LNT1A154MSEB

The LNT1A154MSEB is an aluminum electrolytic capacitor in a screw-terminal radial can package offering 150,000 µF capacitance at a 10 V rating. It is a screw-terminal type designed for general-purpose applications that require large bulk capacitance and robust mechanical mounting.

Key characteristics include operation across −40°C to 105°C, an endurance specification of 2,000 hours at 105°C under rated ripple conditions, and high rated ripple current capabilities, making it suitable for designs that demand sustained energy storage and ripple handling in a compact cylindrical package (φ51 × 120L).

Key Features

• Capacitance and Voltage 150,000 µF (150 mF) rated at 10 V with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Ripple Current Handling Low-frequency ripple current rating of 10.8 A at 120 Hz and high-frequency ripple capability of 12.42 A at 100 kHz for demanding AC ripple environments.
• Thermal Endurance Rated for operation from −40°C to +105°C with an endurance rating of 2,000 hours at 105°C under DC bias plus rated ripple current.
• Leakage and Dissipation Specified leakage current of 3,670 µA and tangent of loss angle (tan δ) of 0.85 (measured at 20°C, 120 Hz).
• Screw-Terminal Radial Can Package φ51 × 120L cylindrical can with screw terminals (M5 nominal bolt for φ51), designed for secure electrical and mechanical connections.
• Regulatory Compliance RoHS compliant to the directive listed in the series datasheet.

Typical Applications

• General Purpose Power Systems — Provides large bulk capacitance where robust screw-terminal mounting and sustained ripple handling are required.
• Energy Storage and Smoothing — Used to stabilize DC bus voltages and supply bulk energy for transient loads in industrial and infrastructure equipment.
• High-Ripple Environments — Suitable for applications that require continuous ripple current handling at both low and high frequencies thanks to specified ripple ratings.

Unique Advantages

• Very Large Capacitance: 150,000 µF delivers substantial bulk energy storage in a single component, reducing the number of capacitors needed for large-capacitance requirements.
• High Ripple Capability: Rated ripple currents of 10.8 A (120 Hz) and 12.42 A (100 kHz) support demanding AC conditions and reduce thermal stress in high-ripple applications.
• High-Temperature Endurance: Endurance rating of 2,000 hours at 105°C under rated ripple makes the part suitable for sustained elevated-temperature operation.
• Secure Mechanical Connection: Screw-terminal radial can design with M5 nominal bolt for φ51 diameter provides reliable electrical contact and mechanical retention.
• Measured Electrical Characteristics: Specified tan δ (0.85 at 20°C, 120 Hz) and measured leakage current (3,670 µA) allow predictable design margining for loss and standby current.
• RoHS Compliant: Conforms to RoHS requirements noted in the series documentation for regulatory alignment.
