LNX2L103MSEK

The LNX2L103MSEK is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, offering 10,000 µF capacitance at a 550 V rating. It is a radial can with screw terminals designed for high-ripple, extra-high-voltage industrial power applications.

Engineered for industrial power supplies and inverter circuitry, this part provides high ripple-current capability and long-term reliability at elevated temperature. The device is RoHS compliant and a flame-retardant electrolyte version is available.

Key Features

• Capacitance & Voltage — 10,000 µF (10 mF) rated at 550 V, suitable for extra-high-voltage DC bus and energy-storage roles.
• Screw Terminal Mounting — Radial, can-style package with screw terminals for secure, low-resistance connections in power assemblies.
• High Ripple Capability — Standard ripple current ratings of 25.2 A at 120 Hz and 35.28 A at 100 kHz, supporting demanding switching and inverter loads.
• Operating Temperature Range — Specified for −25 °C to +85 °C operation to match industrial ambient conditions.
• Endurance at Elevated Temperature — Qualified for 5,000 hours at +85 °C (for parts rated at 500 V and 550 V) under DC bias plus rated ripple current; capacitance change remains within ±20% and leakage current stays at or below initial specified values after test.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C), enabling predictable power-loss budgeting.
• Tolerance & Low‑Temperature Stability — Capacitance tolerance ±20% (120 Hz, 20 °C); impedance ratio Z(−25 °C)/Z(+20 °C) ≤ 8 for operation in cooler environments.
• Compliance & Safety Options — RoHS compliant; flame-retardant electrolyte versions are available within the series.

Typical Applications

• Industrial Power Supplies — DC bus and bulk energy storage in industrial PSUs where high voltage and high ripple handling are required.
• Inverter Circuitry — Energy smoothing and ripple absorption for power inverters and motor-drive front ends.
• General-Purpose High‑Voltage Systems — Use in assemblies that require a high-voltage electrolytic capacitor with robust terminal connections and predictable endurance at elevated temperature.

Unique Advantages

• Extra-high voltage capability: The 550 V rating enables use in high-voltage DC link and converter applications without series stacking.
• High ripple-handling: Measured ripple currents of 25.2 A (120 Hz) and 35.28 A (100 kHz) support modern switching topologies with reduced overheating risk.
• Long-term reliability at temperature: Endurance validated for 5,000 hours at +85 °C under rated conditions for 500 V/550 V parts, ensuring predictable life in industrial environments.
• Secure screw-terminal packaging: Radial can with screw terminals simplifies heavy-current interconnects and mechanical mounting in power assemblies.
• Predictable leakage behavior: Leakage current limits defined by 3√(C·V) µA or 5 mA after initial voltage application, aiding thermal and leakage budgeting.
• Regulatory and safety-focused options: RoHS compliance and availability of flame-retardant electrolyte variants support regulatory and safety requirements.
