LNU2G153MSEJ

The LNU2G153MSEJ is a screw‑terminal aluminum electrolytic capacitor designed for high‑voltage industrial power applications. It delivers 15,000 µF capacitance at a 400 V rating with a −40 °C to +105 °C operating range and is optimized for inverter circuitry and regenerative voltage environments.

Built for high ripple and rapid charge–discharge loading, this radial can with screw terminals offers long‑life performance and RoHS compliance for industrial power supplies, AC servo drives and general inverters.

Key Features

• Capacitance & Voltage: 15,000 µF (15 mF) nominal capacitance at a 400 V rated voltage; rated voltage range up to DC 525 V according to the series specification.
• High‑Temperature Endurance: Designed for continuous operation up to 105 °C with a specified load life of 5,000 hours when subjected to rated ripple current and DC bias.
• High Ripple Current Capability: Rated ripple current of 33.5 A at 120 Hz and 46.9 A at 10 kHz, suitable for high‑frequency inverter and regenerative applications.
• Screw Terminal, Radial Can Package: Robust screw‑terminal connections in a radial can package for secure mounting and low‑impedance system integration.
• Wide Temperature Range: Operates from −40 °C to +105 °C to support industrial environments.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (C = µF, V = V), per the datasheet.
• Charge–Discharge Endurance: Engineered to withstand repeated high‑speed charge–discharge cycles; series endurance test includes 50 million cycles (ΔV = rated voltage ±0.3 at 3 Hz) with specified post‑test limits for capacitance, tan δ, and leakage.
• Dimensional & Mechanical: Radial can with screw terminals; size dimensions listed as L: 19.5 × D: 9 cm and height seated max specified in product data.
• Polarized Design: Polar electrolytic capacitor suitable for DC bus, smoothing and energy buffer roles in power electronics.
• RoHS Compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Used for bulk energy storage and smoothing in high‑voltage industrial DC power systems and inverter front ends.
• Inverter and Motor Drives: Provides high ripple handling and fast charge–discharge capability for general inverters and AC servomotor regenerative circuits.
• Regenerative Energy Circuits: Suited for high‑frequency regenerative voltages and frequent energy recovery cycles where robust ripple performance is required.
• High‑Frequency Power Electronics: Supports applications requiring elevated ripple current at both low (120 Hz) and high (10 kHz) frequencies.

Unique Advantages

• High Voltage Flexibility: Rated at 400 V with series capability up to DC 525 V, enabling use across a range of high‑voltage power designs.
• Long High‑Temperature Life: 5,000 hour load life at 105 °C under rated ripple and DC bias supports sustained reliability in demanding thermal environments.
• Strong Ripple Performance: High rated ripple currents (33.5 A at 120 Hz, 46.9 A at 10 kHz) reduce stress in inverter and regenerative circuits and help maintain DC bus stability.
• Robust Mechanical Termination: Screw terminals and radial can packaging provide secure, low‑resistance connections for heavy current paths and serviceability.
• Validated Charge–Discharge Durability: Series endurance testing for tens of millions of charge–discharge cycles demonstrates suitability for frequent energy cycling applications.
• Regulatory Compliance: RoHS conformity supports environmentally conscious designs and supply‑chain requirements.
