LNC2W103MSEJ

The LNC2W103MSEJ is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNC series, rated 10,000 µF at 450 V. It delivers high ripple current handling in a compact can‑style, screw‑terminal package suited for industrial power systems.

Designed for applications such as inverter circuitry and regenerative high‑frequency voltages, this polarized radial can provides durable operation across a −40°C to +85°C range with a rated load life of 5,000 hours at 85°C.

Key Features

• High Capacitance: 10,000 µF nominal capacitance for bulk energy storage and smoothing in power converter designs.
• High Voltage Rating: Rated for 450 V operation to support medium‑voltage inverter and industrial power supply rails.
• Screw Terminal Mounting: Robust screw‑terminal radial can package for secure electrical and mechanical connections in high‑current systems.
• High Ripple Current Capability: Handles 34.1 A at 120 Hz (low frequency) and 47.74 A at 100 kHz (high frequency), enabling effective ripple suppression across a wide frequency range.
• Endurance and Reliability: Load life of 5,000 hours at 85°C with defined post‑test limits on capacitance change, tan δ and leakage current.
• Operating Range and Tolerance: Operating temperature −40°C to +85°C with capacitance tolerance ±20% (at 120 Hz, 20°C).
• Leakage Current: Specified leakage current up to 5,000 µA (measured conditions per product data).
• Compact Form Factor: φ90 × 155 mm can size (radial can with screw terminals) to balance high capacitance and space efficiency.
• RoHS Compliant: Conforms to RoHS requirements as stated for the LNC series.

Typical Applications

• Industrial Inverter Power Supplies: Bulk smoothing and ripple suppression on DC link and intermediate circuits for inverters.
• AC Servomotor Regeneration: Energy buffering and high‑frequency regenerative voltage support in motor drive systems.
• High‑Frequency Charge/Discharge Systems: Suitable where rapid charge/discharge and high ripple currents are required.
• General Purpose Power Electronics: Bulk energy storage and decoupling in medium‑voltage industrial power equipment.

Unique Advantages

• High ripple current handling: Measured ripple ratings at both 120 Hz and 100 kHz enable reliable performance across low and high frequency regimes.
• Designed for inverter/regenerative environments: Series characteristics explicitly target industrial inverter and regenerative voltage use cases.
• Durable long life: 5,000‑hour rated load life at 85°C supports extended operation under rated loading conditions.
• Secure screw‑terminal connections: Screw terminals provide robust high‑current terminations for industrial assemblies.
• High voltage and large capacitance in a compact can: 10,000 µF at 450 V in a φ90 × 155 mm package for high‑energy density in constrained footprints.
• Temperature range and tolerance: Wide −40°C to +85°C operating range and ±20% capacitance tolerance for predictable behavior in varied environments.
