LNR1K154MSEB

The LNR1K154MSEB from Nichicon is an aluminum electrolytic, screw-terminal capacitor in the LNR series designed for general-purpose power applications. It delivers very high bulk capacitance (150,000 µF) at an 80 V rated voltage with a screw-terminal radial can package optimized for robust electrical and mechanical connections.

This capacitor targets designs that require large energy storage, high ripple current handling and long operating life at elevated temperatures — providing defined endurance, leakage and loss characteristics for reliable system-level performance.

Key Features

• High Capacitance & Voltage: 150,000 µF nominal capacitance at an 80 V rated voltage for substantial bulk energy storage.
• Tolerance: ±20% capacitance tolerance (measured at 120 Hz, 20°C) for predictable system design margins.
• High Ripple Current Capability: 26.5 A at 120 Hz (low frequency) and 30.48 A at 100 kHz (high frequency) to support heavy AC ripple and pulse loads.
• Loss Characteristic: tanδ (dissipation factor) 0.4 measured at 20°C and 120 Hz for defined internal losses.
• Leakage Current: Specified leakage current of 5000 µA for initial performance characterization.
• Endurance: 5000 hours at 85°C under rated conditions; after endurance test, capacitance remains within ±15%, tanδ within 175% of initial spec, and leakage current remains at or below initial specified value.
• Operating Temperature Range: −40°C to +85°C to accommodate a wide range of thermal environments.
• Rugged Package & Mounting: Radial can with screw terminals and bracket options for secure mounting; supplied in cardboard packing and available in mass production.
• RoHS Compliant: Meets RoHS requirements as stated in the product data.

Typical Applications

• Power Supply Bulk Storage: Provides high-capacitance bulk energy storage to smooth DC bus voltage and support transient load currents.
• Industrial Power Electronics: Suitable where sustained high ripple current and long endurance are required for converters, inverters, and motor drives.
• UPS and Energy Storage Subsystems: Useful for systems needing large capacitance and defined endurance at elevated temperatures.

Unique Advantages

• Large Stored Energy in a Compact Form: 150,000 µF at 80 V offers substantial bulk capacitance for designs that must minimize ripple and hold-up time without adding many parallel caps.
• High Ripple Handling: Specified low- and high-frequency ripple currents (26.5 A @120 Hz; 30.48 A @100 kHz) reduce thermal stress in high-power applications.
• Defined Endurance Performance: 5000 hours at 85°C with clear post-test limits on capacitance, tanδ and leakage simplifies lifetime planning and reliability analysis.
• Screw-Terminal Mechanical Reliability: Radial can with screw terminals and mounting brackets provides a robust electrical and mechanical interface for high-current connections.
• predictable Loss and Leakage: Specified tanδ and leakage current values enable accurate thermal and power-loss budgeting in system design.
• Regulatory Compliance: RoHS compliance supports use in regions and projects requiring restricted substance adherence.
