LNU2W153MTEJ

The LNU2W153MTEJ is a screw‑terminal aluminum electrolytic capacitor designed for industrial power electronics. This stud‑mount, high‑voltage capacitor is optimized for inverter and regenerative circuits where high ripple handling and high‑frequency charge/discharge are required.

Key characteristics include a 15 mF capacitance at 450 V DC, operation across −40 °C to 105 °C, and a 5,000‑hour rated life at 105 °C under ripple load. The part combines high voltage capability with a compact screw‑terminal can package for robust mounting in power assemblies.

Key Features

• Capacitance & Voltage — 15 mF nominal capacitance with a rated voltage of 450 V DC and ±20% tolerance (120 Hz, 20 °C).
• High‑Temperature Endurance — Rated for operation to 105 °C with a specified load life of 5000 hours at 105 °C under rated ripple conditions.
• High Ripple Current Capacity — Designed to handle significant ripple: 34.5 A at 120 Hz and 48.3 A at 10 kHz, supporting both low‑ and high‑frequency applications.
• Charge‑Discharge Durability — Engineered to cope with high‑speed charge/discharge cycles, with endurance tested for repeated charge/discharge events per series specifications.
• Package & Mounting — Radial can with screw terminals and stud bolt mount for secure mechanical and electrical connection in industrial assemblies.
• Wide Operating Temperature Range — Specified from −40 °C to +105 °C for reliable performance across demanding environments.
• RoHS Compliant — Conforms to RoHS directives noted in the product data.
• Compact Footprint — Smaller sized within the LNU series while retaining high voltage performance; physical size listed as L: 23.5 × D: 9 cm for board‑level and chassis planning.

Typical Applications

• Industrial Inverters — Bulk energy storage and ripple smoothing in inverter power stages, supporting efficient motor drive operation.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltages and frequent charge/discharge cycles found in servo drives.
• Industrial Power Supplies — DC bus filtering and energy buffering in high‑voltage industrial power supplies used for automation and motion control.
• High‑Frequency Power Electronics — Suited for applications requiring robust high‑frequency ripple handling and fast transient response.

Unique Advantages

• High Voltage Capability: 450 V rated voltage (series up to DC 525 V) provides margin for high‑voltage DC bus designs.
• Long Life at Elevated Temperature: 5000 hours at 105 °C under ripple load supports longevity in continuous‑duty industrial systems.
• Strong Ripple Performance: High allowable ripple currents at both 120 Hz and 10 kHz reduce the need for parallel components to meet ripple demands.
• Robust Mechanical Mounting: Stud bolt mount and screw terminals enable secure installation and low‑impedance connection in power assemblies.
• Designed for Fast Cycling: Specified endurance for high‑speed charge/discharge makes it suitable for regenerative and pulse‑loaded circuits.
• Regulatory Compliance: RoHS compliance simplifies placement in designs with environmental directive requirements.
