LNX2V223MSEK

The LNX2V223MSEK is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple applications. It provides 22,000 µF capacitance at a 350 V rating and is specified for operation from −25 °C to +85 °C.

Engineered for industrial power systems, particularly inverter circuitry and other extra-high-voltage uses, this part emphasizes high ripple-current capability and long operational life under rated ripple conditions.

Key Features

• Capacitance & Voltage: 22,000 µF (22 mF) rated at 350 V, ±20% tolerance, suited for large DC bus and energy storage requirements.
• Screw Terminal Mounting: Robust radial can with screw terminals for secure, low-inductance connections in industrial power assemblies.
• High Ripple Current: Rated ripple current of 38 A at 120 Hz and 53.2 A at 100 kHz, enabling effective smoothing under heavy AC ripple conditions.
• Long Life at Elevated Temperature: Designed for 20,000 hours of operation at +85 °C when subjected to rated ripple current, supporting extended maintenance intervals.
• Operating Temperature Range: Specified for −25 °C to +85 °C to accommodate common industrial thermal environments.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is ≤ 3√(C·V) µA or 5 mA (whichever is smaller) at 20 °C, for predictable DC performance.
• Safety & Compliance: Flame-retardant electrolyte option available; compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Device: Conventional polarized aluminum electrolytic design for DC filter and smoothing applications.
• Package Dimensions: Radial can with screw terminals; size stated as L: 22 × D: 10 cm for mechanical planning.

Typical Applications

• Industrial power supplies: Used in inverter and high-voltage power supply DC buses where high capacitance and ripple tolerance are required.
• Extra-high-voltage applications: Suited for circuits demanding elevated voltage ratings and robust ripple handling.
• General-purpose high-voltage filtering: Employed where long life and stable smoothing under sustained ripple are needed.

Unique Advantages

• High ripple endurance: Substantial ripple-current ratings at both low and high frequencies reduce heating and improve performance in demanding power environments.
• Extended operational life at +85 °C: 20,000-hour endurance at rated ripple current lowers replacement frequency and supports long-term system uptime.
• Robust electrical characteristics: Tight, verifiable leakage current limits and ±20% capacitance tolerance deliver predictable behavior in DC circuits.
• Secure, serviceable connections: Screw-terminal construction provides reliable mechanical and electrical connections for industrial assemblies.
• Standards-compliant materials: RoHS compliance and availability of flame-retardant electrolyte help meet regulatory and safety considerations.
