LNU2G153MTEJ

The LNU2G153MTEJ from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNU series designed for high-voltage industrial power applications. This polarized, radial-can module is optimized for inverter circuitry and regenerative power systems where high ripple handling and compact high-voltage capability are required.

Key value comes from its 15 mF capacitance at a 400 V rating, high ripple-current capability across low and high frequencies, long elevated-temperature load life, and compatibility with standard stud-bolt mounting for secure mechanical and electrical connections.

Key Features

• Capacitance & Voltage — 15 mF capacitance rated for 400 V DC, suitable for high-voltage energy storage in industrial power stages.
• High Ripple Current — Handles 33.5 A at 120 Hz and 46.9 A at 10 kHz, enabling robust performance under heavy AC ripple and high-frequency regenerative conditions.
• High-Temperature Endurance — Rated for continuous operation from −40 °C to +105 °C with a load life of 5000 hours at 105 °C under rated ripple conditions.
• Package & Mounting — Radial, can-style package with screw terminals and stud-bolt mount for reliable mechanical fixation and low-impedance connections in power assemblies.
• Polarization & Tolerance — Polarized device with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863), supporting environmentally regulated designs.
• Insulation & Voltage Proof — Designed with insulation resistance of more than 100 MΩ at DC 500 V (terminal to bracket) and withstands AC 2500 V for 1 minute without abnormality.

Typical Applications

• Industrial Power Supplies – Inverter Circuits: Energy storage and smoothing in inverter front ends and DC link applications for industrial drives.
• AC Servomotor Regeneration: Handling high-frequency regenerative voltages and rapid charge–discharge events in servo drive regenerative networks.
• General Inverters: Bulk capacitance and ripple filtering for general-purpose inverter systems where high voltage and high ripple capability are required.
• High-Speed Charge–Discharge Circuits: Suitable for circuits subject to rapid voltage transitions and frequent charge–discharge cycles.

Unique Advantages

• High-voltage capability: 400 V rating (series rated up to DC 525 V) supports demanding industrial DC-link and energy storage needs without series stacking.
• Superior ripple tolerance: Specified ripple currents at both 120 Hz and 10 kHz provide predictable thermal and electrical behavior across a wide frequency range.
• Extended high-temperature life: 5000-hour load life at 105 °C under rated ripple current offers reliability for continuous industrial operation.
• Compact high-voltage form factor: Marketed as smaller-sized compared to previous LNT series parts, enabling tighter packaging in power assemblies.
• Robust electrical isolation: High insulation resistance and AC voltage-proof characteristics support safe operation between terminals and mounting bracket.
• Secure mounting: Stud-bolt mounting with screw terminals ensures low-impedance, vibration-resistant connections for industrial environments.
