LNX2W272MSEG

The LNX2W272MSEG is an aluminum electrolytic, screw-terminal capacitor from Nichicon's LNX series, offering 2.7 mF (2700 µF) capacitance at a 450 V rating. Engineered for industrial power electronics, it targets inverter circuitry and other extra‑high‑voltage applications where sustained ripple handling and long life are required.

With high ripple current capacity, screw‑terminal construction for secure connections, and a long endurance rating at elevated temperature, this component is intended for designs that need reliable power filtering and energy storage under demanding conditions. It is RoHS compliant and an option with flame‑retardant electrolyte is available in the series.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Screw Terminal Packaging — Radial can with screw terminals for robust, high-current connections and straightforward mechanical mounting.
• High Ripple Capability — Rated ripple current of 8.6 A at 120 Hz and 12.04 A at 100 kHz to support heavy AC ripple environments common in inverter and industrial power supplies.
• Long Endurance — Designed for 20,000 hours of operation at +85°C under rated ripple current, with defined post‑test limits for capacitance, tan δ and leakage current.
• Operating Temperature Range — Specified for −25°C to +85°C operation to cover a broad set of industrial ambient conditions.
• Leakage and Low‑Temperature Stability — Leakage current after 5 minutes is limited to 3√CV µA or 5 mA (whichever is smaller); impedance stability to −25°C is specified by the series.
• Compliance & Safety Options — RoHS compliant; flame‑retardant electrolyte types are available within the LNX series.
• Series Scalability — The LNX family covers rated voltages from 350 V to 550 V and capacitances from 1000 µF to 27000 µF, with extended sizes up to φ100 = 250L for broader design flexibility.

Typical Applications

• Industrial Power Supplies — Used in inverter circuitry and power delivery modules where high voltage and continuous ripple duty are present.
• Extra‑High‑Voltage Power Systems — Applicable in systems requiring nominal voltages in the 350–550 V range as provided across the LNX series.
• General Purpose Power Electronics — Employed where long life, high ripple capability and screw‑terminal mounting simplify integration and maintenance.

Unique Advantages

• High ripple handling — Specified ripple currents at both low and high frequencies reduce heating and extend service life in demanding AC environments.
• Predictable endurance — 20,000‑hour rating at +85°C under rated ripple current supports planned maintenance cycles and lifecycle forecasting.
• Secure electrical and mechanical connections — Screw‑terminal design enables reliable high‑current terminations and easier field replacement.
• Regulatory compliance and safety options — RoHS compliance and the availability of flame‑retardant electrolyte options help meet environmental and safety considerations.
• Design scalability — LNX series range of voltages and capacitances allows designers to scale capacitance and voltage across related designs without changing capacitor families.
