LNX2J182MSEHBB

The LNX2J182MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series designed for high-voltage, high-ripple applications. It is a polarized, radial can package intended for industrial power systems, specifically suited to inverter circuitry and other extra‑high voltage uses. The device delivers high ripple-current capability and extended operational life under rated ripple at elevated temperature.

Key Features

• High voltage rating: 630 V rated voltage for extra-high voltage applications.
• Large capacitance: 1.8 mF (1800 µF) with ±20% tolerance, providing substantial energy storage and filtering.
• Screw terminal mounting: Radial can with screw terminals for secure, low-impedance connections in high-current systems.
• High ripple current capability: Rated ripple currents of 9.6 A at 120 Hz and 13.44 A at 100 kHz permit robust filtering under heavy AC ripple loading.
• Long life at elevated temperature: Specified for long-life operation with rated ripple current at +85°C (long life performance up to 20,000 hours under rated ripple conditions as described by the series).
• Operating temperature range: −25 °C to +85 °C to cover typical industrial environments.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller.
• Safety and compliance: Flame-retardant electrolyte types available; RoHS compliant (2011/65/EU, (EU)2015/863).
• Mechanical dimensions: Body size L: 15 × D: 7.62 cm with maximum seated height 5.906 inches (as specified).

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for high-voltage power conversion and distribution in industrial equipment.
• Inverter circuitry — DC link and filtering where high voltage and high ripple current capability are required.
• Extra‑high voltage systems — Energy buffering and ripple attenuation in systems that demand 630 V rated components.
• General purpose power electronics — Applications needing polarized, high-capacitance screw-terminal capacitors for robust electrical connections.

Unique Advantages

• Designed for high ripple environments: Specified ripple currents at both low and high frequencies reduce the need for multiple parallel components when filtering heavy AC ripple.
• Long operational life at temperature: Long-life specification under rated ripple at +85 °C supports reliable operation in continuous-duty industrial systems.
• Screw-terminal robustness: Screw terminals provide secure mechanical and electrical connections for high-current bus work and easier field installation.
• High-voltage capability: 630 V rating enables use in extra‑high voltage designs without resorting to series stacking of lower-voltage parts.
• Regulatory compliance and safety options: RoHS compliance and availability of flame-retardant electrolyte types support regulatory and safety requirements.
