LNT1E154MSEB

The LNT1E154MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, designed for general-purpose power electronics. It delivers a very large capacitance (150,000 µF) in a robust radial can with M5 screw terminals for secure, high-current connections.

Engineered for high-ripple, high-temperature environments, this 25 V capacitor offers high low- and high-frequency ripple current capability and a rated endurance of 2000 hours at 105°C, making it suitable for applications that require bulk energy storage and smoothing under sustained thermal stress.

Key Features

• High Capacitance & Rated Voltage — 150,000 µF (150 mF) nominal capacitance at a rated voltage of 25 V, providing substantial bulk energy storage and filtering capacity.
• High Ripple Current Capability — Low-frequency ripple current of 13.8 A (120 Hz) and high-frequency ripple current of 15.87 A (100 kHz), enabling effective handling of AC ripple and switching noise.
• Wide Operating Temperature — Specified for operation from −40°C to +105°C, supporting deployment in elevated-temperature systems.
• Endurance at Elevated Temperature — Rated life of 2000 hours at 105°C under rated ripple conditions, with defined limits for capacitance change, tan δ, and leakage after endurance tests.
• Screw-Terminal, Radial Can Package — φ63.5 × 120 mm can with M5 screw terminals for secure mechanical and electrical connections in high-current layouts.
• Electrical Characteristics — Capacitance tolerance ±20%, tangent of loss angle (tan δ) 0.7 (measured at 20°C, 120 Hz), and leakage current specified at 5000 µA.
• RoHS Compliant & Packaging — RoHS-compliant construction; supplied in cardboard packing for bulk handling.

Typical Applications

• Power supply smoothing — Bulk filtering and hold-up in DC power supplies where high capacitance and ripple handling reduce output ripple and provide energy buffering.
• Power electronics energy storage — Local energy storage in converters and inverters that demand large charge reservoirs and reliable performance at elevated temperatures.
• High-ripple environments — Systems with substantial AC ripple or switching noise benefit from the capacitor’s rated ripple current capability at both low and high frequencies.
• Industrial and general-purpose equipment — General-purpose applications requiring robust, long-life bulk capacitance with screw-terminal mounting for secure installation.

Unique Advantages

• Substantial bulk capacitance: 150,000 µF provides large energy storage in a single discrete component, reducing the need for parallel arrays.
• High ripple current handling: Rated for 13.8 A at 120 Hz and 15.87 A at 100 kHz, enabling effective suppression of both low- and high-frequency ripple.
• Thermal endurance: Rated life of 2000 hours at 105°C offers predictable performance and longevity under sustained high-temperature operation.
• Robust screw-terminal mounting: M5 screw terminals and a radial can package provide a secure, low-impedance connection for high-current applications.
• Measured electrical loss characterization: Specified tan δ (0.7 at 20°C, 120 Hz) and defined leakage current let engineers quantify dissipation and stand-by losses during design.
• Regulatory compliance and packaging: RoHS-compliant construction and cardboard packing support environmental requirements and standard handling practices.
