LNC2W272MSEHBN

The LNC2W272MSEHBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power applications. With a rated capacitance of 2.7 mF (2700 µF) at 450 V and an operating range of –40 °C to +85 °C, it is optimized for inverter and regenerative power circuitry where compact size and high ripple-handling are required.

Key value comes from its higher ripple-current capability in a smaller package, a 5,000-hour load life at 85 °C under ripple current, and construction suited for high-speed charge–discharge and high-frequency regenerative voltages found in AC servomotor and inverter systems. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance at a 450 V rated voltage, with a tolerance of ±20%.
• High Ripple Current — Designed for demanding ripple environments: 13.7 A at 120 Hz and 19.18 A at 100 kHz, enabling operation under both low- and high-frequency ripple conditions.
• Temperature and Lifetime — Operates from –40 °C to +85 °C with a specified load life of 5000 hours at 85 °C when subjected to rated ripple current.
• Package & Termination — Radial can with screw terminals for secure electrical and mechanical connections in power assemblies.
• Robust Endurance Characteristics — After endurance testing (DC bias plus rated ripple for 5000 hours at 85 °C), specified limits include capacitance change within ±20%, tan δ within 200% of initial, and leakage current not exceeding initial specified value.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√V µA or 5 mA, whichever is smaller (measured at 20 °C).
• Compact Footprint — Smaller-sized design compared with related LNX and LNK series while delivering higher ripple capability; body dimensions: L 7.5 × D 7.62 cm.
• Standards & Compliance — Compliant with the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk and filtering capacitor for inverter power stages where high voltage (up to 450 V) and high ripple handling are required.
• AC Servomotor Drives — Handles high-frequency regenerative voltages and frequent charge–discharge cycles in motor drive regenerative circuits.
• Regenerative Power Supplies — Energy buffering and smoothing in high-frequency regenerative and braking systems for industrial equipment.
• High-Speed Power Conversion — Suitable for power conversion stages that require robust ripple performance at both 120 Hz and 100 kHz.

Unique Advantages

• Higher Ripple Capability: Specified ripple currents of 13.7 A (120 Hz) and 19.18 A (100 kHz) support demanding transient and continuous ripple loads.
• Compact Design: Smaller physical size compared to LNX and LNK series while maintaining elevated ripple performance, aiding space-constrained power assemblies.
• Long Load-Life under Ripple: 5000-hour endurance at 85 °C with rated ripple current provides predictable aging and replacement planning for industrial systems.
• Robust Mechanical Termination: Screw terminal construction provides reliable electrical contact and secure mounting in industrial environments.
• Designed for High-Frequency Use: Validated for high-frequency regenerative voltages and high-speed charge–discharge cycles commonly encountered in motor drives and inverters.
• Regulatory Compliance: RoHS conformity simplifies integration into products requiring restricted-substance compliance.
