LNC2G153MSEJBN

The LNC2G153MSEJBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, offering 15 mF capacitance at a 400 V rating. It is a smaller-sized, high-ripple-current design intended for industrial power electronics where high-frequency loading, rapid charge-discharge cycles, and long-term stability at elevated temperatures are required.

Target use cases include inverter circuitry and regenerative power circuits for AC servomotors and general inverters. Key value propositions are high ripple-current capability, robust endurance at 85°C, and compatibility with screw-terminal radial-can mounting for secure power connections.

Key Features

• Screw Terminal Package — Radial can with screw terminals for secure, high-current power connections and straightforward installation.
• Nominal Capacitance & Voltage — 15 mF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — 42.9 A at 120 Hz and 60.06 A at 100 kHz, supporting heavy AC loading and high-frequency operation.
• Temperature Range — Rated for operation from –40°C to +85°C, suitable for typical industrial ambient conditions.
• Long Load Life / Endurance — Designed for 5000 hours of applied ripple current at 85°C; endurance criteria include capacitance change within ±20% and leakage current and tan δ within specified limits after test.
• Charge–Discharge Durability — Meets series qualification for endurance after 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz cycle) at room temperature.
• Leakage & Insulation — Leakage current specified as not more than 3√(V) μA or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Voltage Proof — Withstands AC 2500 V for 1 minute between terminal and bracket with no abnormality.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Footprint — Radial can with screw terminals; size dimension L: 18.5 × D: 9 cm.

Typical Applications

• Industrial Power Supplies — Used in inverter front-ends and DC-link circuits where sustained ripple current and stable capacitance are needed.
• AC Servomotor Regeneration — Suited for high-frequency regenerative voltage applications in motor-drive systems.
• General Inverters and Motor Drives — Supports high-speed charge–discharge loading and energy buffering in inverter topologies.
• High-Frequency Power Electronics — Appropriate where elevated ripple current at kHz-range frequencies is required for reliable operation.

Unique Advantages

• High ripple capability in a compact form — Delivers 42.9 A (120 Hz) and 60.06 A (100 kHz) while being smaller-sized compared with LNX/LNK series options.
• Designed for elevated-temperature endurance — Specified for 5000 hours under rated ripple current at 85°C, enabling predictable life in hot operating environments.
• Robust charge–discharge resilience — Qualification includes 50 million charge–discharge cycles, supporting repeated high-speed cycling in regenerative systems.
• Clear electrical safety margins — Defined leakage-current limits, insulation resistance, and a 2500 V AC voltage-proof test provide measurable safety parameters for design validation.
• Regulatory compliance — RoHS-compliant for deployments requiring restricted-substance conformity.
