LNX2H222MSEG

The LNX2H222MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNX series, offering 2200 µF capacitance at a 500 V rating. It is engineered for high-ripple, extra-high-voltage industrial power applications such as inverter and power-supply circuitry where robust DC bus filtering and energy storage are required.

Designed for reliability in demanding environments, this polarized radial can features high ripple-current handling, a wide operating temperature range, and long-term endurance under rated ripple conditions.

Key Features

• Capacitance & Voltage – 2.2 mF (2200 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance for bulk energy storage in high-voltage DC systems.
• High Ripple Capability – Rated ripple current of 7.7 A at 120 Hz and 10.78 A at 100 kHz to support inverter and power-supply filtering under heavy AC ripple loads.
• Endurance at Rated Conditions – Endurance specified for parts rated at 500 V: performance validated for 5000 hours at +85°C when subjected to the specified D.C. bias plus rated ripple current.
• Construction & Mounting – Screw terminal, radial can package for secure, low-inductance connections suitable for industrial assemblies and easy field replacement.
• Temperature Range – Operates from −25 °C to +85 °C, matching common industrial ambient profiles.
• Leakage Current – After 5 minutes at rated voltage and 20 °C, leakage current is limited to ≤ 3√(C·V) µA or 5 mA (whichever is smaller), aiding predictable system standby and discharge behavior.
• Size & Mechanical – Physical dimension: L 13.0 cm × D 6.35 cm (screw-terminal radial can) for planning PCB/rail spacing and mechanical mounting.
• Regulatory & Materials – RoHS compliant; flame-retardant electrolyte is available for specified types in the LNX series.

Typical Applications

• Industrial Inverters – Bulk DC-link filtering and energy buffering in inverter assemblies where high voltage and high ripple currents are present.
• Power Supplies – Smoothing and decoupling on high-voltage power-supply rails in industrial and factory automation equipment.
• Motor Drives – Energy storage and ripple absorption in motor-control converters and PWM drive circuits.
• High-Voltage DC Systems – Capacitor bank segments or standalone units requiring robust screw-terminal connections and high-voltage rating.

Unique Advantages

• High-voltage performance: 500 V rating provides margin for extra-high-voltage DC bus designs and reduces the need for multiple series capacitors.
• Designed for high ripple: Explicit ripple-current ratings at both low and high frequencies enable reliable operation under realistic inverter and switching conditions.
• Proven endurance at 500 V: Endurance validated for 5000 hours at +85 °C under D.C. bias plus rated ripple current, supporting predictable long-term operation.
• Secure screw-terminal mounting: Robust mechanical and electrical connection suitable for industrial assemblies and maintenance-friendly replacement.
• Leakage control: Defined leakage-current limits after voltage application support predictable charge/discharge characteristics for system designers.
• RoHS compliant and flame-retardant options: Supports regulatory requirements and offers flame-retardant electrolyte types where specified.
