LNX2G332MSEG

The LNX2G332MSEG is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNX series designed for general‑purpose and industrial power applications. It delivers 3300 µF capacitance at a 400 V rating in a radial can with screw terminals, offering high ripple tolerance and extended operational life for power supply and inverter circuitry.

With an operating range of -25 °C to 85 °C and a rated endurance of 20,000 hours at 85 °C, this capacitor targets applications that require robust bulk energy storage, smoothing and ripple handling in higher‑voltage systems.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) nominal capacitance with a 400 V rated voltage and tolerance of -20% to +20%.
• Screw‑Terminal Radial Can Package — Screw terminal mounting provides secure electrical and mechanical connection for high‑current power electronics; package described as radial, can with screw terminals and nominal dimensions φ63.5 × 130 mm.
• Long Operational Life — Specified lifetime of 20,000 hours at +85 °C under rated ripple current conditions as defined by the LNX series endurance test.
• High Ripple Current Capability — Rated ripple current 9.6 A at 120 Hz and 13.44 A at 100 kHz for handling AC ripple in power conversion stages.
• Wide Temperature Range — Rated for operation from -25 °C to +85 °C with low‑temperature impedance ratio Z(-25 °C)/Z(+20 °C) up to 8.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current ≤ 3√(C·V) µA or 5 mA, whichever is smaller (measurement at 20 °C), per series datasheet.
• RoHS Compliant — Manufactured in compliance with RoHS directives as specified for the LNX series.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for inverter and power conversion stages in industrial supply designs.
• Inverter Circuitry — Handles high ripple currents and DC bias plus rated ripple for inverter DC link filtering and energy buffering.
• General Purpose High‑Voltage Systems — Use where 400 V rated capacitance and long life at elevated temperatures are required for reliable performance.

Unique Advantages

• Extended Endurance: 20,000‑hour rated life at 85 °C under rated ripple current, supporting long maintenance intervals and predictable lifetime planning.
• High Ripple Handling: Specified ripple currents at both low and high frequencies (9.6 A at 120 Hz, 13.44 A at 100 kHz) enable effective suppression of AC fluctuations in power electronics.
• Screw‑Terminal Reliability: Screw terminals deliver secure mechanical and electrical connections suitable for high‑current, field‑serviceable installations.
• Defined Low‑Temperature Behavior: Impedance characteristic at -25 °C is specified (Z ratio ≤ 8 versus +20 °C), allowing designers to predict performance in cooler environments.
• Clear Electrical Limits: Leakage current and endurance recovery conditions are provided in the datasheet, enabling rigorous qualification and margin calculations.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products with restricted‑substance requirements.
