LNT1J224MSEN

The LNT1J224MSEN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series, specified at 220,000 µF and 63 V. It is a radial, can-type capacitor with screw terminals designed for general-purpose power applications that require large bulk capacitance and substantial ripple-handling capability.

Designed for operation from −40°C to +105°C and manufactured for mass production, this part balances high capacitance, robust ripple current ratings, and service life characteristics suitable for elevated-temperature installations.

Key Features

• Bulk Capacitance: 220,000 µF (220 mF) nominal capacitance for bulk energy storage and smoothing in DC systems.
• Rated Voltage & Polarization: 63 V rated voltage, polarized electrolytic construction for DC link and smoothing duties.
• Screw-Terminal Mounting: Radial can with screw terminals for secure, low-resistance connections and straightforward installation.
• Ripple Current Capability: Low-frequency ripple current 23.7 A (120 Hz) and high-frequency ripple current 27.25 A (100 kHz), enabling effective handling of sustained AC ripple across a broad frequency range.
• Loss and Leakage: Tangent of loss angle (tan δ) 0.6 (measured at 20°C, 120 Hz) and specified leakage current of 5,000 µA, allowing designers to account for dissipation and DC leakage in system budgets.
• Temperature and Endurance: Operating range −40°C to +105°C with rated endurance of 2,000 hours at +105°C under rated ripple conditions (per LNT series specifications for 10 to 250 V range).
• Physical Size & Packaging: Large-format footprint (φ90 × 220L; L: 22 cm × D: 9 cm) supplied in cardboard packing for bulk handling.
• Regulatory: RoHS compliant and in mass production.

Typical Applications

• Bulk energy storage and smoothing: Use where large capacitance is required to stabilize DC rails and absorb transient loads; the 220,000 µF value reduces the number of parallel capacitors needed.
• High-ripple power systems: Suitable for power supplies and DC-link circuits that must withstand sustained ripple currents up to 23.7 A (120 Hz) and 27.25 A (100 kHz).
• Elevated-temperature installations: Designed for equipment operating up to +105°C with a rated life of 2,000 hours at that temperature, enabling deployment in thermally demanding enclosures.
• Screw-terminal assemblies: Ideal for designs that require robust mechanical and electrical connections via screw terminals and a radial can package.

Unique Advantages

• Very large capacitance in a single component: 220,000 µF provides substantial energy storage capacity without extensive capacitor arrays, simplifying BOM and layout.
• High ripple handling across frequencies: Specified ripple currents at both 120 Hz and 100 kHz support designers addressing ripple from low-frequency rectification and higher-frequency switching sources.
• Designed for elevated operating temperatures: −40°C to +105°C range and 2,000-hour endurance at +105°C offers predictable life characteristics for high-temperature applications.
• Secure screw-terminal connectivity: Radial can with screw terminals offers durable, low-impedance connections suited to heavy-current paths and industrial mounting.
• Manufacturing readiness: RoHS compliance and mass-production status support procurement and scale-up for volume designs.
