LNX2V122MSEFBB

The Nichicon LNX2V122MSEFBB is a screw‑terminal aluminum electrolytic capacitor in the LNX series, offering 1,200 µF capacitance at 350 V with polarized construction. Designed for industrial power electronics, it targets inverter circuitry and other high‑ripple, extra‑high‑voltage applications where long operational life and robust terminal connections are required.

This part combines high rated voltage and high ripple capability with extended endurance—specified for 20,000 hours at +85°C under rated ripple conditions—making it suitable for demanding power supply and power conversion environments.

Key Features

• High Rated Voltage: 350 V nominal rating suitable for extra‑high‑voltage applications within the LNX series voltage range of 350–550 V.
• Capacitance and Tolerance: 1.2 mF (1,200 µF) with ±20% tolerance at 120 Hz, 20°C, providing predictable energy storage for DC link and smoothing roles.
• Screw Terminal Package: Radial can with screw terminals for secure, low‑inductance connections in industrial assemblies and easy serviceability.
• Long Life Endurance: Rated for 20,000 hours at +85°C when operated at the specified ripple current, enabling extended maintenance intervals in continuous‑duty systems.
• High Ripple Current Capability: 4.2 A at 120 Hz and 5.88 A at 100 kHz, supporting applications with significant AC ripple stress.
• Wide Operating Temperature: −25°C to +85°C operating range suitable for many industrial environments.
• Leakage Current Limit: After 5 minutes at rated voltage, leakage ≤ 3√(C·V) µA or 5 mA whichever is smaller (measured at 20°C), for predictable stand‑by and leakage behavior.
• RoHS Compliant: Conforms to RoHS Directive (2011/65/EU,(EU)2015/863).
• Flame‑Retardant Electrolyte Option: LNX series offers flame‑retardant electrolyte types where specified.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for industrial DC power supplies, including applications feeding inverter stages.
• Inverter Circuitry: DC link and ripple management in inverter and motor‑drive power stages requiring high ripple handling and extra‑high voltage rating.
• High‑Ripple, High‑Voltage Power Conversion: Use where extended endurance under continuous ripple is needed—such as power conversion modules and rectifier smoothing.
• General‑Purpose Power Systems: Applications requiring polarized aluminum electrolytic capacitors with screw‑terminal mounting and robust mechanical connections.

Unique Advantages

• Proven Long Life: 20,000 hours endurance at +85°C when operated at rated ripple current reduces replacement frequency and lowers lifecycle maintenance effort.
• Engineered for High Ripple: Specified ripple current values at both 120 Hz and 100 kHz support designs with substantial AC stress across a range of switching frequencies.
• Secure Screw‑Terminal Connectivity: Screw terminals provide a durable, low‑resistance connection ideal for heavy‑current bus links and field servicing.
• Predictable Leakage Performance: Leakage current specified by the 3√(C·V) rule (or 5 mA cap) gives designers a clear bound for standby and fault analysis.
• RoHS‑Compliant Construction: Meets current RoHS requirements for use in regulated markets and installations.
• Series Flexibility: Part of the LNX family, which covers wide capacitance and voltage ranges, simplifying BOM choices when scaling designs.
