LNX2V273MSEK

The LNX2V273MSEK is a high-capacitance aluminum electrolytic capacitor in a screw-terminal, radial can package designed for industrial power applications. With a rated capacitance of 27,000 µF at 350 V and an operating range of -25 °C to +85 °C, it addresses DC link smoothing and high-voltage energy storage in inverter and industrial power-supply systems.

Engineered for extended life under ripple stress, this part delivers long-term reliability with 20,000 hours of rated ripple endurance at 85 °C and is supplied in cardboard packing for mass-production use. The product is RoHS compliant.

Key Features

• High Capacitance and Voltage — 27,000 µF at 350 V provides substantial energy storage for DC-link smoothing and bulk filtering in high-voltage power systems.
• Screw Terminal, Radial Can Package — Screw-terminal construction with a radial can (φ100 × 250 mm) enables robust, torque-ready connections for power assemblies.
• Long Endurance — Rated for 20,000 hours at +85 °C under standard ripple current, ensuring extended service life in sustained high-stress environments.
• High Ripple Capability — Specified ripple current handling of 42 A at 120 Hz and 58.8 A at 100 kHz supports heavy AC ripple and switching-frequency stress in inverter and converter circuits.
• Wide Operating Temperature — Specified for use from -25 °C to +85 °C to match common industrial ambient conditions.
• Leakage and Tolerance — Capacitance tolerance of ±20% and leakage current limits per datasheet (3√CV µA or 5 mA, whichever is smaller after 5 minutes at 20 °C).
• RoHS Compliant — Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing for inverter front ends and high-voltage power modules.
• Inverter Circuits — DC link capacitor for motor drives and frequency converters where high ripple handling and voltage rating are required.
• Power Conditioning — Filtering and decoupling in high-voltage DC systems to stabilize bus voltages during load transients.

Unique Advantages

• Substantial Energy Density: 27,000 µF at 350 V provides large stored energy per component, reducing the number of devices required for bulk capacitance.
• Designed for Continuous Ripple: Rated ripple currents at 120 Hz and 100 kHz accommodate both low-frequency and switching-frequency stress in power electronics.
• Extended High-Temperature Life: 20,000-hour endurance at +85 °C under rated ripple current supports long maintenance intervals and predictable aging.
• Robust Mechanical Termination: Screw terminals on an M8-compatible φ100 can simplify assembly and deliver secure electrical connections for high-current paths.
• Regulatory Compliance: RoHS-compliant materials ease integration into environmentally regulated products and supply chains.
