LNR1C684MSEB

The LNR1C684MSEB is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose power applications. It delivers very large capacitance (680,000 µF) at a rated voltage of 16 V and is built for high ripple-current environments and long endurance.

Key values include high low- and high-frequency ripple handling, a rated lifetime of 5,000 hours at 85 °C, and operation across –40 °C to 85 °C, making it suitable where bulk energy storage and robust smoothing are required within that temperature window.

Key Features

• Very high capacitance: 680,000 µF (680 mF) nominal capacitance provides substantial bulk energy storage for smoothing and decoupling in power systems.
• Rated voltage: 16 V rated working voltage suitable for low-voltage power rails and storage applications requiring large capacitance at this voltage.
• High ripple-current capability: 33 A low-frequency ripple current at 120 Hz and 37.95 A high-frequency ripple current at 100 kHz, enabling handling of significant AC current components.
• Endurance and temperature range: 5,000 hours lifetime at 85 °C and operating range from –40 °C to 85 °C, supporting sustained operation under the specified thermal stress.
• Leakage and dissipation: Specified leakage current up to 5,000 µA and tan δ (DF) = 1.5 measured at 20 °C, 120 Hz, allowing designers to assess leakage and loss for system budgeting.
• Robust mechanical and mounting options: Screw-terminal, radial can package with φ90 × 170 mm body dimensions and standard bracket options for secure installation in larger assemblies.
• Compliance and packaging: RoHS compliant and supplied in cardboard packing for handling and storage.

Typical Applications

• General-purpose power systems: Large-capacitance smoothing and bulk storage where high ripple current handling and long endurance at 85 °C are required.
• Power electronics assemblies: Use in modules that require high bulk capacitance and screw-terminal mounting for secure electrical connection and mechanical stability.
• Industrial equipment: Suitable for general-purpose industrial designs that operate within –40 °C to 85 °C and need extended operational life under rated conditions.

Unique Advantages

• Massive bulk capacitance: 680,000 µF reduces the number of capacitors needed for bulk energy storage, simplifying PCB layout and system BOM.
• High ripple tolerance: Ripple current ratings (33 A at 120 Hz, 37.95 A at 100 kHz) support heavy AC loading and transient duty without immediate degradation.
• Long endurance at elevated temperature: 5,000 hours at 85 °C provides predictable lifetime performance for designs with sustained thermal stress.
• Screw-terminal reliability: Radial can with screw terminals and standard mounting brackets enables secure electrical connections and robust mechanical mounting in larger enclosures.
• Clear electrical characterization: Specified leakage current and tan δ values measured at 20 °C, 120 Hz allow straightforward engineering trade-offs for efficiency and charge retention.
• RoHS compliant: Conforms to RoHS requirements for material compliance in regulated markets.
