LNU2W682MSEJBB

The LNU2W682MSEJBB is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series, specified at 6.8 mF and rated for 450 V DC. Designed for industrial power applications, it targets inverter circuitry and high‑frequency regenerative circuits where high voltage handling, robust ripple capability and reliable long‑life operation at elevated temperatures are required.

Built for rugged industrial environments, the part combines a compact can‑style screw‑terminal package with a wide operating temperature range and a defined 5000‑hour load life at 105°C under ripple current.

Key Features

• Capacitance & Voltage: 6.8 mF capacitance with a 450 V DC rating; capacitance tolerance ±20% (120 Hz, 20°C).
• Screw‑Terminal Package: Radial can with screw terminals for secure, low‑impedance electrical and mechanical connection suitable for industrial power assemblies.
• High‑Temperature Endurance: Rated for continuous operation from −40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple current.
• High Ripple Current Capability: Rated ripple current of 22.5 A at 120 Hz and 31.5 A at 10 kHz, supporting heavy AC and switching loads.
• Charge/Discharge Durability: Engineered to cope with high‑speed charge/discharge loading and high‑frequency regenerative voltages encountered in motor drives and inverters.
• Leakage Current Specification: After 5 minutes application of rated voltage, leakage current is not more than 3√CV (µA) or 5 mA, whichever is smaller (measured at 20°C).
• Compact Series Design: LNU series offers high voltage capability in a smaller envelope compared to previous LNT designs; this part’s package dimensions are L: 12.5 × D: 9 cm.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing in inverter power supplies where high voltage rating and ripple handling are required.
• Motor Drive Regeneration: High‑frequency regenerative voltage handling for AC servomotors, helping manage energy returned to the DC bus during braking.
• General Inverters: Energy buffering and decoupling in general inverter topologies subject to frequent charge/discharge cycles and elevated temperatures.

Unique Advantages

• High Voltage in a Smaller Envelope: LNU series design achieves higher voltage capability with reduced size relative to legacy designs, aiding compact power module layouts.
• Robust Ripple Performance: High rated ripple current at both low and high frequencies supports switching and regenerative loads with lower temperature rise.
• Long High‑Temperature Life: 5000‑hour load life at 105°C under rated ripple current provides predictable aging characteristics for industrial applications.
• Secure Mechanical Termination: Screw‑terminal construction ensures reliable, low‑resistance connections for heavy current paths and repeated serviceability.
• Durable Charge/Discharge Behavior: Tested for high‑speed charge/discharge and cyclic endurance to maintain capacitance, tan δ and leakage within specified limits after stress testing.
• Standards‑Oriented Design: Includes insulation resistance and voltage‑proof characteristics per the series’ datasheet to support safe integration into power systems.
