LNY2G183MSEJBN

The LNY2G183MSEJBN is an aluminum electrolytic capacitor in a screw-terminal can designed for high-capacitance, high-voltage general-purpose applications. It delivers 18,000 µF at 400 V with a screw-terminal radial package intended for robust power-system connections and equipment downsizing.

Engineered for continuous operation up to 85°C, this part combines high bulk capacitance, defined ripple handling and a 2,000-hour load life at 85°C to support demanding power-electronics designs and industrial power systems.

Key Features

• High Capacitance: 18,000 µF rated capacitance for substantial bulk energy storage and smoothing in power rails.
• High Voltage Rating: 400 V rated voltage suitable for high-voltage power supplies and DC-link applications.
• Screw Terminal Mounting: Screw terminal radial can package for secure, low-impedance terminations in heavy-current installations.
• Temperature and Lifetime: Rated operating range −40°C to +85°C with a rated load life of 2,000 hours at 85°C.
• Ripple Current Capability: 30.6 A at 120 Hz and 42.84 A at 10 kHz for effective AC ripple handling under specified conditions.
• Leakage and Loss Characteristics: Specified leakage current up to 5,000 µA and tangent of loss angle (tan δ) of 0.25 to characterize dissipation and self‑loss.
• Packaging and Production: Supplied in cardboard packing; produced for mass production availability.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing in industrial power electronics and high-voltage power supplies.
• DC-link and intermediate storage: Use where high-voltage, high-capacitance components are required to stabilize DC buses and absorb ripple.
• Equipment downsizing initiatives: Series design attributes support higher capacitance density to help reduce overall system volume.

Unique Advantages

• Substantial energy density: 18,000 µF at 400 V provides large charge storage per component, reducing the need for multiple smaller capacitors.
• Robust termination: Screw-terminal construction offers durable, low-resistance connections suited to higher current installations and serviceability.
• Defined ripple performance: Specified ripple currents at both 120 Hz and 10 kHz enable predictable thermal and electrical design margins.
• Wide temperature tolerance: Rated −40°C to +85°C to accommodate a broad range of industrial operating environments.
• Proven endurance: 2,000-hour rated life at 85°C with defined post-endurance electrical limits for reliable long-term operation under rated ripple and voltage.
• Series-level reliability details: Series documentation includes leakage current and tan δ specifications and shelf-life endurance guidance for engineering validation.
