LNT1A154MSE

The LNT1A154MSE is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications that require very high capacitance and robust ripple handling. It delivers 150,000 µF at 10 V in a φ51×120 mm can with screw terminals for secure high‑current connections.

Key value comes from its combination of large capacitance, high low‑ and high‑frequency ripple current capability, and a wide operating temperature range up to 105°C—making it suitable for bulk energy storage, DC bus smoothing, and power supply filtering in demanding systems.

Key Features

• High Capacitance: 150,000 µF (150 mF) for extended energy storage and long hold‑up times in power systems.
• Rated Voltage: 10 V working voltage for low‑voltage power rails and DC link applications.
• Screw Terminal Mounting: Radial can with screw terminals and M5 nominal bolt for secure, low‑impedance connections.
• High Ripple Current Capacity: 10.8 A at 120 Hz (low frequency) and 12.42 A at 100 kHz (high frequency) to support heavy AC ripple and switching currents.
• Endurance at Elevated Temperature: Rated for 2,000 hours at 105°C under specified ripple conditions.
• Wide Operating Temperature: −40°C to +105°C for deployment in a range of environmental conditions.
• Capacitance Tolerance: ±20% (–20% to +20%) at 120 Hz, 20°C.
• Electrical Characteristics: Tangent of loss angle (tan δ) 0.85 (measured at 20°C, 120 Hz) and specified leakage current of 3,670 µA.
• Packaging & Compliance: Supplied in cardboard packing and RoHS compliant.

Typical Applications

• General‑purpose power supplies: Bulk filtering and hold‑up where high capacitance and significant ripple current capability are required.
• DC bus smoothing for converters: Stabilizes DC link voltage in converters and inverters that generate high ripple currents.
• Industrial power electronics: Robust screw terminals and wide temperature range support deployment in industrial power systems and controllers.

Unique Advantages

• Large energy reservoir: 150,000 µF provides substantial stored charge for extended hold‑up and smoothing, reducing the need for parallel components.
• High ripple handling: 10.8 A (120 Hz) and 12.42 A (100 kHz) ratings allow the capacitor to accommodate both low‑ and high‑frequency ripple from switching supplies.
• Secure, low‑resistance connections: Screw‑terminal construction with M5 nominal bolts enables reliable, serviceable high‑current terminations.
• Engineered for elevated temperature operation: 2,000‑hour endurance at 105°C under rated conditions supports long‑term operation in hot environments.
• Clear electrical parameters: Specified tan δ and leakage current values enable predictable behavior in critical designs.
• Regulatory compliance: RoHS‑compliant material set simplifies integration into products requiring restricted‑substance conformance.
