LNX2V122MSEF

The LNX2V122MSEF is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNX series, optimized for high‑voltage, high‑ripple applications. It delivers 1,200 µF capacitance at a 350 V rating with a polarized radial can and screw terminal mounting for secure, high-current connections.

Designed for industrial and general‑purpose power electronics, the part combines high ripple capability and extended endurance to support inverter circuitry and other demanding power supply duties where long life and reliable smoothing are required.

Key Features

• Capacitance and Voltage — 1,200 µF (1.2 mF) rated at 350 V with ±20% tolerance for bulk energy storage and smoothing in high‑voltage circuits.
• High Ripple Handling — 4.2 A low‑frequency ripple current at 120 Hz and 5.88 A high‑frequency ripple current at 100 kHz to support heavy ripple loads in power converters.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.2 at 20°C/120 Hz and a specified leakage current of 1,940 µA to characterize dissipation and insulation behavior under typical conditions.
• Long Endurance — 20,000 hours rated life at 85°C under specified ripple conditions, enabling extended maintenance intervals in continuous‑operation systems.
• Robust Mechanical Package — Radial, can‑style package with screw terminals (φ51 × 70L) for sturdy mounting and reliable terminal connections in industrial assemblies.
• Operating Temperature Range & Compliance — Rated for −25°C to +85°C operation and RoHS compliant; supplied in cardboard packing and available in mass production quantities.

Typical Applications

• Industrial Power Supplies — Suited for inverter circuitry and other industrial supply functions that require high‑voltage smoothing and sustained ripple performance.
• High‑Voltage DC Filtering — Use in DC link and bulk filtering where 350 V ratings and high ripple capability reduce voltage fluctuation and improve converter stability.
• General‑Purpose Power Electronics — Applicable across general‑purpose designs that need long life at elevated temperature and robust terminal mounting for secure connections.

Unique Advantages

• High ripple current capacity: 4.2 A (120 Hz) and 5.88 A (100 kHz) ratings allow the capacitor to handle significant AC stress without immediate degradation, supporting demanding power stages.
• Extended operational life: 20,000 hours at 85°C under rated ripple conditions reduces replacement frequency and lowers total cost of ownership in continuous‑operation equipment.
• Secure screw‑terminal mounting: Screw terminals provide reliable mechanical and electrical connections for high‑current bus applications and simplify installation in field serviceable systems.
• Clear performance characterization: Specified tan δ (0.2 at 20°C/120 Hz) and measured leakage current (1,940 µA) enable predictable design margins and faster validation in prototypes.
• RoHS compliant and production ready: RoHS status plus cardboard packing and mass production availability support compliant manufacturing and straightforward supply integration.
