LNT2G392MSEGBN

The LNT2G392MSEGBN is a screw‑terminal aluminum electrolytic capacitor in Nichicon's LNT series, delivering 3.9 mF (3900 µF) at 400 V with a ±20% tolerance. Designed for general‑purpose power applications, it combines high ripple current capability and a long rated life for demanding industrial and power-electronics environments.

Key value propositions include high ripple handling (17.9 A at 120 Hz and 25.06 A at 100 kHz), a 5000‑hour endurance at 105 °C, and a robust screw‑terminal radial can package (φ63.5 × 150L) that simplifies secure electrical connections and high-current installations.

Key Features

• Capacitance and Voltage — 3.9 mF (3900 µF) rated at 400 V with ±20% tolerance for bulk energy storage and DC link applications.
• High Ripple Current — Low‑frequency ripple current 17.9 A at 120 Hz and high‑frequency ripple current 25.06 A at 100 kHz to support heavy AC ripple and switching workloads.
• Long Endurance at High Temperature — Rated life of 5000 hours at 105 °C when operated under specified ripple conditions, supporting long service intervals.
• Low Losses — Tangent of loss angle (tan δ) of 0.2 measured at 120 Hz, providing predictable dissipation characteristics.
• Leakage Current — Initial leakage current specified at 3740 µA, allowing straightforward margining in power designs.
• Rugged Mechanical Package — Radial, can‑style screw terminals (φ63.5 × 150L) with M5 terminal hardware for secure connections in heavy‑current assemblies.
• Operating Range and Compliance — Operating temperature −25 °C to +105 °C and RoHS compliant for regulatory alignment.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing in industrial and commercial DC power supplies, leveraging 3.9 mF capacitance and high ripple current ratings.
• Inverters and Motor Drives — DC link and filtering applications that require high ripple handling and reliable performance at elevated temperatures.
• Industrial Power Electronics — Energy buffering and decoupling in systems where long life at 105 °C and screw‑terminal connections are required for durable, high‑current assemblies.

Unique Advantages

• High ripple capability: 17.9 A at 120 Hz and 25.06 A at 100 kHz enable robust handling of both low‑ and high‑frequency ripple from rectifiers and switching converters.
• Extended high‑temperature life: 5000 hours at 105 °C provides predictable aging and maintenance planning for continuous‑duty applications.
• Screw‑terminal convenience: Radial can with screw terminals simplifies high‑current connections and mechanical mounting compared with leaded types.
• Designable loss profile: Specified tan δ of 0.2 at 120 Hz allows thermal and ESR budgeting in precision power designs.
• Regulatory readiness: RoHS compliance meets common environmental requirements for commercial and industrial equipment.
• Clear electrical margins: 400 V rating and ±20% capacitance tolerance give straightforward headroom for DC link and filtering designs.
