LNX2J182MSEH

The LNX2J182MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, rated at 1.8 mF (1800 µF) and 630 V. It is a polarized, radial can-style capacitor designed for high-ripple, extra-high-voltage applications, with a construction optimized for secure screw-terminal mounting.

Targeted for industrial power conversion, the part is suited for inverter circuitry and other industrial power supplies where high ripple current, long operational life at elevated temperature, and reliable high-voltage performance are required.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) capacitance with a 630 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Screw-Terminal Package — Radial, can-style package with screw terminals for robust, low-resistance connections in power assemblies.
• High Ripple Capability — Rated ripple current: 9.6 A at 120 Hz and 13.44 A at 100 kHz, supporting demanding AC/heavily loaded DC environments.
• Long Life at Elevated Temperature — Specified for long-life operation under rated ripple current at +85°C (20,000 hours in the LNX series endurance specification).
• Operating Temperature Range — Specified to operate from −25°C to +85°C for a wide range of industrial ambient conditions.
• Leakage Current Specification — After 5 minutes' application of rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (C: µF, V: V).
• Low-Temperature Stability — Impedance ratio Z(−25°C)/Z(+20°C) ≤ 8, maintaining performance in colder conditions.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitance in high-voltage industrial power supplies requiring durable, high-capacitance components.
• Inverter Circuitry — DC-link and energy-storage capacitor for inverter stages subjected to high ripple currents and elevated temperature operation.
• Extra‑High‑Voltage Power Conversion — Applications that require capacitors rated for extra-high voltage with extended ripple life.

Unique Advantages

• High Voltage Handling: 630 V rating supports extra-high-voltage designs without series stacking complexity.
• Robust Ripple Performance: High rated ripple currents (9.6 A at 120 Hz; 13.44 A at 100 kHz) reduce heating and extend service life under heavy AC stress.
• Long Endurance at Elevated Temperature: Engineered for extended operation under rated ripple at +85°C (LNX series endurance specification), enabling predictable lifecycle planning.
• Screw-Terminal Reliability: Mechanical screw terminals provide secure mounting and low-resistance connections suitable for high-current bus assemblies.
• Measured Low-Temperature Behavior: Impedance controlled to Z(−25°C)/Z(+20°C) ≤ 8 for retained performance across the specified temperature range.
• Standards-Conscious Design: Leakage current and endurance characteristics are specified per the LNX series datasheet and the product is RoHS compliant.
