LNY2W103MSEJ

The LNY2W103MSEJ is an aluminum electrolytic capacitor in a screw-terminal radial can package, providing 10,000 µF capacitance at a 450 V rating. Designed for general-purpose use and suited for equipment downsizing, it delivers high bulk capacitance and high ripple-current capability in a compact, serviceable form factor.

Key value comes from its combination of high voltage, substantial ripple-current handling, and a 2,000-hour load-life rating at 85°C, making it appropriate for applications that demand reliable bulk energy storage and filtering at elevated operating temperatures.

Key Features

• Core Capacitance & Voltage — 10,000 µF rated capacitance with a 450 V DC rating and ±20% tolerance, providing significant bulk energy storage in a single component.
• High Ripple-Current Performance — Rated ripple current of 22.9 A at 120 Hz (low frequency) and 32.06 A at 10 kHz (high frequency), supporting applications with substantial ripple loads.
• Endurance & Reliability — Load life of 2,000 hours at 85°C with rated ripple current applied; leakage current specified at up to 5,000 µA and tan δ of 0.25.
• Temperature Range & Stability — Operates from −40°C to +85°C with an impedance ratio Z(−40°C)/Z(+20°C) of 12, supporting cold-start and elevated-temperature operation.
• Screw-Terminal Package — Radial can with screw terminals and M5 nominal bolt diameter for the φ90 size, enabling secure, low-resistance electrical and mechanical connections.
• Compact Large-Value Form — Physical dimensions φ90 × 155 L (L: 15.5 cm × D: 9.0 cm) deliver high capacitance density suitable for equipment downsizing.
• Regulatory — RoHS compliant.

Typical Applications

• Equipment Downsizing — High capacitance and 450 V rating in a screw-terminal can supports reductions in overall power subsystem footprint.
• General-Purpose Power Systems — Bulk energy storage and smoothing where a polarized, high-voltage electrolytic capacitor with high ripple capability is required.
• High-Ripple Environments — Systems requiring sustained ripple-current handling at both low and high frequencies benefit from the specified 22.9 A (120 Hz) and 32.06 A (10 kHz) ratings.

Unique Advantages

• High Voltage and High Capacitance in One Component: 10,000 µF at 450 V minimizes the number of parallel parts needed for high-voltage bulk capacitance.
• Designed for Continuous Ripple Loading: Rated ripple currents at 120 Hz and 10 kHz reduce thermal stress and extend subsystem stability under typical ripple conditions.
• Long Load Life at Elevated Temperature: 2,000-hour endurance at 85°C with ripple current applied offers predictable lifetime behavior for thermal environments up to the stated limit.
• Screw-Terminal Reliability: Robust screw terminals (M5 nominal for φ90) provide secure electrical and mechanical connections for serviceable installations.
• Wide Operating Temperature Range: −40°C to +85°C operation supports both cold-start and high-temperature use within the specified limits.
• Regulatory Compliance: RoHS compliance simplifies inclusion in assemblies subject to restricted-substance requirements.
