LNX2H682MSEJ

The LNX2H682MSEJ is a screw-terminal, radial can aluminum electrolytic capacitor rated at 6.8 mF (6800 µF) and 500 V. It is designed for extra-high-voltage, high-ripple applications and suited for industrial power supplies and inverter circuitry where durable DC-link filtering and energy smoothing are required.

Key value propositions include high allowable ripple current, robust long-life performance at elevated temperature, and a screw-terminal package for secure, low-impedance connections in heavy-duty power assemblies.

Key Features

• Electrical Performance  6.8 mF capacitance at a 500 V rating with a capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High Ripple Capability  Supports 18.5 A at 120 Hz and 25.9 A at 100 kHz, enabling use in high-ripple DC-link and inverter applications.
• Reliability & Lifetime  Designed for long-life operation under rated conditions with a specified lifetime of 5000 hours at +85°C for parts rated at 500 V when subjected to the specified ripple and bias conditions.
• Leakage Current Specification  After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller.
• Mechanical & Mounting  Screw terminal mounting in a radial can package (φ90 × 170L) for secure bolted connections and straightforward field serviceability.
• Operating Temperature  Rated for operation from −25°C to +85°C.
• Optional Flame-Retardant Electrolyte  Flame-retardant electrolyte types are available within the series for improved safety characteristics.
• RoHS Compliance  Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies  Designed for use in industrial power supplies, including inverter circuitry that requires extra-high-voltage DC-link capacitance and high ripple handling.
• High-Ripple DC-Link Filtering  Used where sustained ripple current and voltage smoothing are required in power conversion stages.
• Power Conversion Modules  Suitable for assemblies that need robust screw-terminal connections and radial can packaging for heavy-duty power assemblies.

Unique Advantages

• High Voltage Rating:  500 V rating provides headroom for extra-high-voltage power designs and DC-link applications.
• Quantified Ripple Performance:  Specified ripple current ratings (18.5 A at 120 Hz; 25.9 A at 100 kHz) let designers size cooling and lifespan expectations precisely.
• Measured Lifetime Specification:  A defined 5000-hour endurance at +85°C for 500 V parts gives a verifiable basis for reliability planning under rated conditions.
• Screw-Terminal Robustness:  Screw terminal connections simplify installation in high-current, high-vibration systems and support secure mechanical integration.
• Leakage Current Limit:  Clear leakage current formula (≤ 3√CV µA or 5 mA after 5 minutes) enables predictable standby and hold-up behavior in power designs.
• Regulatory Compliance:  RoHS conformity and availability of flame-retardant electrolyte options support regulatory and safety considerations.
