LNX2W122MSEFBN

The LNX2W122MSEFBN is a screw‑terminal aluminum electrolytic capacitor in Nichicon's LNX series, specified at 1.2 mF (1200 µF) and 450 V. It is a polarized, radial can package with screw terminals designed for extra‑high voltage, high‑ripple applications.

Engineered for long life and high reliability, this part is intended for demanding power applications where sustained ripple handling, extended endurance at elevated temperature, and secure mechanical connections are required.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 450 V for energy storage and smoothing in high‑voltage circuits.
• High ripple current capability — Rated ripple current of 4.7 A at 120 Hz and 6.58 A at 100 kHz, enabling robust performance under continuous AC ripple stress.
• Long operational life — Endurance specification of 20,000 hours at +85 °C under rated ripple current conditions, supporting extended maintenance intervals.
• Screw terminal mounting — Radial can with screw terminals for secure, low‑impedance connections suitable for high‑current bus implementations.
• Operating temperature range — Specified for −25 °C to +85 °C to cover typical industrial ambient environments.
• Tolerance and polarity — Polarized capacitor with ±20% capacitance tolerance (at 120 Hz, 20 °C).
• Safety and materials — Flame retardant electrolyte option available; RoHS compliant (2011/65/EU, (EU)2015/863).
• Leakage current guidance — Leakage current meets the datasheet limit: after 5 minutes’ application of rated voltage, leakage is not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C).

Typical Applications

• Industrial power supplies / inverter circuitry — Provides high‑voltage energy buffering and ripple smoothing for inverter and power conversion stages.
• High‑voltage power conversion — Suited to applications that require extra‑high voltage capacitors with sustained ripple capability.
• Long‑life, high‑ripple environments — Useful where continuous ripple and extended endurance at elevated temperatures are design drivers.

Unique Advantages

• High‑voltage, high‑ripple capability: 450 V rating combined with multi‑amp ripple specifications enables stable performance in demanding power systems.
• Extended endurance at elevated temperature: 20,000 hours at +85 °C under rated ripple current reduces replacement frequency and supports long service life.
• Robust screw‑terminal connections: Screw terminals provide secure mechanical and electrical connection for high‑current and vibration‑prone installations.
• Polarized, radial can form factor: Familiar packaging simplifies mechanical integration into existing power assemblies.
• Safety and compliance: Flame retardant electrolyte option and RoHS compliance support regulatory and safety considerations in end products.
