LNX2W332MSEG

The LNX2W332MSEG is a screw-terminal aluminum electrolytic capacitor designed for high-voltage, high-ripple power applications. It provides 3300 µF capacitance at a 450 V rating in a robust radial can with M5 screw terminals, targeting industrial power supplies and inverter circuitry.

Engineered for sustained performance, this part combines high ripple-handling capability, long endurance, and polarized electrolytic construction to support bulk energy storage and smoothing functions in demanding systems.

Key Features

• Electrical Performance — 3.3 mF (3300 µF) capacitance at 450 V with ±20% tolerance, suitable for high-voltage energy storage and smoothing.
• High Ripple Current — Rated for 10 A low-frequency ripple current at 120 Hz and 14 A high-frequency ripple current at 100 kHz, enabling effective handling of both mains-frequency and switching ripple.
• Reliability & Endurance — Rated life of 20,000 hours at +85°C when subjected to standard ripple current; designed for long-term operation under rated conditions.
• Leakage and Dissipation — Specified leakage current of 3650 µA and tan δ (DF) of 0.2 at 20°C and 120 Hz, providing defined loss and leakage behavior for design validation.
• Mechanical & Mounting — Radial can with screw terminals (M5), size φ63.5 × 150L (dimensions L: 15 cm × D: 6.35 cm), suitable for secure bolted connections in power assemblies.
• Operating Conditions — Polarized capacitor with an operating temperature range of −25°C to +85°C, covering typical industrial ambient environments.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high-voltage industrial supplies, benefiting from the 450 V rating and high ripple-current capability.
• Inverter and Motor Drive Circuits — DC-link and filter capacitor for inverter stages where sustained ripple handling and long endurance at elevated temperatures are required.
• Switch-Mode Power Supplies (SMPS) — Filtering and energy buffering in high-voltage SMPS designs that generate both low- and high-frequency ripple components.
• General Purpose High-Voltage Systems — Applications that require polarized high-capacitance components with screw-terminal mounting for secure electrical and mechanical connections.

Unique Advantages

• High ripple-handling capability: 10 A at 120 Hz and 14 A at 100 kHz allow the capacitor to manage both mains and switching ripple without frequent replacement.
• Long operational life: 20,000 hours endurance at +85°C under rated ripple current supports extended maintenance intervals in continuous-duty systems.
• Robust screw-terminal mounting: M5 screw terminals and a φ63.5 × 150L can provide secure electrical and mechanical connections for heavy-current applications.
• Clear electrical characterization: Specified tan δ (0.2 at 20°C, 120 Hz) and leakage current figures support accurate thermal and reliability modeling.
• RoHS compliance: Meets environmental regulatory requirements for lead-free manufacturing and procurement.
• Series-level safety features: Series documentation notes availability of flame-retardant electrolyte types, supporting safer selection where needed.
