LNT1K224MSE

The LNT1K224MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, designed for general-purpose power applications that require very large bulk capacitance. It combines a high capacitance (220000 µF) and an 80 V rated voltage in a robust radial can with screw terminals for secure, high-current connections.

This part is specified for demanding ripple-current environments and elevated operating temperatures, making it suitable where high stored energy and reliable DC bus smoothing are required within its rated conditions.

Key Features

• High Capacitance & Voltage — 220000 µF (220 mF) capacitance at an 80 V rated voltage, ±20% tolerance for bulk energy storage and smoothing.
• High Ripple-Current Capability — Rated low-frequency ripple current of 24.8 A at 120 Hz and high-frequency ripple current of 28.52 A at 100 kHz to handle substantial AC ripple on DC rails.
• Performance Parameters — Specified tan δ of 0.4 and leakage current up to 5000 µA, providing clear electrical performance bounds for design verification.
• Thermal and Lifetime Rating — Operates from −40 °C to +105 °C with a rated lifetime of 2000 hours at 105 °C under specified conditions.
• Robust Mechanical Design — Radial can package with screw terminals (φ100 × 250L size) for secure bolted connections; nominal bolt for φ100 is M8 per series dimensions.
• Compliance & Packaging — RoHS compliant and shipped in cardboard packing; part is in mass production.

Typical Applications

• High‑current DC bus filtering — Large 220000 µF capacitance and 80 V rating paired with 24.8 A / 28.52 A ripple capability make this capacitor suitable for smoothing and stabilizing DC bus voltages.
• Bulk energy storage — High stored charge density for systems that require significant energy buffering within the specified leakage and tolerance limits.
• Power electronics and converters — Designed for general-purpose power applications where sustained ripple current and elevated operating temperatures (−40 °C to +105 °C) are expected.

Unique Advantages

• Massive bulk capacitance: 220000 µF provides substantial smoothing and energy storage to help stabilize DC rails and reduce voltage excursions.
• High ripple handling: Rated ripple currents of 24.8 A (120 Hz) and 28.52 A (100 kHz) reduce stress from AC components in power systems and support higher throughput designs.
• Elevated temperature endurance: Rated for operation to +105 °C with a 2000 hour lifetime at that temperature, allowing deployment in thermally demanding environments within the specified rating.
• Secure screw-terminal mounting: Robust radial can with screw terminals and M8 nominal bolt for φ100 diameter ensure reliable mechanical and electrical connections in high-current assemblies.
• Clear electrical limits: Specified tan δ (0.4) and defined leakage current (5000 µA) provide deterministic parameters for thermal and leakage budgeting in designs.
• Regulatory compliance and production readiness: RoHS-compliant and in mass production with cardboard packing for straightforward procurement and integration.
