LNC2W392MSEGBB

The LNC2W392MSEGBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, rated at 3900 µF and 450 V. It is a smaller-sized, high-ripple-current electrolytic designed for energy buffering and DC link applications in industrial power electronics.

Engineered for inverter circuitry and high-frequency regenerative voltages such as those encountered in AC servomotor drives and general inverters, this capacitor offers a long load life and RoHS-compliant materials for industrial power-supply use.

Key Features

• Capacitance & Voltage — Nominal 3900 µF capacitance with a rated voltage of 450 V and ±20% tolerance.
• Screw Terminal Package — Radial can with screw terminals for secure, high-current connections suitable for chassis or bracket mounting.
• High Ripple Current — Supports 17.3 A at 120 Hz and 24.22 A at 100 kHz, enabling effective handling of AC ripple in power conversion circuits.
• Long Load Life & Endurance — Rated for 5000 hours of ripple-current application at 85°C; after endurance test, capacitance remains within ±20% and leakage/tan δ remain within specified limits.
• Operating Temperature & Stability — Specified for –40°C to +85°C with impedance stability data for low-temperature performance.
• Leakage & Insulation — Leakage current specification per datasheet: after 5 minutes at rated voltage, leakage is ≤ 3√(V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Compact Footprint — Smaller-sized option within the LNC family with dimensions L: 13.5 × D: 6.35 cm, suitable where space is constrained.
• RoHS Compliant — Manufactured in compliance with the RoHS Directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and DC-link smoothing in industrial converter and PSU designs where high ripple capability is required.
• Inverter & Motor Drive Systems — Supports inverter circuitry and AC servomotor regenerative circuits by handling rapid charge/discharge and high-frequency ripple.
• Regenerative Drive Circuits — Energy buffering for high-frequency regenerative voltages in servo and drive applications.
• General Purpose Energy Storage — General inverter and power electronics designs that require polarized aluminum electrolytic capacitance with robust terminal connections.

Unique Advantages

• High ripple handling: Rated ripple currents at both 120 Hz and 100 kHz deliver measurable capability for smoothing and DC-link duties in high-switching-frequency systems.
• Screw-terminal robustness: Provides reliable, low-resistance connections for high-current installations and secure mounting in chassis or bracketed assemblies.
• Long operational life: 5000 hours at 85°C under rated ripple conditions supports durability in continuous industrial operation.
• Wide temperature range: –40°C to +85°C rating enables use across typical industrial ambient conditions.
• Compact LNC-series form factor: Smaller size within the series offers space savings without sacrificing ripple performance.
• RoHS compliant materials: Meets current RoHS requirements for restricted substances.
