LNT2W331MSEC

The LNT2W331MSEC is a polarized aluminum electrolytic capacitor in a radial can with screw terminals, designed for general-purpose power electronics requiring high-voltage capability and robust mounting. It delivers 330 µF at a 450 V rating and is built for sustained operation up to 105°C.

Engineered for applications that demand bulk energy storage, DC link smoothing and high ripple endurance, this part combines a high working voltage, industry-standard capacitance tolerance, and RoHS compliance for use in industrial and power conversion designs.

Key Features

• Voltage and Capacitance — 330 µF nominal capacitance rated at 450 V for high-voltage power applications.
• High Ripple Current — Specified ripple handling of 2.4 A at 120 Hz and 3.36 A at 100 kHz to support demanding AC ripple loads.
• High-Temperature Endurance — Rated for operation from −25 °C to +105 °C with a load life specified at 5,000 hours at 105 °C.
• Screw-Terminal Mounting — Radial can with screw terminals for secure electrical and mechanical connections in power assemblies.
• Polarized Construction — Designed as a polarized aluminum electrolytic for DC bulk storage and smoothing functions.
• Capacitance Tolerance & Size — ±20% tolerance at 120 Hz, 20 °C; physical size listed as L: 10 × D: 3.5 cm for layout planning.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and energy storage in high-voltage DC supplies where 450 V rating and sustained ripple handling are required.
• DC Link and Inverter Circuits — DC link capacitors for power conversion stages benefiting from high ripple current capability and 105 °C endurance.
• Motor Drives and Drives Electronics — Energy buffering and transient absorption in drive controllers that require secure screw-terminal mounting and reliable high-voltage performance.

Unique Advantages

• High working voltage: 450 V rating enables use in higher-voltage power and conversion topologies without series stacking.
• Designed for ripple stress: Specified ripple currents at both low and high frequencies (2.4 A at 120 Hz, 3.36 A at 100 kHz) reduce thermal stress under common power-electronic waveforms.
• Long-term high-temperature life: 5,000 hours at 105 °C provides predictable endurance for elevated-temperature environments.
• Robust mechanical connection: Screw-terminal radial can package simplifies heavy-current wiring and provides secure mounting in industrial assemblies.
• Clear sizing and tolerance: Standard ±20% tolerance and provided physical dimensions (L: 10 × D: 3.5 cm) help with BOM and enclosure planning.
• Regulatory compliance: RoHS status helps align with environmental and manufacturing requirements.
