LNY2W332MSEFBB

The LNY2W332MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNY series, offering 3.3 mF (3300 µF) capacitance at a 450 V rating in a compact radial can with screw terminals. Designed for general-purpose use and suited for equipment downsizing, it combines high-voltage bulk capacitance with a mechanically robust screw-terminal package.

Key value propositions include high ripple-current capability, a rated operating range from –40 °C to +85 °C, and a demonstrated load life of 2000 hours at 85 °C under ripple-current conditions. The part is RoHS compliant.

Key Features

• Capacitance and Voltage: 3.3 mF (3300 µF) nominal capacitance with a 450 V rated voltage suitable for high-voltage bulk energy storage.
• Ripple-current capability: Rated ripple current of 11.1 A at 120 Hz and 15.54 A at 10 kHz to support circuits with significant AC ripple.
• Endurance at elevated temperature: Load life specified as 2000 hours with rated ripple current applied at 85 °C, with post-test limits defined for capacitance change, tan δ and leakage.
• Operating temperature range: –40 °C to +85 °C for use across common industrial ambient conditions.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C).
• Insulation and voltage proof: Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V 1 minute voltage proof between terminal and bracket.
• Mechanical and mounting: Radial can with screw terminals (M5 nominal bolt for φ51 diameter) for secure, serviceable connections; package dimension L: 17 × D: 5.1 cm (φ51 × 170 mm length).
• Polarized with ±20% tolerance: Polarized electrolytic capacitor with capacitance tolerance of ±20% (120 Hz, 20 °C).
• Marking and compliance: Black sleeve with white printing; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing where a 450 V, 3300 µF capacitor is required.
• Equipment downsizing projects: Provides high capacitance in a compact radial can format to support designs targeting reduced system volume.
• High-ripple environments: Suited to circuits that require sustained ripple current handling at elevated temperature, supported by the specified ripple-current ratings and 2000-hour load life at 85 °C.

Unique Advantages

• High-voltage, high-capacitance combination: 450 V rating paired with 3300 µF capacitance enables substantial bulk energy storage for high-voltage systems.
• Robust ripple-current performance: Defined ripple-current ratings at both 120 Hz and 10 kHz allow predictable thermal and life planning under AC-loading conditions.
• Long-term elevated-temperature endurance: 2000 hours of rated load-life at 85 °C gives a clear baseline for reliability planning in warm operating environments.
• Screw-terminal mounting: Provides secure, low-resistance connections and straightforward mechanical fastening for serviceable installations.
• Measured electrical integrity: Specified leakage, insulation resistance and voltage-proof performance help validate system safety and isolation requirements.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for end equipment.
