LNT1A154MSEN

The LNT1A154MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering a high 150000 µF capacitance at a 10 V rated voltage with ±20% tolerance. It is a polarized, radial can package with screw terminals designed for general-purpose power applications that require large bulk capacitance and robust ripple handling.

Designed for operation from −40 °C to +105 °C and endurance of 2000 hours at 105 °C under rated ripple conditions, this module delivers long-term bulk energy storage and ripple dissipation in systems that need high capacitance and reliable mounting via screw terminals.

Key Features

• High Capacitance: 150000 µF nominal capacitance provides substantial bulk energy storage for smoothing and load support in power subsystems.
• 10 V Rated Voltage with ±20% Tolerance: Rated at 10 V with ±20% capacitance tolerance (120 Hz, 20 °C), enabling predictable capacitance behavior within the stated tolerance band.
• Screw Terminal Mounting: Radial can package with screw terminals (M5 nominal bolt for φ51) for secure, low-impedance connections and easy mechanical integration.
• High Ripple Current Capability: Rated low-frequency ripple current 10.8 A (120 Hz) and high-frequency ripple current 12.42 A (100 kHz), supporting sustained ripple handling across frequencies.
• Endurance at Elevated Temperature: Specified life of 2000 hours at 105 °C when subjected to rated ripple and DC bias, suitable for sustained high-temperature operation.
• Leakage and Dissipation Factor: Leakage current specified at 3670 µA and tanδ (DF) 0.85 measured at 20 °C and 120 Hz for predictable loss behavior.
• Operating Temperature Range: −40 °C to +105 °C, enabling use across a wide thermal range.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General-purpose power supplies: Bulk energy storage and smoothing where high capacitance and substantial ripple handling are required.
• Industrial power electronics: DC-link or intermediate storage in equipment that benefits from screw-terminal mounting for secure electrical and mechanical connections.
• Energy buffering and load support: Systems that need large capacitance to support transient loads or maintain voltage stability during peak demand.

Unique Advantages

• Massive bulk capacitance: 150000 µF delivers large stored energy for applications that require extended hold-up or transient support.
• Robust ripple handling across frequencies: Specified ripple currents at 120 Hz and 100 kHz (10.8 A and 12.42 A) allow designers to address both low- and high-frequency ripple components.
• Secure screw-terminal interface: Radial can with screw terminals provides a durable, low-resistance connection method that simplifies assembly and serviceability.
• High-temperature endurance: Rated for 2000 hours at 105 °C under rated conditions, supporting reliability in thermally demanding installations.
• Wide operating range: −40 °C to +105 °C operation accommodates a broad set of environmental conditions for industrial and general-purpose equipment.
• Regulatory compliance: RoHS compliance supports environmental requirements for modern designs.
