LNX2H272MSEH

The LNX2H272MSEH is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNX series, rated at 500 V and 2700 µF with a ±20% tolerance. It is designed for high-ripple, extra-high-voltage applications and is suited specifically for industrial power supplies and inverter circuitry where robust capacitive filtering and long operational life are required.

Key value propositions include high ripple current capability, a polarized screw-terminal package for secure connections, a -25°C to +85°C operating range, and RoHS compliance.

Key Features

• Capacitance & Voltage — 2700 µF nominal capacitance at a 500 V rated voltage with ±20% tolerance.
• Screw-Terminal Package — Radial can with screw terminals for secure, low-inductance connections in industrial layouts.
• High Ripple Current — Rated ripple performance of 8.8 A at 120 Hz and 12.32 A at 100 kHz to support high-demand power stages.
• Operating Temperature & Endurance — Rated for operation from -25°C to +85°C; specified endurance for 500 V parts is 5,000 hours at +85°C under rated ripple conditions.
• Leakage & Low-Temperature Behavior — Leakage current after 5 minutes is specified as not more than 3√(C·V) µA or 5 mA (whichever is smaller); impedance at -25°C can be up to 8× the impedance at +20°C.
• Polarized — Designed for polarized DC applications.
• Safety & Compliance — Flame-retardant electrolyte types are available and the part is RoHS compliant.
• Physical Size — Package dimensions include length 11 cm × diameter 7.62 cm (radial can, screw terminals).

Typical Applications

• Industrial Power Supplies — Bulk and smoothing capacitor for high-voltage power supplies used in industrial systems and inverter circuitry.
• Inverter and Converter DC Links — Provides high-ripple current handling for DC bus filtering in inverter and power conversion stages.
• General-Purpose High-Voltage Use — Intended for general-purpose applications requiring extra-high voltage capacitors with robust mechanical terminations.

Unique Advantages

• High Voltage Capability: The 500 V rating enables use in extra-high-voltage circuits without series stacking of lower-voltage parts.
• High Ripple Endurance: Specified ripple currents at both 120 Hz and 100 kHz support demanding power-stage ripple environments.
• Long Life at Elevated Temperature: Endurance specified as 5,000 hours at +85°C for 500 V parts when operated under rated ripple conditions, supporting sustained industrial operation.
• Robust Screw-Terminal Mounting: Screw terminals and a radial can package provide durable, low-impedance connections for heavy-current applications.
• Compliance and Safety Options: RoHS compliance and optional flame-retardant electrolyte types support regulatory and safety considerations.
• Clear Leakage and Low-Temperature Specs: Defined leakage-current limits and impedance behavior at -25°C enable predictable performance across temperature extremes.
