LNC2W153MSEJ

The LNC2W153MSEJ is a screw‑terminal aluminum electrolytic capacitor designed for high‑power industrial applications. It delivers 15,000 µF capacitance at a 450 V rating in a rugged radial can with screw terminals, optimized for inverter and regenerative power circuits where high ripple handling and long life are required.

With a rated temperature range of −40°C to +85°C and a 5,000‑hour load life at 85°C under rated ripple conditions, this capacitor is aimed at power electronics designers who need stable bulk energy storage, high ripple tolerance, and reliable long‑term performance.

Key Features

• High Capacitance and Voltage — 15,000 µF at 450 V provides substantial bulk energy storage for DC link and smoothing applications.
• Designed for High Ripple — Rated ripple current of 43.1 A at 120 Hz and 60.34 A at 100 kHz, supporting heavy AC and high‑frequency charge/discharge loads.
• Long Load Life — 5,000 hours endurance at 85°C with D.C. bias plus rated ripple current, with defined limits on capacitance change, tan δ, and leakage current after test.
• Robust Temperature Range — Operates from −40°C to +85°C with low‑temperature impedance stability (Z at −40°C ≤ 8× Z at +20°C).
• Mechanical and Mounting — Radial can with screw terminals (φ90×215L; 21.5 × 9.0 cm), suitable for secure bolted connections in power assemblies.
• Electrical Safety and Insulation — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Polarized with Standard Tolerance — Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20°C, and low loss (tan δ = 0.2 specified).
• RoHS Compliant — Conforms to applicable RoHS directive requirements for environmental compliance.

Typical Applications

• Industrial Inverters — DC link and smoothing capacitor for inverter power stages where high ripple current and long life are required.
• AC Servomotor Drives — Energy storage and regenerative voltage handling in servomotor and motion control systems.
• High‑Frequency Power Supplies — Bulk capacitor for supplies that require fast charge/discharge cycles and stable performance at elevated ripple frequencies.

Unique Advantages

• High energy density for DC link use: 15,000 µF at 450 V delivers significant stored energy to stabilize DC rails and absorb transient loads.
• Exceptional ripple handling: Specified ripple currents at both low and high frequencies reduce thermal stress and extend system reliability under demanding duty cycles.
• Proven endurance under load: 5,000‑hour life at 85°C with defined post‑test limits ensures predictable aging and simplifies lifecycle planning.
• Robust insulation and voltage proofing: High insulation resistance and 2.5 kV AC isolation between terminal and bracket improve safety margins in high‑voltage assemblies.
• Application‑focused form factor: Screw‑terminal radial can enables secure, low‑impedance connections ideal for heavy current power systems.
• Regulatory compliance: RoHS status supports inclusion in environmentally regulated products and systems.
