LNY2W822MSEH

The LNY2W822MSEH is an aluminum electrolytic, screw-terminal capacitor supplying 8.2 mF of capacitance at a 450 V rating. Designed as a high-capacitance, screw-terminal radial can, it is targeted for general-purpose power equipment and applications that require robust bulk energy storage and high ripple handling in a compact cylinder (φ76.2 × 170 mm).

Key value propositions include high rated voltage, significant ripple-current capability at both low and high frequencies, a 2000-hour endurance at 85°C, and RoHS compliance—features useful for equipment downsizing and reliable power-system designs.

Key Features

• Capacitance & Voltage — 8.2 mF (8,200 µF) rated at 450 V for high-voltage bulk capacitance requirements.
• Screw Terminal Package — Radial can with screw terminals (M5 nominal bolt for φ76.2) for robust, low-impedance connections in power assemblies.
• High Ripple Current — 20.1 A at 120 Hz (low frequency) and 28.14 A at 10 kHz (high frequency) to handle substantial AC ripple in power supply and DC-link circuits.
• Loss Characteristics — tan δ (DF) = 0.25 (measurement condition: 120 Hz at 20°C) to characterize dissipation behavior.
• Endurance & Temperature — Rated for 2000 hours at 85°C with operating temperature range from −40°C to +85°C.
• Leakage Current — Specified leakage current of 5000 µA for sizing pre-charge and bleed considerations.
• Insulation & Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality (per series datasheet).
• Compliance & Packing — RoHS compliant; supplied in cardboard packing and available for mass production supply.

Typical Applications

• General-purpose power equipment — Provides high-capacitance energy storage and smoothing where 450 V rated bulk capacitance is required.
• Power racks and modular assemblies — Screw terminal mounting and M5 bolt-compatible terminals enable secure connections for large power modules and assemblies.
• Equipment downsizing efforts — Higher capacitance in the LNY series helps reduce component count and supports more compact power designs.

Unique Advantages

• High-voltage bulk capacitance: 8.2 mF at 450 V provides substantial energy storage in a single component, simplifying designs that need large capacitance at high voltage.
• Robust ripple handling: Rated ripple currents of 20.1 A (120 Hz) and 28.14 A (10 kHz) reduce thermal stress and allow sustained ripple performance in demanding power environments.
• Thermal endurance: 2000 hours at 85°C demonstrates longevity under continuous ripple loading at elevated temperature.
• Secure electrical connections: Screw-terminal radial can and M5 terminal compatibility enable reliable mechanical and electrical mounting in power systems.
• Measurable dissipation: tan δ = 0.25 (120 Hz, 20°C) gives designers a clear parameter for loss and heating assessments.
• Regulatory and production ready: RoHS compliant and supplied in cardboard packing for mass-production deployment and logistics.
