LNC2V392MTEG

The LNC2V392MTEG is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNC series designed for industrial power applications. It is a polarized, stud‑bolt mount radial can capacitor specified for high ripple current handling and high‑speed charge‑discharge environments.

With a rated voltage of 350 V, capacitance of 3.9 mF, an operating temperature range of −40 °C to +85 °C, and a 5000‑hour load life at 85 °C under ripple current, this part targets inverter and regenerative power circuits where compact size and sustained ripple performance matter.

Key Features

• Electrical Performance — Rated capacitance 3.9 mF and rated voltage 350 V provide bulk energy storage for DC bus smoothing and power buffering in inverter systems.
• High ripple‑current capability — Rated ripple current of 14.9 A at 120 Hz and 20.86 A at 100 kHz supports heavy AC and high‑frequency ripple loads commonly seen in inverter and regenerative circuits.
• Reliability and load life — Designed for 5000 hours of applied ripple current at 85 °C, meeting endurance and stability requirements for continuous industrial operation.
• Mechanical package & mounting — Screw‑terminal radial can with stud/bolt mount delivers robust electrical connection and mechanical retention for high‑vibration industrial assemblies.
• Operating range and tolerance — Polarized device with a −20% to +20% capacitance tolerance and a temperature range of −40 °C to +85 °C for broad environmental coverage.
• RoHS compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).
• Compact footprint — Smaller-sized design within the LNC series; physical dimensions L: 8.5 cm × D: 6.35 cm help conserve PCB and chassis space.

Typical Applications

• Industrial inverters — DC bus energy storage and smoothing for general inverter circuitry, leveraging high ripple capability and 350 V rating.
• AC servo drives — Handling high‑frequency regenerative voltages and rapid charge‑discharge cycles in servo motor power stages.
• Regenerative power systems — Absorbing and smoothing returned energy in systems with frequent braking/regeneration events.
• High‑frequency power supplies — Supporting high‑frequency ripple currents (100 kHz) in switched power topologies requiring compact, high‑current capacitors.

Unique Advantages

• High ripple‑current rating: Supports 14.9 A at 120 Hz and 20.86 A at 100 kHz, allowing the capacitor to handle both low‑frequency and high‑frequency stress in power converters.
• Designed for continuous industrial use: 5000‑hour load life at 85 °C under ripple current provides predictable longevity in demanding power applications.
• Robust screw‑terminal mounting: Stud/bolt mount and screw terminals enable secure electrical connections and mechanical stability in vibration-prone environments.
• Wide ambient tolerance: Rated for −40 °C to +85 °C operation, enabling deployment across typical industrial temperature ranges.
• Space‑efficient form factor: Smaller-sized LNC series design with compact L × D footprint to support denser power assemblies.
• Regulatory compliance: RoHS conformity helps meet environmental and supply‑chain requirements.
