LNT1A684MSEB

The LNT1A684MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering very high capacitance in a robust radial can with screw terminals. Designed for general-purpose applications that require large bulk energy storage, it combines 680,000 µF at 10 V with high ripple current capability and a wide operating temperature range.

This part is built for demanding thermal and ripple environments, rated for operation from −40°C to +105°C with a 2,000 hour endurance at 105°C for the 10 V class, and is available in cardboard-packed quantities for mass production use.

Key Features

• High Capacitance: 680,000 µF (680 mF) rated capacitance provides substantial bulk energy storage and smoothing for low-voltage, high-capacity designs.
• Rated Voltage & Tolerance: 10 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C, enabling predictable performance in design margins.
• Robust Ripple Current Capability: Low-frequency ripple current of 18.4 A (120 Hz) and high-frequency ripple current of 21.16 A (100 kHz) to handle significant AC components under load.
• Thermal Endurance: Operating temperature range −40°C to +105°C with a specified life of 2,000 hours at 105°C for the 10 V rating, and defined post-test limits for capacitance, tan δ and leakage.
• Leakage and Loss Characteristics: Specified leakage current of 5,000 µA and a tangent of loss angle (tan δ) of 2.4 at 20°C, 120 Hz for predictable dissipation and standby behavior.
• Screw Terminal Radial Can Package: φ90 × 170 mm can with screw terminals (terminal pitch 31.8 mm, terminal length 6 mm, nominal bolt M5) for secure mechanical and electrical connections.
• Regulatory & Availability: RoHS compliant and listed as in mass production, packaged in cardboard for shipment and handling.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing where very high capacitance at low voltage is required.
• High-ripple environments — Applicable in designs that require substantial ripple current handling (18.4 A at 120 Hz; 21.16 A at 100 kHz).
• Industrial and electronic equipment — Suited to systems operating across −40°C to +105°C that need long endurance and stable capacitance under DC bias plus ripple.

Unique Advantages

• Substantial bulk storage in a single component: 680,000 µF reduces the need for many parallel devices, simplifying board layout and BOM.
• High ripple tolerance: Rated for high AC ripple at both low and high frequencies, enabling use in power stages with significant switching or ripple currents.
• Screw-terminal reliability: M5 screw terminals and robust radial can construction provide secure electrical and mechanical connections for high-current applications.
• Wide operating temperature range with defined life: −40°C to +105°C operation and a 2,000 hour life at 105°C supports sustained performance in elevated-temperature installations.
• Predictable electrical parameters: Specified tolerance, tan δ, and leakage figures support accurate design trade-offs for filtering and energy storage functions.
• RoHS compliant and production-ready: Environmentally compliant and available in mass production quantities with cardboard packing for efficient procurement.
