LNT2H222MSEG

The LNT2H222MSEG is a Nichicon LNT-series aluminum electrolytic capacitor in a screw-terminal can, providing 2.2 mF (2200 µF) rated at 500 V. It is a polarized, general-purpose power capacitor designed for applications that require high-voltage capacitance with robust screw-terminal connections and high ripple-current capability.

Key value propositions include high-voltage energy storage (500 V), elevated operating temperature capability up to 105°C, and robust ripple-current performance for demanding power-electronics environments.

Key Features

• Electrical Performance — 2.2 mF (2200 µF) capacitance with ±20% tolerance and a rated voltage of 500 V; tan δ (DF) = 0.2 measured at 20°C, 120 Hz.
• High Ripple Current — Low-frequency ripple handling of 9.3 A at 120 Hz and high-frequency ripple handling of 13.02 A at 100 kHz, supporting significant AC stress in power stages.
• Leakage and Polarization — Polarized design with specified leakage current of 3140 µA after rated voltage application.
• Thermal & Endurance — Operating temperature range −25°C to +105°C with rated endurance of 2000 hours at 105°C under rated ripple and DC bias (per LNT series endurance conditions for 500 V parts).
• Mechanical & Mounting — Screw terminal mounting in a radial can package (φ63.5 × 130 mm); secure bolted connections for high-current terminals and easy mechanical retention.
• Packaging & Production — Supplied in cardboard packing and currently in mass production.
• Regulatory — RoHS compliant.

Typical Applications

• General-Purpose Power Electronics — High-voltage capacitance and high ripple-current capability make the LNT2H222MSEG suitable for bulk energy storage and smoothing in general-purpose power designs.
• Power Supplies and Converters — The 500 V rating and robust screw-terminal connections support DC bus filtering and decoupling where secure, high-current terminations are required.
• Industrial Power Systems — Elevated operating temperature (up to 105°C) and rated endurance of 2000 hours at 105°C enable use in demanding industrial power environments that require sustained performance.

Unique Advantages

• High Voltage with Substantial Capacitance: 2.2 mF at 500 V provides significant energy storage for high-voltage systems without resorting to parallel arrays.
• Strong Ripple-Handling Capability: 9.3 A (120 Hz) and 13.02 A (100 kHz) ripple-current ratings reduce the need for extensive paralleling for AC stress mitigation.
• Screw Terminal Reliability: Screw-terminal radial can package enables secure, low-impedance connections for high-current and high-reliability assemblies.
• High-Temperature Endurance: Rated to operate to 105°C with an endurance rating of 2000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Clear, Measured Loss Characteristics: Specified tan δ of 0.2 (20°C, 120 Hz) provides predictable dissipation behavior for thermal and ripple planning.
• RoHS Compliant and Production-Ready: RoHS compliance and mass-production status simplify procurement and regulatory planning.
