Overview of LNC2W392MSEGBN – Aluminum Electrolytic Screw-Terminal Capacitor, 3900 µF, 450 V

The LNC2W392MSEGBN is an aluminum electrolytic, screw-terminal capacitor designed for high-power industrial applications. It delivers 3.9 mF (3900 µF) capacitance at a 450 V rating in a radial can with screw terminals for secure power connections.

Engineered for inverter and regenerative circuits, this part provides high ripple-current capability and a 5000-hour load life at 85°C, making it suitable for industrial power supplies, AC servomotor drives, and general inverter systems where high-frequency charge–discharge performance and reliability are required. The product is RoHS compliant.

Key Features

  • Capacitance & Rated Voltage — 3.9 mF (3900 µF) rated at 450 V for bulk energy storage in high-voltage power circuits.
  • Screw Terminal Mounting — Radial can with screw terminals provides robust, low-impedance connections for power and regenerative circuits.
  • High Ripple-Current Performance — Specified ripple current: 17.3 A at 120 Hz and 24.22 A at 100 kHz, supporting high-frequency and high-rate charge–discharge operation.
  • Endurance / Load Life — Rated for 5000 hours at 85°C with DC bias plus rated ripple current; post-test limits include capacitance change within ±20% and defined tan δ and leakage current criteria.
  • Operating Temperature Range — Specified for –40°C to +85°C to cover typical industrial thermal environments.
  • Compact Mechanical Footprint — Dimensions: L 13.5 cm × D 6.35 cm; Height (seated) provided in product data for mechanical planning.
  • Electrical Safety & Reliability — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket, and dielectric proof of AC 2500 V for 1 minute between terminal and bracket.
  • Polarized Electrolytic — Polarized design intended for DC bus and energy storage applications.
  • RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • Industrial Power Supplies — Bulk energy storage and smoothing for inverter circuitry and industrial DC bus systems.
  • AC Servomotor Drives — Handles high-frequency regenerative voltage and rapid charge–discharge cycles encountered in servo drives.
  • General Inverter Systems — Suitable for inverter front-ends and regenerative circuits that require high ripple-current capability and endurance.
  • High-Frequency Regeneration Circuits — Designed to cope with high-speed charge–discharge and elevated ripple at high frequencies.

Unique Advantages

  • High ripple-current tolerance — Rated ripple currents at both low and high frequencies support demanding power-conversion and regenerative applications.
  • Proven endurance under load — 5000-hour load-life rating at 85°C with defined post-test limits for capacitance, tan δ and leakage current, enabling predictable long-term behavior.
  • Smaller package for given performance — Designed to offer a smaller physical size while delivering higher ripple capability compared with alternatives in the same family.
  • Robust insulation and dielectric proof — High insulation resistance and AC dielectric proof between terminal and bracket enhance reliability in high-voltage installations.
  • Wide operating temperature range — –40°C to +85°C supports a broad range of industrial environments.
  • Regulatory compliance — RoHS conformity simplifies regulatory acceptance in global equipment builds.
