LNT2G392MSEG

The LNT2G392MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, offering 3.9 mF (3900 µF) capacitance at a 400 V rating. It is a radial can with screw terminals, polarized, and designed for general-purpose power applications that require high ripple current handling and extended high-temperature endurance.

Featuring a rated operating range up to 105°C and a series-specified load life of 5,000 hours at 105°C, this component is targeted at high-voltage power systems where robust energy storage and reliable performance under sustained ripple current are required.

Key Features

• High Capacitance — 3.9 mF (3900 µF) provides substantial energy storage for power smoothing and bulk decoupling in high-voltage circuits.
• 400 V Rated Voltage — Suited for applications requiring a 400 V DC rating within the LNT series extended voltage range.
• Screw Terminal Mounting — Radial can with screw terminals enables secure, high-current connections and straightforward installation in power assemblies.
• High Ripple Current Capability — Rated ripple current of 17.9 A at 120 Hz and 25.06 A at 100 kHz supports heavy AC ripple conditions and fast switching environments.
• High-Temperature Endurance — Rated for operation from −25 °C to +105 °C (for 160–500 V range) with a rated load life of 5,000 hours at 105 °C per the LNT series specification.
• Polarized with Standard Tolerance — Polarized construction with capacitance tolerance of −20% to +20% (±20% typical at 20 °C, 120 Hz).
• RoHS Compliant — Meets RoHS directive requirements as specified for the LNT series.
• Compact, Industry-Scale Form — Size: L: 15 × D: 6.35 cm; height seated maximum 5.906 inch, suitable for installations requiring high-voltage electrolytic cans with screw terminals.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing where a 400 V, high-capacitance, high-ripple component is required.
• Power Conversion and Inverter Systems — DC link and ripple-current-intensive stages benefiting from the high ripple ratings and 105 °C endurance.
• Motor Drives and Servo Power — Energy buffering and decoupling in high-voltage motor drive circuits using screw-terminal connections for reliable high-current wiring.

Unique Advantages

• High Voltage and High Capacitance Combination: 400 V rating paired with 3.9 mF capacitance delivers substantial stored energy for demanding power applications.
• Designed for Sustained Ripple: Specified ripple currents (17.9 A at 120 Hz, 25.06 A at 100 kHz) enable longer service life under AC ripple and switching loads.
• Heat-Resilient Operation: Rated operation to 105 °C with a 5,000-hour load-life rating at that temperature supports designs with elevated operating temperatures.
• Robust Mechanical Termination: Screw terminal construction provides reliable, low-resistance connections for high-current assemblies and simplifies field installation.
• Series-Level Reliability Data: LNT series specifications (endurance, leakage current, stability at low temperature and shelf life) apply, providing verifiable performance expectations for design validation.
