LNC2G392MSEGBB

The LNC2G392MSEGBB is an aluminum electrolytic capacitor in a screw-terminal can designed for industrial power applications. It delivers 3900 µF at 400 V with a polarized radial package and is optimized for high ripple-current and high-frequency regenerative environments.

Typical use cases include inverter circuitry and AC servomotor regenerative circuits where compact size, sustained ripple handling and long-term endurance are required. The device is rated for operation from −40 °C to +85 °C and is RoHS compliant.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Screw-Terminal, Polarized Package — Radial can with screw terminals for secure mechanical and electrical connections in power assemblies.
• High Ripple Current — Designed for elevated ripple: 16.5 A at 120 Hz and 23.1 A at 100 kHz, supporting high-frequency applications and fast charge–discharge cycles.
• Temperature & Lifetime — Operating range −40 °C to +85 °C with a rated load life of 5000 hours under ripple-current application at 85 °C.
• Electrical Reliability — Leakage current specification after 5 minutes: not more than 3√(V) µA or 5 mA (whichever is smaller). Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Endurance & Charge–Discharge Durability — Capacitance retention and dissipation characteristics are maintained after endurance tests (5000 h at 85 °C under rated ripple) and after 50 million charge–discharge cycles at room temperature (ΔV = rated × 0.3, 3 Hz).
• Compact Footprint — Smaller-sized design in the LNC series while providing higher ripple-current capability compared to referenced series within the same family.
• Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Used in inverter circuitry to smooth and stabilize DC link voltages under heavy ripple load.
• AC Servo & Motor Drives — Handles high-frequency regenerative voltages in servo systems and motor control applications.
• General Inverters and Power Conversion — Suitable for inverter and converter topologies requiring sustained ripple capability and high-frequency performance.
• High-Speed Charge–Discharge Systems — Designed to cope with frequent, rapid charge–discharge cycles found in power electronic subsystems.

Unique Advantages

• High ripple capability: Rated for 16.5 A at 120 Hz and 23.1 A at 100 kHz, enabling robust performance in demanding AC/DC and regenerative circuits.
• Long operational life under load: 5000 hours at 85 °C with rated ripple current ensures predictable long-term behavior in continuous-duty installations.
• Compact for power-class capacitors: Smaller-sized LNC-series design that delivers elevated ripple handling without increasing board footprint.
• Proven electrical robustness: Specified leakage current limits, insulation resistance >100 MΩ at DC 500 V and AC 2500 V voltage proof provide measurable safety margins for system designers.
• Durability for cyclic duty: Endurance validated through charge–discharge testing (50 million cycles) for applications with frequent switching and regenerative events.
• Regulatory compliance: RoHS conformity supports environmentally driven procurement and product design requirements.
