LNK2W102MSEFBB

The LNK2W102MSEFBB is a screw-terminal, radial can aluminum electrolytic capacitor in Nichicon’s LNK series. It provides 1000 µF capacitance at a 450 V rating with a compact screw-terminal package designed for general-purpose high-voltage applications.

Engineered for sustained operation, this capacitor supports defined ripple currents at multiple frequencies and a 5000-hour life at 85°C, offering a clear specification set for designers of high-voltage DC systems and industrial power electronics.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable where substantial high-voltage bulk capacitance is required.
• Screw-Terminal Mounting — Radial can with screw terminals for robust mechanical and electrical connections in rack-mounted or enclosure-installed equipment.
• Ripple Current Capability — Rated ripple currents of 5.20 A at 120 Hz and 7.28 A at 10 kHz, enabling effective AC ripple handling across low and high frequency ranges.
• Operating Temperature & Lifetime — Specified for operation from −25°C to +85°C with a rated load-life of 5000 hours at 85°C under rated ripple and DC bias.
• Reliability Metrics — Endurance after 5000 hours at 85°C: capacitance change within ±20% of initial value; tan δ up to 300% of initial specified value; leakage current not exceeding initial specified value.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (C = µF, V = V), providing a measurable limit for bias current planning.
• Insulation & Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Package & Marking — φ51 × 75 mm can (L: 7.5 × D: 5.1 cm) with white lettering on a black sleeve for clear identification; M5 nominal bolt for terminal connections.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing for high-voltage DC circuits where a 450 V, 1000 µF capacitor is required.
• Industrial power electronics — Use in industrial converters and power cabinets that require screw-terminal mounting and sustained operation up to 85°C.
• High-voltage DC link filtering — DC bus filtering and ripple attenuation where specified ripple current ratings at 120 Hz and 10 kHz are needed.

Unique Advantages

• High-voltage bulk capacitance: 1000 µF at 450 V provides substantial stored energy for DC systems without the need for paralleling multiple smaller components.
• Screw-terminal robustness: Mechanical and electrical reliability for heavier bus connections and serviceable assemblies.
• Defined ripple performance: Explicit ripple current ratings at 120 Hz and 10 kHz allow designers to plan for both mains-frequency and high-frequency ripple environments.
• Long life at elevated temperature: 5000 hours at 85°C under rated ripple and DC bias offers a predictable endurance baseline for thermal and lifetime budgeting.
• Measurable leakage and insulation specs: Clear leakage-current limits and insulation resistance/voltage-proof values support safety and sizing of bias networks and isolation considerations.
• RoHS compliance: Material compliance simplifies environmental and regulatory assessments.
