LNX2W103MSEJBB

The LNX2W103MSEJBB is an aluminum electrolytic capacitor in Nichicon’s LNX series designed for high-voltage, high-ripple industrial power applications. This screw-terminal, radial can capacitor provides 10,000 µF capacitance at a 450 V rating and is specified for long-term operation at elevated temperatures.

Built for general-purpose and industrial power-supply duty—including inverter circuitry—the part combines high ripple capability and extended lifetime to support reliable DC-link and smoothing applications in demanding environments.

Key Features

• High Capacitance: 10,000 µF (10 mF) provides substantial energy storage for filtering and DC-link smoothing.
• Extra-High Voltage Rating: 450 V rated voltage suitable for high-voltage power electronics and inverter systems.
• Long Lifetime: Specified 20,000 hours at +85°C when operating at rated ripple current, supporting extended maintenance intervals.
• High Ripple Current Capability: 23 A at 120 Hz and 32.2 A at 100 kHz, enabling effective handling of high AC ripple in power-conversion circuits.
• Screw-Terminal Mounting: Radial can package with screw terminals for secure, low-inductance electrical connections in power assemblies.
• Operating Range and Tolerance: Operating temperature −25°C to +85°C with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Polarized Electrolytic: Designed as a polarized aluminum electrolytic capacitor for DC applications.
• RoHS Compliant: Meets RoHS directive requirements.
• Physical Size: φ90 × 190L form (listed dimensions L: 19 cm × D: 9 cm) suitable for high-capacitance, high-voltage layouts.
• Flame-Retardant Option: Flame retardant electrolyte types are available in the LNX series.

Typical Applications

• Industrial Power Supplies: Used for DC-link smoothing and energy buffering in high-voltage industrial supplies where long life and high ripple handling are required.
• Inverter Circuits: Suited for inverter circuitry requiring extra-high voltage components and robust ripple current performance.
• General-Purpose Power Systems: Applies to general-purpose high-voltage power electronics that need large capacitance and reliable long-term operation.

Unique Advantages

• Extended operational life: 20,000-hour endurance at 85°C under rated ripple current reduces replacement frequency and lowers lifecycle maintenance costs.
• High ripple capability: Rated ripple currents at both low and high frequencies handle demanding AC stress in power-conversion environments.
• High-voltage readiness: 450 V rating supports designs that operate at elevated DC voltages without requiring series stacking of lower-voltage capacitors.
• Secure, low-inductance connections: Screw-terminal radial can package enables robust mechanical and electrical connections in heavy-current assemblies.
• Regulatory compliance: RoHS compliance supports use in regulated product lines and corporate environmental requirements.
• Mass-production availability: Supplied in cardboard packing and intended for mass production, easing procurement for volume programs.
