LNX2L222MSEHBN

The LNX2L222MSEHBN is a high-voltage, screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It delivers 2.2 mF capacitance at 550 V in a radial can with screw terminals, optimized for applications that require high ripple current handling and extra-high-voltage performance.

Targeted at industrial power supplies and inverter circuitry, this capacitor combines high ripple capability, polarized screw-terminal mounting, and long-life endurance to support robust DC-link and smoothing functions in demanding systems.

Key Features

• High voltage and capacitance — 2.2 mF (2200 µF) rated for 550 V provides substantial energy storage for DC-link and smoothing applications.
• High ripple current capability — Rated ripple current of 8 A at 120 Hz and 11.2 A at 100 kHz supports heavy ripple environments in power converters and inverters.
• Long-life endurance for 550 V parts — Specified endurance of 5000 hours at +85°C when subjected to rated ripple current and peak voltage, with post-test limits on capacitance change, tan δ, and leakage current.
• Operating temperature range — Specified for operation from −25°C to +85°C to suit industrial ambient conditions.
• Screw terminal, radial can package — Robust screw-terminal mounting and radial can construction for secure electrical and mechanical connections in power assemblies; size dimension L: 13 × D: 7.62 cm and seated height max 5.118 inch.
• Low leakage specification — Leakage after 5 minutes at 20°C not more than 3√(C·V) µA or 5 mA, whichever is smaller, helping maintain DC-link stability after charge.
• Low-temperature stability — Impedance stability characterized with Z(−25°C)/Z(+20°C) ≤ 8, supporting performance in cooler operating conditions.
• RoHS compliant and safety options — Complies with RoHS (2011/65/EU, (EU)2015/863); flame-retardant electrolyte variants are available within the LNX series.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for high-voltage power supplies used in industrial equipment.
• Inverter circuitry — DC-link and ripple filtering in inverter systems where high voltage and high ripple current are required.
• Extra-high-voltage power electronics — Applications that demand both high capacitance and elevated voltage ratings for energy buffering and decoupling.
• High-ripple environments — Power conversion stages and converters that generate significant ripple currents across a wide frequency range.

Unique Advantages

• High-voltage energy capacity: 2.2 mF at 550 V delivers substantial stored energy per component, reducing the number of capacitors needed for a given DC-link energy.
• Designed for heavy ripple: Specified ripple currents at both low and high frequencies (8 A at 120 Hz, 11.2 A at 100 kHz) support reliable operation in switching power stages.
• Proven endurance for 550 V parts: Rated for 5000 hours at +85°C under rated ripple conditions, providing predictable long-term performance in elevated-temperature installations.
• Robust mechanical termination: Screw terminals provide secure electrical and mechanical connections for assembly and maintenance in industrial systems.
• Measurable leakage control: Leakage current limits (≤ 3√(C·V) µA or 5 mA after 5 minutes at 20°C) help preserve system stability after charging and during long-term service.
• Regulatory and safety options: RoHS compliance and available flame-retardant electrolyte types support environmental and safety considerations in system design.
