LNT2W103MSEJ

The LNT2W103MSEJ is an aluminum electrolytic capacitor in Nichicon’s LNT series, featuring a screw terminal radial can package. It delivers 10,000 µF capacitance at a 450 V rating with a 105°C standard operating temperature and is designed for general-purpose power applications.

Built for high ripple environments and extended load life, this screw-terminal capacitor targets use in systems that require high-voltage bulk capacitance, robust ripple handling, and long-term thermal endurance.

Key Features

• High Capacitance & Voltage — 10,000 µF nominal capacitance at a 450 V rated voltage provides substantial bulk energy storage for high-voltage designs.
• 105°C Temperature Rating — Rated for operation up to 105°C (category temperature –25 to +105°C for 160–500 V), enabling deployment in elevated-temperature environments.
• High Ripple Current — Rated ripple current of 35.1 A at 120 Hz and 49.14 A at 100 kHz supports demanding AC ripple and switching applications.
• Long Load Life — Load life specified at 5,000 hours at 105°C under rated ripple and DC bias, supporting longer maintenance intervals and reliability in continuous-duty systems.
• Screw Terminal Mounting — Radial, can-style package with screw terminals for secure electrical and mechanical connections in panel- or chassis-mounted power assemblies.
• Polarized Electrolytic — Polarized design suitable for DC bulk storage and smoothing applications; capacitance tolerance ±20% at 120 Hz, 20°C.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances compliance.
• Compact Form Factor — Size listing (L: 22 × D: 9 cm) for designers to account for footprint in high-energy density assemblies.

Typical Applications

• High-Voltage Power Supplies — Bulk capacitance and 450 V rating support smoothing and energy storage in high-voltage DC power systems.
• Power Conversion & Inverters — High ripple current capability suits switched-mode and inverter front-end filtering in industrial power equipment.
• Industrial Equipment — 105°C rating and 5,000-hour load life at elevated temperature make it suitable for continuous-duty industrial power assemblies.

Unique Advantages

• Large Energy Storage: 10,000 µF at 450 V provides significant bulk capacitance to stabilize DC buses and absorb energy transients.
• Designed for High-Ripple Environments: Specified ripple current at both low and high frequencies (35.1 A at 120 Hz, 49.14 A at 100 kHz) helps reduce heating and extend component life under switching loads.
• Extended Thermal Endurance: 105°C rating combined with a 5,000-hour load life at that temperature supports long-term reliability in hot operating conditions.
• Robust Mechanical Connection: Screw terminal package simplifies secure electrical connections and mechanical mounting for chassis- or bracket-mounted installations.
• Regulatory Compliance: RoHS conformity reduces material restrictions risk and simplifies regulatory assessment for assemblies.
