LNK2W822MSEH

The LNK2W822MSEH is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose high-voltage applications. It provides 8.2 mF (8200 µF) capacitance at a 450 V rating with a ±20% tolerance, and is RoHS compliant.

Engineered for robust long-term operation, this capacitor supports continuous operation up to 85°C with a specified load life of 5000 hours at 85°C under rated ripple current, making it suitable for designs requiring substantial bulk capacitance and reliable screw-terminal connections.

Key Features

• Core: Capacitance & Voltage — 8.2 mF (8200 µF) nominal capacitance, rated for 450 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Mounting & Package — Screw terminal radial can package designed for secure bolt connections; package dimensions listed as L: 19 × D: 7.62 cm for board/mounting planning.
• Operating Temperature & Endurance — Rated from −25°C to +85°C with a load life of 5000 hours at 85°C when subjected to DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 19.1 A at 120 Hz and 26.74 A at 100 kHz; frequency coefficients provided in the datasheet to scale ripple capability across frequencies.
• Leakage, Insulation & Voltage Proof — Leakage current after 5 minutes is ≤ 3√CV (µA) or 5 mA (whichever is smaller) at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Low-temperature Stability — Impedance stability noted with Z(−25°C)/Z(+20°C) up to 8 (series specification).
• Compliance — RoHS compliant as stated in product data.

Typical Applications

• General-purpose high-voltage systems — Provides large bulk capacitance at 450 V for systems that require energy storage or smoothing in general-purpose high-voltage circuits.
• Power conversion and filtering — Suited for designs where high-capacitance, high-voltage smoothing and ripple current handling are needed under continuous load.
• Industrial equipment — Appropriate for general-purpose industrial applications operating within −25°C to +85°C that require long-life electrolytic capacitance with secure screw-terminal connections.

Unique Advantages

• High-voltage bulk capacitance: 8.2 mF at 450 V provides substantial energy storage in a single component, simplifying high-voltage power-stage designs.
