LNT2W103MSEJBB

The LNT2W103MSEJBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series. It delivers 10,000 µF capacitance at a 450 V rated voltage in a φ90 × 220L can with radial screw terminals for secure mechanical and electrical connections.

Designed for general-purpose power applications, this capacitor offers high ripple-current capability and a robust thermal life (5,000 hours at 105°C), making it suitable for demanding power-conditioning, bulk energy storage and smoothing roles in industrial and commercial equipment.

Key Features

• Capacitance & Voltage — 10,000 µF rated capacitance at 450 V, with ±20% tolerance for predictable bulk energy storage.
• Screw Terminal Package — Radial can with screw terminals provides secure, high-current connection and simplified mounting for heavy-current bus applications.
• High Ripple Current — Rated ripple current of 35.1 A at 120 Hz and 49.14 A at 100 kHz to support power supply smoothing and high-frequency ripple conditions.
• Thermal Performance & Lifetime — Rated for continuous operation from −25°C to +105°C with a load life of 5,000 hours at 105°C under rated ripple conditions.
• Leakage & Loss Characteristics — Specified leakage current of 5000 µA and tan δ of 0.2 (measured at 120 Hz), enabling predictable loss and warm-up behavior.
• Robust Mechanical Footprint — Large φ90 × 220L can (approx. L: 22 cm × D: 9 cm) suitable for high-energy-density designs that require stable mounting and high-voltage capability.
• Compliance — RoHS compliant as specified in product data.

Typical Applications

• Power supply filtering — Bulk smoothing and energy storage in high-voltage power supplies where 450 V rating and large capacitance are required.
• Industrial power electronics — DC link and filter applications that need high ripple-current handling and a 105°C rated operating temperature.
• Energy storage and smoothing — Applications requiring large capacitance and secure screw-terminal connections for reliable high-current cycling.

Unique Advantages

• High voltage with large capacitance: 450 V rating combined with 10,000 µF provides substantial stored energy per component for compact high-voltage designs.
• Designed for high ripple environments: 35.1 A (120 Hz) and 49.14 A (100 kHz) ripple-current ratings reduce the need for parallel components in many designs.
• Long operational life at elevated temperature: 5,000 hours at 105°C under rated ripple and DC bias supports long-term reliability in hot operating environments.
• Secure, serviceable connections: Screw terminal mounting simplifies installation, maintenance and high-current terminations on heavy-duty boards and busbars.
• Predictable electrical behavior: Specified tan δ and leakage current figures support deterministic thermal and loss budgeting in power designs.
• RoHS compliant: Meets environmental directive requirements for restricted substances as noted in the product data.
