LNX2L122MSEG

The LNX2L122MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNX series, rated at 1200 µF and 550 V. Designed for industrial power applications, it provides high-voltage energy storage with screw-terminal mounting for secure electrical and mechanical connections.

Its value proposition centers on high ripple-current capability, extended endurance at elevated temperature, and robust leakage and dissipation specifications, making it suitable for inverter circuitry and other general-purpose high-voltage power systems.

Key Features

• Capacitance & Voltage: 1200 µF nominal capacitance with a 550 V rated voltage and ±20% tolerance, suitable for extra-high-voltage applications.
• High ripple capability: Rated ripple current of 5 A at 120 Hz (low frequency) and 7 A at 100 kHz (high frequency) to support demanding power-conversion loads.
• Dissipation factor (tan δ): Specified tan δ of 0.2 at 20°C and 120 Hz, enabling predictable loss and thermal behavior under AC stress.
• Leakage current: Initial leakage current specified at 2430 µA.
• Endurance: 5000 hours life at 85°C (endurance tested with rated ripple and DC bias as specified in the LNX series documentation).
• Operating temperature range: −25°C to +85°C for general-purpose industrial use.
• Package & mounting: Radial can with screw terminals (φ63.5 × 110L overall size) for secure, serviceable connections; nominal mechanical dimensions L: 11 × D: 6.35 cm.
• Regulatory: RoHS compliant.
• Production & packing: In mass production and supplied in cardboard packing.

Typical Applications

• Industrial power supplies: Suited for inverter circuitry and related industrial power electronics where high-voltage energy storage and reliable ripple handling are required.
• High-voltage power conversion: Used in extra-high-voltage DC filtering and energy-buffering stages that need 550 V rated components with substantial ripple-current capability.
• General-purpose industrial electronics: Applicable to a broad range of general-purpose systems that require polarized aluminum electrolytic capacitors with robust endurance at elevated temperatures.

Unique Advantages

• High-voltage rating (550 V): Supports extra-high-voltage designs without the need for series stacking of lower-voltage capacitors.
• Strong ripple-handling: 5 A (120 Hz) and 7 A (100 kHz) ripple ratings help reduce thermal stress and support continuous operation in power-conversion circuits.
• Endurance at elevated temperature: 5000 hours at 85°C provides predictable lifetime performance for demanding industrial environments.
• Screw-terminal package: Provides secure, low-resistance connections and straightforward installation or replacement in field serviceable equipment.
• Clear specification set: Defined tan δ, leakage, tolerance, and temperature range enable precise design margining and thermal management.
• RoHS compliance: Meets regulatory requirements for restricted substances in applicable regions.
