LNX2V182MSEFBB

The LNX2V182MSEFBB is a screw-terminal aluminum electrolytic capacitor designed for high-voltage power-electronics applications. It provides 1.8 mF (1800 µF) capacitance at a 350 V rating in a radial can package with robust screw terminals for secure, high-current connections.

Built for industrial power supplies and inverter circuitry, this part emphasizes high ripple-current handling and long operational life—rated for 20,000 hours at rated ripple current at +85°C—making it suitable where sustained performance and reliability are required.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a 350 V rated voltage and ±20% capacitance tolerance at 120 Hz, 20°C.
• High Ripple Current — Designed for elevated ripple environments with specified ripple currents of 5.6 A at 120 Hz and 7.84 A at 100 kHz.
• Long-Life Endurance — Endurance specification: 20,000 hours at 85°C under rated ripple current, with defined limits on capacitance change, dissipation factor, and leakage after the test.
• Robust Screw-Terminal Package — Radial can with screw terminals for secure bolted connections in high-current power applications; available mounting bracket dimensions and terminal pitch options per series guidelines.
• Operating Temperature Range — Specified for operation from -25°C to +85°C, with a low-temperature impedance characteristic (Z(-25°C)/Z(+20°C) = 8) noted in the series specification.
• Leakage Current Control — Leakage current after 5 minutes is limited to 3√(C·V) μA or 5 mA, whichever is smaller, ensuring predictable DC characteristics at 20°C.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in high-voltage industrial supply rails where sustained ripple tolerance is needed.
• Inverter and Motor Drive Circuits — DC-link and filtering use in inverter circuitry, leveraging high ripple-current rating and 350 V capability.
• Power Conditioning and Energy Storage — Charge/holding and transient energy buffering in medium-high voltage power-electronic systems.
• General Purpose High-Voltage Applications — Applications requiring polarized aluminum electrolytic capacitance with screw-terminal mounting for secure electrical connections.

Unique Advantages

• High ripple-current capability: Specified ripple ratings at both low and high frequencies (5.6 A at 120 Hz, 7.84 A at 100 kHz) support demanding power-electronics workloads.
• Extended operational life: Rated for 20,000 hours at +85°C under rated ripple current, providing predictable long-term behavior for maintenance planning and lifecycle cost reduction.
• Secure screw-terminal mounting: Radial can with screw terminals enables robust mechanical and electrical connections for high-current and vibration-prone environments.
• Controlled leakage behavior: Leakage current limits (3√CV μA or 5 mA) and endurance leakage requirements help ensure stable DC performance over time.
• Wide temperature usability: Specified -25°C to +85°C operating range and documented impedance behavior at low temperature support consistent performance across common industrial conditions.
• Regulatory compliance: RoHS conformity supports use in equipment targeting modern environmental compliance requirements.
