LNY2V332MSEG

The LNY2V332MSEG is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNY series designed for general‑purpose power applications. It provides high capacitance (3.3 mF) at a 350 V rating with a radial can and screw terminal mounting to simplify connections in power assemblies.

Its construction and specifications target equipment downsizing and robust ripple handling, offering a long load life at elevated temperature and RoHS compliance for environmentally conscious designs.

Key Features

• Capacitance & voltage — 3300 µF (3.3 mF) nominal capacitance with a 350 V rated voltage; tolerance ±20% (measured at 120 Hz, 20°C).
• Screw terminal mounting — Radial can with screw terminals (terminal pitch and bolt size per φ63.5 dimensions, nominal bolt M5) for secure, low‑impedance connections in power equipment.
• High ripple handling — Low‑frequency ripple current 13.1 A (120 Hz) and high‑frequency ripple current 18.34 A (10 kHz) to support demanding power supply ripple loads.
• Endurance — Rated for 2000 hours at 85°C while subjected to rated voltage plus ripple current (endurance specified in datasheet).
• Temperature range — Operating from −40°C to +85°C for broad environmental tolerance.
• Leakage and dissipation — Specified leakage current 3220 µA; tangent of loss angle (tan δ) 0.25 measured at 20°C, 120 Hz.
• Insulation & voltage proof — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V for 1 minute shows no abnormality between terminal and bracket.
• Compliance — RoHS‑compliant per the series documentation.
• Physical size & packaging — φ63.5 × 75 L (mm) radial can; supplied in cardboard packing; brackets supplied separately per series guidelines.

Typical Applications

• Industrial power supplies — Bulk and smoothing capacitor for high‑voltage supplies where 350 V rated capacitance and high ripple handling are required.
• Energy conversion and inverters — Energy storage and ripple filtering in systems that operate across −40°C to +85°C and require sustained endurance at elevated temperature.
• Motor drives and UPS systems — DC link and filtering uses that benefit from the capacitor’s high ripple current capability and screw‑terminal connections for robust wiring.
• Equipment downsizing projects — Applications aiming to reduce board or enclosure size while maintaining required bulk capacitance, as indicated in the LNY series guidance.

Unique Advantages

• High voltage and high capacitance in a single part — 350 V rating with 3300 µF nominal capacitance provides necessary energy storage for high‑voltage power designs without combining multiple smaller capacitors.
• Screw‑terminal convenience — Radial can with screw terminals and M5 bolt compatibility enables secure mechanical and electrical connections for high current paths.
• Designed for sustained ripple — Specified ripple currents of 13.1 A (120 Hz) and 18.34 A (10 kHz) support continuous ripple loading in power stages.
• Temperature and endurance validated — Rated operation from −40°C to +85°C and endurance tested for 2000 hours at 85°C under rated conditions support predictable lifetime planning.
• Measurable electrical characteristics — Tangent of loss angle (tan δ) and leakage current are specified (tan δ = 0.25 at 20°C, 120 Hz; leakage 3220 µA), enabling accurate thermal and loss budgeting in designs.
• RoHS compliance — Conforms to RoHS directives for regulated substance requirements in commercial and industrial products.
