LNC2W332MSEGBB

The LNC2W332MSEGBB from Nichicon is a screw-terminal, aluminum electrolytic capacitor rated at 3300 µF and 450 V. Designed for industrial power electronics, this capacitor targets inverter and regenerative power circuits where high ripple handling, charge-discharge endurance and compact packaging are required.

As a member of the LNC series, it offers a smaller footprint with higher ripple-current capability compared with select LNX and LNK series parts, and is specified for continuous operation across a −40 °C to +85 °C temperature range.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) nominal capacitance with a rated voltage of 450 V for DC bus and inverter applications.
• Screw Terminal Package — Radial can with screw terminals for secure mechanical and electrical connections in power assemblies.
• High Ripple Current — Rated ripple current of 15.6 A at 120 Hz and 21.84 A at 100 kHz to handle high-frequency and high-amplitude ripple stress.
• Temperature Range — Operates from −40 °C to +85 °C for use in industrial environments.
• Load Life — Endurance specified as 5000 hours at 85 °C with rated DC bias plus rated ripple current applied, with performance limits on capacitance, tan δ and leakage current.
• Charge–Discharge Endurance — Rated for charge–discharge endurance testing (50 million cycles at room temperature per series specification), suitable for high-speed charge/discharge loading.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is specified as not more than 3√V (µA) or 5 mA, whichever is smaller (measured at 20 °C).
• Robust Insulation & Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.
• Polarized Construction — Polar aluminum electrolytic design for DC smoothing and energy buffering in power electronics.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk DC link and smoothing capacitor for inverter power stages, supporting high ripple and sustained DC bias at 450 V.
• AC Servomotor Regenerative Circuits — Suited for high-frequency regenerative voltages where rapid charge–discharge cycles and endurance are required.
• General Power Supplies — Filter and energy-storage capacitor for industrial power supplies that require long life at elevated temperature and continuous ripple loading.

Unique Advantages

• Higher Ripple Capability: Explicit ripple current ratings at both 120 Hz and 100 kHz enable designers to size capacitors for both low- and high-frequency ripple environments.
• Compact LNC Series Size: LNC-series parts offer smaller physical size with improved ripple performance compared with LNX and LNK series alternatives, helping conserve PCB/assembly space.
• Long Operational Life: 5000-hour load-life specification at 85 °C under rated ripple ensures predictable end-of-life behavior for industrial systems.
• High Charge–Discharge Endurance: Series-level charge–discharge testing supports applications with repeated high-speed energy transfer cycles.
• Electrical Safety Margins: Insulation resistance and voltage-proof specifications between terminal and bracket provide clear dielectric performance characteristics for system integration.
• Regulatory Compliance: RoHS compliance supports deployment in regulated industrial and commercial equipment.
