LNY2W682MSEH

The LNY2W682MSEH is a screw-terminal aluminum electrolytic capacitor offering 6.8 mF capacitance at a 450 V rating in a compact radial can package (φ76.2 × 150L). It is designed as a general-purpose high-capacitance solution for equipment that benefits from increased energy density and convenient screw-terminal connections.

With high ripple-current capability, a −40°C to 85°C operating range, and a 2000-hour endurance at 85°C under rated ripple conditions, this part targets applications that require robust bulk capacitance and reliable long-term performance in demanding power environments.

Key Features

• Core Electrical — 6.8 mF (6800 µF) nominal capacitance with ±20% tolerance (120 Hz, 20°C) and tan δ = 0.25 (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 450 V operation for high-voltage bulk energy storage in general-purpose equipment.
• Ripple Current Handling — Supports 19.6 A at 120 Hz and 27.44 A at 10 kHz, enabling sustained AC ripple performance for power electronic systems.
• Leakage Current — Specified leakage current up to 5000 µA after application of rated voltage (product specification).
• Reliability & Endurance — Load-life endurance of 2000 hours at 85°C with rated ripple, and a shelf-life test condition listed in the datasheet; designed to meet endurance requirements after restoration to 20°C.
• Temperature Range — Operating from −40°C to +85°C to cover a wide range of ambient conditions.
• Mechanical & Mounting — Radial can with screw terminals (φ76.2 case); terminal and bracket insulation resistance >100 MΩ at DC 500 V and AC 2500 V voltage proof between terminal and bracket as specified in the datasheet. Terminal bolt nominal diameter for this case size is M5.
• Packaging & Compliance — Cardboard packing and RoHS compliant.

Typical Applications

• General-purpose equipment — Provides high-voltage bulk capacitance for general-purpose systems requiring robust energy storage and screw-terminal connections.
• Equipment downsizing — Higher capacitance in a screw-terminal radial can form factor, suited to designs that aim to reduce component count or board area.
• High-ripple environments — Applicable where sustained ripple current is required, given the rated 19.6 A (120 Hz) and 27.44 A (10 kHz) ripple capacities.

Unique Advantages

• High-voltage, high-capacitance combination: 6.8 mF at 450 V supplies substantial bulk energy in a single component, simplifying designs that need high DC bus capacitance.
• Strong ripple-current capability: Rated ripple currents at both low and high frequencies support demanding AC ripple conditions without frequent replacement.
• Endurance at elevated temperature: 2000-hour rated life at 85°C under specified ripple conditions provides predictable aging and replacement planning.
• Wide operating range: −40°C to +85°C operating window allows deployment across a broad range of ambient environments.
• Screw-terminal convenience: Radial can with screw terminals and M5 bolt compatibility enables secure, low-resistance connections for power assemblies.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance.
