothing in rectifier stages and DC link circuits for inverters and converters.
• UPS and Backup Systems — Bulk charge storage and transient suppression supporting system hold-up during short interruptions.
• Commercial Power Conditioning — Filtering and smoothing in commercial-grade power modules and conditioning assemblies.

Unique Advantages

• High-voltage bulk capacitance: 400 V rating with 4700 µF provides significant energy storage in a single component, simplifying board-level design.
• Screw-terminal robustness: M5 screw-terminal mounting offers secure, low-resistance connections for high-current ripple and reliable mechanical retention.
• Designed for elevated-temperature operation: 5,000-hour endurance at 85°C supports long-term reliability under sustained thermal and ripple stress.
• Clear electrical parameters: Defined tan δ, leakage current, and frequency-dependent ripple ratings enable accurate thermal and life modelling.
• Compact LNK-series footprint: φ63.5 × 130 mm size provides a smaller-sized option within high-voltage, high-capacitance product choices for space-constrained designs.
• RoHS compliance and production packaging: Meets RoHS requirements and is supplied for mass production, facilitating procurement and assembly workflows.
