LNC2W822MSEJBB

The LNC2W822MSEJBB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power electronics. It delivers 8200 µF at 450 V with a polarized design and a compact package optimized for high ripple-current and high-frequency regenerative applications.

Engineered for inverter circuitry and AC servomotor regenerative voltage handling, this capacitor combines high ripple capability, extended load life at elevated temperature, and robust charge–discharge endurance for demanding industrial power-supply systems.

Key Features

• Electrical performance: 8200 µF rated capacitance with ±20% tolerance and 450 V rated voltage, providing substantial bulk energy storage for DC link and filtering applications.
• High ripple-current capability: Designed for heavy AC load — 30.5 A at 120 Hz and 42.7 A at 100 kHz — to support high-frequency switching and regenerative currents.
• Temperature and stability: Operates from −40 °C to +85 °C; impedance stability is specified across the temperature range consistent with series characteristics.
• Reliability and lifetime: Load life specified as 5000 hours at 85 °C under rated ripple current and DC bias; endurance requirements ensure capacitance, tan δ, and leakage remain within specified limits after test duration.
• Charge–discharge endurance: Qualified for repetitive charge–discharge stress (50 million cycles at ΔV = 0.3 × Vrated, cycle 3 Hz) to withstand high-speed switching environments.
• Robust insulation and leakage controls: Leakage current specification after 5 minutes is not more than 3√(V) µA or 5 mA (whichever is smaller) at 20 °C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket, and voltage proof AC 2500 V for 1 minute.
• Mechanical and mounting: Screw terminal radial-can package provides secure electrical and mechanical connections for industrial assemblies; compact external dimensions (L: 13.5 × D: 9 cm) for space-efficient installations.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverters: Bulk DC-link and smoothing for inverter power stages where high ripple current handling and long life at 85 °C are required.
• AC servomotor drives: Support for high-frequency regenerative voltage and rapid charge–discharge cycles in motion-control systems.
• High-frequency regenerative circuits: Energy storage and filtering in regenerative braking and bidirectional power-flow applications.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies reduce the need for parallel capacitors or oversized components in high-switching environments.
• Extended operational life at elevated temperature: 5000-hour load-life rating at 85 °C offers predictable long-term performance under continuous ripple loading.
• Durable charge–discharge capability: Proven endurance for tens of millions of charge–discharge cycles, improving reliability in applications with frequent energy reversals.
• Secure screw-terminal mounting: Provides robust electrical and mechanical connections for heavy-current industrial systems, simplifying installation and maintenance.
• Space-conscious form factor: Radial can construction with compact L and D dimensions supports tighter power-supply layouts without sacrificing performance.
• Regulatory compliance: RoHS conformity supports use in equipment targeting current environmental requirements.
