LNT1H154MSEB

The LNT1H154MSEB is a large-can, screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It delivers 150000 µF capacitance at a 50 V rating in a radial can with screw terminals, intended for general-purpose power applications that require high bulk capacitance and substantial ripple handling.

Designed for operation from −40°C to +105°C with a rated endurance of 2000 hours at 105°C, this capacitor provides high low- and high-frequency ripple current capability and robust leakage and dissipation characteristics for demanding power designs.

Key Features

• Capacitance & Voltage — 150000 µF nominal capacitance with a 50 V rated voltage and ±20% capacitance tolerance, providing significant bulk energy storage for DC systems.
• Screw-Terminal Mounting — Radial can package with screw terminals for secure, low-resistance connections; suitable for heavy-current wiring and mechanical retention.
• High Ripple Current — Low-frequency ripple current of 19.5 A at 120 Hz and high-frequency ripple current of 22.43 A at 100 kHz, enabling effective smoothing under high AC ripple conditions.
• Thermal and Lifetime Performance — Rated operating range −40°C to +105°C with an endurance rating of 2000 hours at 105°C when subjected to rated ripple and DC bias.
• Electrical Losses and Leakage — Specified tangent of loss angle (tanδ) 0.75 (measured at 20°C, 120 Hz) and leakage current up to 5000 µA for predictable dissipation and leakage behavior.
• Form Factor — Compact large-can dimensions: diameter φ90 mm × length 140 mm (L: 14 cm × D: 9 cm), shipped in cardboard packing for handling and storage.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Power supply bulk smoothing — Large capacitance and high ripple ratings make this capacitor suitable for stabilizing DC bus and bulk energy requirements in power converters.
• DC link / energy storage — High µF value and substantial ripple capability support short-term energy buffering and DC-link stabilization in power electronics.
• Industrial power equipment — Screw-terminal mounting and robust thermal endurance suit assemblies that require secure connections and sustained operation at elevated temperatures.

Unique Advantages

• Large-capacitance solution: 150000 µF provides significant bulk energy storage in a single component, reducing the number of parallel units required.
• High ripple handling: Rated for 19.5 A (120 Hz) and 22.43 A (100 kHz) ripple currents, enabling reliable smoothing under heavy AC ripple conditions.
• Robust thermal endurance: 2000-hour life at 105°C under rated ripple current provides predictable long-term performance in high-temperature environments.
• Screw-terminal reliability: Secure screw connections suitable for high-current, serviceable installations and straightforward mechanical mounting.
• Measurable loss characteristics: Specified tanδ (0.75 at 20°C, 120 Hz) and defined leakage current (up to 5000 µA) allow designers to model dissipation and standby losses accurately.
• RoHS compliant: Meets RoHS requirements for environmental compliance and global deployment.
