LNX2W103MSEJ

The LNX2W103MSEJ from Nichicon is an aluminum electrolytic, screw-terminal capacitor offering 10,000 µF capacitance at a 450 V rating. Built for high-ripple, extra-high-voltage applications, it is targeted at industrial power systems where sustained ripple current, reliability, and long operational life are required.

As a radial can with screw terminals, this part delivers secure terminations and the thermal and endurance characteristics needed for inverter circuitry and industrial power supplies, while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — Rated ripple current: 23 A at 120 Hz (low frequency) and 32.2 A at 100 kHz (high frequency) to handle demanding AC stress.
• Long Life & Endurance — Designed for 20,000 hours of operation at +85°C under rated ripple current conditions, providing predictable long-term performance.
• Operating Temperature — Specified for continuous operation from −25°C to +85°C; series data shows impedance stability with Z(−25°C)/Z(+20°C) = 8.
• Screw Terminal Package — Radial can with screw terminals for durable, low-impedance electrical connections and robust mechanical mounting.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• Compliance & Safety Options — RoHS compliant; flame-retardant electrolyte types are available within the series.
• Physical Dimensions — Package dimensions: L: 19 × D: 9 cm in a screw-terminal radial can configuration.

Typical Applications

• Industrial Power Supplies — Suited for inverter circuitry and power-supply smoothing where high capacitance and ripple handling are required.
• Extra-High Voltage Systems — 450 V rating (series supports 350–550 V) for use in extra-high-voltage power rails and energy storage stages.
• High-Ripple Environments — Applications with sustained ripple current benefit from the part’s high ripple ratings and 20,000-hour endurance at +85°C.
• General-Purpose Power Electronics — For designs requiring large capacitance in a screw-terminal radial can package for secure, low-impedance connections.

Unique Advantages

• High ripple endurance: Explicit ripple ratings at both 120 Hz and 100 kHz reduce stress and support continuous high-current filtering tasks.
• Predictable long life: 20,000 hours at +85°C under rated ripple current provides clear lifecycle expectations for industrial deployments.
• Robust screw-terminal mounting: Durable mechanical and electrical connections simplify assembly and improve reliability in industrial environments.
• High-voltage capability: 450 V rating and series support up to 550 V enable use in extra-high-voltage designs without changing capacitor family.
• Regulatory and safety options: RoHS compliance and availability of flame-retardant electrolyte types help address environmental and safety considerations.
