LNT2G103MSEJBB

The LNT2G103MSEJBB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, specified for 10,000 µF at 400 V with a 105°C rating. It is designed for general-purpose power applications that require high ripple-current handling and robust, threaded terminal connections.

Key value comes from its combination of high capacitance and voltage rating, elevated operating temperature capability, and radial can packaging with screw terminals for secure, serviceable mounting.

Key Features

• Capacitance & Voltage — 10,000 µF (10 mF) nominal capacitance at a 400 V rated voltage, suitable where large energy storage and high DC voltage endurance are required.
• High Temperature & Long Life — Rated for operation up to 105°C with a specified lifetime of 5,000 hours at 105°C.
• High Ripple Current — Designed for elevated ripple workloads: 32.9 A at 120 Hz (low frequency) and 46.06 A at 100 kHz (high frequency).
• Mechanical / Mounting — Radial can with screw terminals (φ90 × 190L form factor) for sturdy, low-resistance connections and straightforward installation.
• Temperature Range & Impedance Stability — Operating range listed as −25°C to 105°C; series specifications note impedance stability metrics at low temperature for rated voltage ranges.
• Polarized & Tolerance — Polarized electrolytic capacitor with capacitance tolerance of −20% to +20%.
• Compliance & Packaging — RoHS compliant and supplied in cardboard packing for mass production environments.

Typical Applications

• Power supply smoothing — Bulk energy storage and smoothing in high-voltage DC power supplies where 400 V rating and high capacitance are needed.
• Power conversion and inverters — DC link and filtering in power conversion stages that demand high ripple current capability and elevated temperature endurance.
• Industrial power subsystems — General-purpose use in industrial equipment requiring robust screw-terminal connections and long-life performance at 105°C.

Unique Advantages

• High energy density at elevated voltage: 10,000 µF at 400 V provides substantial bulk capacitance for high-voltage circuits without multiple parallel parts.
• Designed for ripple-heavy environments: Specified ripple current ratings at 120 Hz and 100 kHz support demanding AC ripple conditions and switching power topologies.
• Robust screw-terminal mounting: Screw terminals offer low-resistance, serviceable connections suitable for heavy-current applications and easy replacement.
• Elevated temperature endurance: 105°C rating and 5,000-hour lifetime at that temperature support sustained operation in thermally aggressive installations.
• Compliance and production-ready packaging: RoHS compliant and supplied in cardboard packing for streamlined handling in volume manufacturing.
