LNY2W182MSEF

The LNY2W182MSEF is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNY series, offering 1.8 mF (1800 µF) capacitance at a 450 V rated voltage. Designed as a high-capacitance, screw-terminal radial can, it targets general-purpose power applications that require high-voltage filtering and energy buffering.

Key value comes from its high ripple-current capability, long load life at elevated temperature, and a form factor intended to support equipment downsizing while providing reliable DC performance across a −40°C to 85°C operating range.

Key Features

• High Capacitance and Voltage: 1.8 mF (1800 µF) rated at 450 V for high-voltage energy storage and smoothing.
• Screw Terminal Mounting: Radial can with screw terminals (M5 nominal bolt for φ51 size) for secure, low-impedance connections suitable for high-current installations.
• High Ripple Current: Rated ripple current of 7.9 A at 120 Hz and 11.06 A at 10 kHz to support heavy AC ripple loads and switching power environments.
• Endurance and Reliability: Load life of 2000 hours at 85°C when rated ripple is applied, supporting sustained high-temperature operation.
• Leakage and Loss Characteristics: Specified leakage current of 2700 µA and tan δ of 0.25 (measurement basis at 120 Hz, 20°C), enabling predictable leakage and dissipation planning.
• Operating Range and Tolerance: Wide operating temperature range of −40°C to 85°C with capacitance tolerance of ±20% (120 Hz, 20°C).
• RoHS Compliant: Complies with RoHS requirements for restricted substances.
• Compact High-Capacitance Form: Physical size φ51 × 95 mm (L: 95 mm × D: 51 mm) offers a high-capacitance solution in a relatively compact radial screw-terminal package to assist with equipment downsizing.

Typical Applications

• Power Supply Filtering: High-voltage smoothing and bulk capacitance for switching and linear power supplies where 450 V rating and high ripple capability are required.
• Industrial Power Electronics: Energy buffering and ripple handling in industrial converters and inverters that operate across −40°C to 85°C.
• DC Link and Energy Storage: Bulk DC-link capacitance in high-voltage circuits benefiting from the 1.8 mF capacity and elevated ripple current ratings.

Unique Advantages

• High-Voltage, High-Capacity Combination: 1.8 mF at 450 V provides significant stored energy per component, reducing the need for multiple smaller capacitors.
• Robust Ripple Handling: Dual-specified ripple current ratings (7.9 A at 120 Hz, 11.06 A at 10 kHz) help designers account for both low-frequency and high-frequency ripple in power systems.
• Screw-Terminal Reliability: Screw terminal and M5 fastening enable secure mechanical and electrical connections for high-current or vibration-prone environments.
• Designed for Elevated-Temperature Endurance: 2000-hour load-life at 85°C supports sustained performance in hotter operating environments and long-term deployments.
• Predictable Electrical Behavior: Specified tan δ and leakage current figures allow accurate thermal and leakage budgeting in designs.
• RoHS Compliance: Meets environmental substance restrictions to support regulatory and sourcing requirements.
