LNT1H224MSE

The LNT1H224MSE is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require very large bulk capacitance and strong ripple-handling capability. It combines a 220,000 µF capacitance at a 50 V rating with a polarized radial can and screw-terminal mounting to support demanding DC power systems.

Engineered for elevated-temperature operation, the LNT1H224MSE is specified for –40°C to +105°C operation with a rated endurance of 2,000 hours at 105°C, making it suitable for systems that require sustained performance under heat and continuous ripple loading.

Key Features

• Capacitance & Voltage — 220,000 µF nominal capacitance at a 50 V rated voltage with a capacitance tolerance of –20% to +20%.
• High ripple capability — Specified low-frequency ripple current of 22,000 mA at 120 Hz and high-frequency ripple current of 25,300 mA at 100 kHz to support heavy AC ripple and high-duty DC applications.
• Thermal endurance — Rated for continuous operation from –40°C to +105°C with a life/endurance specification of 2,000 hours at 105°C under rated ripple conditions.
• Electrical characteristics — Specified tangent of loss angle (tan δ) of 0.75 (measured at 20°C, 120 Hz, 50 V) and a leakage current specified at 5,000 µA.
• Package & mounting — Radial can with screw terminals (φ90 × 170 mm overall size) for secure bolted connections and robust mechanical mounting; packaged in cardboard for shipment.
• Regulatory status — RoHS compliant.

Typical Applications

• Power supplies and DC bus energy storage — Large capacitance and high ripple ratings make this capacitor suitable for bulk energy storage and smoothing in high-current DC power supplies.
• Industrial power electronics — Screw-terminal mounting and high ripple capability support use in motor drives, inverters, and rectifier/filter circuits where sustained ripple handling is required.
• Backup power & UPS systems — High capacitance provides extended hold-up and energy buffering for systems that require temporary power during transitions.

Unique Advantages

• Very large bulk capacitance: 220,000 µF provides substantial energy storage in a single component, reducing the need for parallel arrays.
• High ripple current handling: 22 A (120 Hz) and 25.3 A (100 kHz) ratings enable reliable operation under continuous high-ripple conditions.
• Robust thermal specification: –40°C to +105°C range and a 2,000-hour rating at 105°C support long-term use in elevated-temperature environments.
• Screw-terminal mechanical reliability: Bolted screw terminals provide secure electrical connection suitable for heavy-current wiring and serviceability.
• Clear electrical limits: Specified tan δ and leakage current values allow designers to validate damping, loss, and standby current against system requirements.
• RoHS compliant: Meets regulatory requirements for restricted substances as provided in the product data.
