The LNX2W123MSEJBB is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNX series designed for high‑voltage, high‑ripple applications. It provides 12,000 µF capacitance at a 450 V rating in a radial can with screw terminals, targeting industrial power electronics where sustained ripple performance and long operational life are required.

Built for inverter circuitry and industrial power supplies, this part emphasizes high ripple handling, extended endurance at elevated temperatures, and RoHS compliance for regulated environments.

Key Features

• Capacitance & Voltage — 12 mF (12,000 µF) rated at 450 V for bulk energy storage and DC bus applications.
• High Ripple Current — Rated ripple current of 26.9 A at 120 Hz and 37.66 A at 100 kHz for demanding power conversion workloads.
• Long Life Endurance — Specified for 20,000 hours of operation at +85°C when subjected to rated ripple current, supporting extended maintenance intervals.
• Operating Temperature — Specified range from −25 °C to +85 °C for industrial ambient conditions.
• Tolerance & Polarity — Capacitance tolerance of −20% to +20%; polarized design for correct DC orientation.
• Package & Mounting — Radial can with screw terminals for secure, high‑current connections; physical size listed as L: 22 × D: 9 cm for system layout planning.
• Safety & Environmental — RoHS compliant; flame‑retardant electrolyte option available in the LNX series.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high‑voltage power supplies used in factory and process control equipment.
• Inverter Circuits — DC link and ripple filtering for inverter drive stages where sustained ripple current and voltage hold are needed.
• High‑Voltage Power Conversion — Energy buffering and stabilization in converters and power modules operating at extra‑high voltages.

Unique Advantages

• High ripple capability: Explicit ripple current ratings at both 120 Hz and 100 kHz enable designers to size capacitors against measured ripple spectra.
• Extended operational life: 20,000‑hour endurance at +85 °C under rated ripple current reduces replacement frequency in continuous‑duty applications.
• Robust screw‑terminal mounting: Screw terminals deliver reliable, low‑impedance connections for high‑current installations and simplify field wiring.
• High‑voltage rating: 450 V specification supports extra‑high voltage DC bus designs without the need for series stacking of lower‑voltage parts.
• Regulatory conformity: RoHS compliance and optional flame‑retardant electrolyte help meet environmental and safety requirements.
