LNX2J272MSEJBB

The LNX2J272MSEJBB is a screw-terminal aluminum electrolytic capacitor designed for extra‑high voltage, high‑ripple applications. It provides 2.7 mF (2700 µF) capacitance at a 630 V rating in a radial can with screw terminals, targeting industrial power electronics such as inverter circuitry and other power supply systems.

This capacitor is built for high ripple endurance and extended operational life at elevated temperature, while offering polarity, ±20% capacitance tolerance, and RoHS compliance for regulated environments.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 630 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High ripple current capability — Rated ripple current of 12.6 A at 120 Hz and 17.64 A at 100 kHz to support heavy AC ripple in power conversion circuits.
• Long endurance at elevated temperature — Engineered for long life under rated ripple current at +85°C, with series documentation indicating long‑life performance for 20,000 hours at +85°C when operated under rated conditions.
• Operating temperature range — Specified for −25°C to +85°C operation to suit a wide range of industrial ambient conditions.
• Package & mounting — Radial can with screw terminals for secure, low‑resistance connections in power modules and assemblies.
• Leakage current specification — After 5 minutes of rated voltage application, leakage current is limited to 3√(C·V) μA or 5 mA, whichever is smaller (per series specification).
• Flame retardant electrolyte option — Flame retardant electrolyte is available for types in this series to address safety considerations.
• Regulatory compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical size — Package dimensions listed as L: 15 × D: 9 cm for board or chassis planning.

Typical Applications

• Industrial power supplies — Used in high‑voltage sections of industrial supplies where sustained ripple handling and reliability at +85°C are required.
• Inverter circuitry — Suited for inverter DC link and filtering applications that demand extra‑high voltage ratings and high ripple current capability.
• High‑voltage power conversion — Applicable in converters and power-conditioning equipment that operate at elevated voltages and require robust smoothing capacitors.
• General purpose power systems — Useful where a high‑capacity, screw‑terminal aluminum electrolytic with long life and RoHS compliance is needed.

Unique Advantages

• Extra‑high voltage rating: 630 V capability enables use in higher‑voltage power stages without series stacking of capacitors.
• High ripple endurance: Specified ripple currents at both 120 Hz and 100 kHz support heavy ripple environments and improve system stability.
• Long operational life at elevated temperature: Series design supports extended life under rated ripple current at +85°C, helping reduce maintenance and replacement cycles.
• Screw terminal packaging: Radial can with screw terminals provides robust electrical and mechanical connections for power assemblies.
• Safety and regulatory fit: Flame retardant electrolyte options and RoHS compliance support regulatory and safety considerations in industrial designs.
