LNT1H224MSEN

The LNT1H224MSEN is a high-capacitance aluminum electrolytic capacitor in a screw-terminal radial can package designed for general-purpose power applications. With 220,000 µF at 50 V, a φ90 × 170 mm can size and screw terminals, it provides bulk energy storage and high ripple-current handling for demanding power filtering and buffering tasks.

Engineered for elevated operating conditions, this capacitor is rated for operation from −40°C to +105°C with an endurance specification of 2000 hours at 105°C, making it suitable for industrial power systems and other environments requiring robust, long-life bulk capacitance.

Key Features

• High Capacitance — 220,000 µF (220 mF) bulk capacitance for energy buffering and smoothing in power systems.
• Rated Voltage — 50 V working voltage suitable for mid-voltage DC buses and power-supply rails.
• Screw Terminal Mounting — Radial can with screw terminals for secure, high-current connections and easy installation into power assemblies.
• High Ripple Current Handling — Low-frequency ripple current 22 A at 120 Hz and high-frequency ripple current 25.3 A at 100 kHz to support heavy AC ripple and switching loads.
• Operating Temperature and Endurance — −40°C to +105°C operating range with a rated life of 2000 hours at 105°C under rated ripple conditions.
• Electrical Characteristics — ±20% capacitance tolerance at 120 Hz/20°C, tanδ 0.75 (20°C, 120 Hz), and leakage current specified at 5000 µA.
• Package and Size — Large-diameter φ90 × 170 mm can (L: 17 cm × D: 9 cm) for high-energy storage; radial, screw-terminal package case.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply bulk smoothing — Provides large bulk capacitance and high ripple-current capability for smoothing DC bus and intermediate rails.
• Industrial power systems — Suited for systems that need sustained operation at elevated temperatures and high ripple currents.
• Energy buffering / UPS modules — Large-capacitance storage for short-term energy buffering and ride-through support in backup power equipment.
• High-current power assemblies — Screw-terminal design enables secure connections in assemblies that demand reliable, high-current delivery.

Unique Advantages

• Massive energy storage: 220,000 µF capacitance delivers significant stored charge for bulk smoothing and buffering, reducing the need for multiple parallel caps.
• Robust ripple-current capability: 22 A (120 Hz) and 25.3 A (100 kHz) ripple ratings handle heavy AC components from rectifiers and switching converters.
• High-temperature endurance: Rated 2000 hours at 105°C under rated ripple conditions, providing predictable lifetime in hot operating environments.
• Secure mechanical connections: Screw terminals simplify installation and ensure reliable high-current terminations in power racks and modules.
• Wide ambient range: −40°C to +105°C operation supports a broad set of industrial and commercial environments.
• Regulatory compliance: RoHS compliance supports use in regulated product lines.
