LNX2W272MSEHBN

The LNX2W272MSEHBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNX series, specified at 2.7 mF (2700 µF) and 450 V. It is engineered for high-ripple, extra-high-voltage applications where long operational life and secure screw-terminal connections are required.

Typical use cases include industrial power supplies and inverter circuitry; the part delivers high ripple-current capability, a rated endurance of 20,000 hours at +85°C under rated ripple current, and options suited for flame-retardant electrolyte requirements.

Key Features

• Capacitance & Tolerance — 2.7 mF (2700 µF) with ±20% tolerance (measured at 120 Hz, 20°C).
• Voltage Rating — Rated at 450 V for extra-high-voltage applications within the LNX series range.
• High Ripple Current — Rated ripple current 8.3 A at 120 Hz and 11.62 A at 100 kHz, supporting demanding power-conditioning workloads.
• Long Endurance — Designed for 20,000 hours of operation at +85°C when subjected to the rated ripple current and voltage conditions.
• Operating Temperature Range — Specified for operation from -25°C to +85°C.
• Screw Terminal Mounting — Radial can with screw terminals for robust, low-impedance connections in panel or chassis-mounted power assemblies.
• Leakage Current Specification — Leakage current limited per series specification: not more than 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at rated voltage (at 20°C).
• Safety & Compliance — Flame-retardant electrolyte versions are available; capacitor is RoHS compliant (2011/65/EU, (EU)2015/863).
• Package Dimensions — Radial can, screw-terminal package; size dimension L: 10 cm × D: 7.62 cm; maximum seated height 3.937 inch (as specified).

Typical Applications

• Industrial Power Supplies — Used for bulk energy storage and smoothing in industrial power supplies, including inverter circuit front ends where high ripple and high voltage are present.
• Inverter Circuitry — Suited for DC link and filtering in inverter modules that require extra-high-voltage capacitors with sustained ripple capability.
• General-Purpose Power Systems — Fits general-purpose power designs that need polarized, high-capacitance components with long operational life under continuous ripple stress.

Unique Advantages

• High ripple endurance: Rated ripple currents at both low and high frequencies (8.3 A @120 Hz, 11.62 A @100 kHz) reduce thermal stress during continuous operation.
• Extended lifetime at elevated temperature: 20,000-hour endurance at +85°C under rated ripple current supports long maintenance intervals and predictable performance.
• Extra-high-voltage capability: 450 V rating addresses applications that require higher DC bus voltages within the LNX series range.
• Secure screw-terminal connections: Radial can with screw terminals provides robust mechanical and electrical attachment for panel- or chassis-mounted power assemblies.
• Compliance and safety options: RoHS compliance plus availability of flame-retardant electrolyte variants help meet regulatory and safety-driven design choices.
• Clear electrical limits: Specified leakage current formula and impedance behavior at low temperature enable predictable sizing and derating in system design.
