LNX2V273MSEKBN

The LNX2V273MSEKBN is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for extra‑high voltage and high‑ripple applications. It delivers 27,000 µF capacitance at a 350 V rating in a φ100 × 250L package and is intended for industrial power electronics where sustained ripple handling and long operational life are required.

Part of Nichicon's LNX series, this screw‑terminal type is suited for use in industrial power supplies and inverter circuitry and offers a long endurance specification for continuous operation at elevated temperature.

Key Features

• Capacitance & Voltage — 27,000 µF nominal capacitance with a rated voltage of 350 V and ±20% tolerance, providing substantial bulk energy storage for high‑voltage systems.
• High Ripple Current Capability — Rated ripple current of 42 A at 120 Hz and 58.8 A at 100 kHz, enabling effective smoothing under heavy AC ripple conditions.
• Long Life / Endurance — Specified for 20,000 hours of rated ripple current operation at +85°C; endurance verified after standard ripple current exposure per LNX series specifications.
• Package & Mounting — Radial can with screw terminals (φ100 size uses M8 nominal bolt), designed for secure mechanical and electrical connections in high‑power assemblies.
• Temperature Performance — Operating temperature range −25°C to +85°C with low‑temperature impedance stability (Z(−25°C)/Z(+20°C) ≤ 8 for the series).
• Leakage Current Spec — After 5 minutes’ application of rated voltage, leakage current is limited to ≤ 3√(C·V) µA or 5 mA, whichever is smaller, per the series specification.
• Safety & Materials — Flame‑retardant electrolyte option available; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for inverter circuitry and high‑voltage industrial power modules.
• Power Conversion Systems — Suitable where high DC link capacitance and substantial ripple handling are required.
• General Purpose High‑Voltage Filtering — Use in systems that require long life under continuous ripple and elevated temperature operating conditions.

Unique Advantages

• High energy density at extra‑high voltage: 27,000 µF at 350 V provides significant bulk capacitance in a single radial can package, reducing the need for parallel parts.
• Designed for sustained ripple: Rated ripple currents of 42 A (120 Hz) and 58.8 A (100 kHz) support continuous heavy AC ripple environments common to power electronics.
• Long operational life at elevated temperature: Endurance specified for 20,000 hours at +85°C under rated ripple current, supporting long maintenance intervals.
• Robust screw‑terminal mounting: Screw terminals and φ100 can diameter with M8 nominal bolt provision enable secure mechanical fastening and reliable current connections.
• Low‑temperature impedance stability: Impedance ratio (Z(−25°C)/Z(+20°C)) ≤ 8 helps maintain performance across the specified operating range.
• Regulatory and material considerations: RoHS compliant and offered with a flame‑retardant electrolyte option for safety‑minded designs.
