LNT2W103MSEJBN

The LNT2W103MSEJBN from Nichicon is a screw-terminal aluminum electrolytic capacitor offering 10,000 µF capacitance at a 450 V rating. Designed as a radial, screw-terminal can (φ90 × 220L), it targets general-purpose high-voltage power applications that require large bulk storage and robust ripple handling.

Key value comes from its high ripple-current capability, extended 5,000-hour life at 105°C, and a screw-terminal package that supports secure, low-impedance connections in industrial and power-electronic assemblies.

Key Features

• Capacitance & Voltage — 10,000 µF rated capacitance with a 450 V rating and ±20% tolerance (measured at 120 Hz, 20°C), providing substantial energy storage for DC bus and bulk filtering.
• High Ripple-Current Performance — Rated ripple current of 35.1 A at 120 Hz and 49.14 A at 100 kHz, enabling effective smoothing under both low- and high-frequency ripple conditions.
• Low Dissipation Factor — tanδ (DF) specified at 0.2 maximum (20°C, 120 Hz), supporting efficient operation with reduced heating from internal losses.
• Endurance at Elevated Temperature — Rated load life of 5,000 hours at +105°C when subjected to D.C. bias plus rated ripple current, for predictable long-term performance in high-temperature environments.
• Screw-Terminal, Radial Can Package — φ90 × 220L radial can with screw terminals for secure bolted connections; nominal bolt size for φ90 is M5 per series dimensional data.
• Wide Operating Range — Specified operating temperature range from −25°C to +105°C to match demanding industrial thermal environments.
• Leakage Current — Specified leakage current up to 5,000 µA after rated voltage application, consistent with large-value, high-voltage electrolytic capacitors.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing on high-voltage DC buses where 10,000 µF at 450 V is required.
• Industrial power supplies — Screw-terminal mounting and high ripple capability support secure installation and reliable filtering in industrial power electronics.
• High-energy DC-link applications — Large capacitance combined with rated ripple currents supports DC-link and bulk capacitor roles in power conversion systems.

Unique Advantages

• High-voltage bulk storage: 10,000 µF at 450 V provides significant stored energy per component, reducing the number of capacitors required in high-voltage designs.
• Robust ripple handling: 35.1 A (120 Hz) and 49.14 A (100 kHz) ripple ratings let the capacitor manage substantial AC stress from converters and rectifiers.
• Thermal and lifecycle predictability: 5,000-hour life at 105°C with specified endurance metrics supports planning for long-term reliability in elevated-temperature installations.
• Secure electrical connection: Screw-terminal package (radial can) with M5-compatible bolt provision simplifies mounting and low-impedance connections in heavy-current layouts.
• Design transparency: Clear electrical and mechanical specifications (capacitance, tolerance, tanδ, leakage, dimensions) support accurate BOM and thermal/mechanical integration.
