LNX2H122MSEGBB

The LNX2H122MSEGBB from Nichicon is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage, high‑ripple applications. Built in a radial can with screw terminals, it targets industrial power hardware such as power supplies and inverter circuitry where robust DC‑link and energy‑buffering performance is required.

With a 1.2 mF (1200 µF) capacitance at 500 V rating, polarized construction, and extended endurance under elevated ripple conditions, this part delivers long operational life and stable performance across a −25 °C to 85 °C operating range.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance (at 120 Hz, 20 °C).
• Screw‑Terminal Radial Can — Secure screw‑terminal mounting for reliable high‑current connections in industrial assemblies.
• High Ripple Current — Rated ripple current of 4.8 A at 120 Hz and 6.72 A at 100 kHz, supporting demanding ripple environments.
• Long Life at Elevated Temperature — Designed for 5000 hours at 85 °C for 500 V parts when subject to rated conditions, providing predictable long‑term endurance.
• Wide Operating Temperature — Specified for operation from −25 °C to +85 °C to cover typical industrial thermal conditions.
• Leakage & Stability — Leakage current limited to 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20 °C; low‑temperature impedance ratio Z(−25 °C)/Z(+20 °C) up to 8.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Industrial Power Supplies — Suitable for DC‑link and smoothing duties in industrial power supplies, especially inverter circuitry where high ripple capability is required.
• General Purpose High‑Voltage Systems — Use in general purpose high‑voltage designs that require polarized, high‑capacitance bulk storage.
• Power Conversion Equipment — Appropriate for power conversion modules that need durable capacitors rated for sustained ripple and elevated temperatures.

Unique Advantages

• High Voltage Rating: 500 V rating enables use in extra‑high voltage industrial circuits without stepping down system voltage requirements.
• High Ripple Handling: Specified ripple current at both low and high frequencies reduces thermal stress and supports reliable operation under dynamic loads.
• Predictable Endurance: 5000‑hour qualification at 85 °C for 500 V parts provides clear expectations for lifetime under rated ripple conditions.
• Robust Mechanical Connection: Screw‑terminal package offers secure, low‑resistance connections suitable for high‑current applications and field serviceability.
• Operational Stability: Defined leakage current limits and impedance behaviour at low temperature support dependable performance across the specified temperature range.
• Regulatory Compliance: RoHS compliance simplifies integration into products requiring restricted‑substance conformity.
