LNX2G182MSEFBB

The LNX2G182MSEFBB is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for high‑voltage power applications. With a rated capacitance of 1.8 mF (1800 µF) at 400 V and a long endurance specification, it targets industrial power supplies and inverter circuitry where high ripple tolerance and extended operational life are required.

Built for robust power filtering and DC‑link applications, this part combines high ripple current capability and a 20,000‑hour life at +85°C to support continuous operation in demanding environments while remaining RoHS compliant.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) capacitance at a 400 V rated voltage, suitable for high‑voltage energy storage and smoothing duties.
• Long Endurance: Endurance specified as 20,000 hours at +85°C when subjected to rated ripple current, supporting extended service life in continuous‑duty applications.
• High Ripple Capability: Designed for high ripple currents with specified ripple ratings of 6 A at 120 Hz and 8.4 A at 100 kHz, enabling effective filtering under heavy load conditions.
• Temperature Range & Stability: Operating temperature range of −25°C to +85°C with an impedance ratio Z(−25°C)/Z(+20°C) of 8, supporting stable performance across typical industrial ambient variations.
• Low Leakage Specification: Leakage current after 5 minutes at 20°C is limited to not more than 3√(C·V) µA or 5 mA, whichever is smaller, allowing predictable standby and charged‑state behavior.
• Screw Terminal Mechanical Package: Radial can with screw terminals; the φ51 size uses M5‑nominal bolt terminals (terminal pitch W = 22.0 mm), providing secure power connections for high current paths.
• Tolerance & Polarization: Capacitance tolerance of −20% to +20% and polarized construction—suitable for DC applications where polarity is defined.
• Compliance: RoHS compliant, meeting current restricted‑substance requirements.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in industrial AC/DC and DC/DC power supplies where sustained ripple handling and long life are required.
• Inverter Circuitry: DC‑link and filtering duties in inverter systems, leveraging high ripple current capacity and a 400 V rating.
• General‑Purpose High‑Voltage Filtering: General purpose power filtering in high‑voltage circuits that require robust screw‑terminal connections and predictable leakage characteristics.

Unique Advantages

• Extended Operational Life: 20,000 hours at +85°C under rated ripple current—reduces maintenance frequency and improves system uptime in continuous‑duty installations.
• High Ripple Handling: Explicit ripple current ratings at both low and high frequencies (6 A @120 Hz, 8.4 A @100 kHz) enable confident specification for a wide range of switching power topologies.
• Robust Screw‑Terminal Interface: M5 nominal bolt terminals (for φ51 size) provide mechanically secure, low‑impedance connections for high current paths and easy field wiring.
• Predictable Leakage Behavior: Defined leakage current limit (3√CV µA or 5 mA after 5 minutes at 20°C) assists design margining for charged circuits and safety considerations.
• Wide Operating Temperature Span: −25°C to +85°C operation supports installation in varied industrial environments without sacrificing performance.
• Regulatory Compliance: RoHS compliant construction supports deployment in regulated markets and simplifies environmental compliance.
