LNT1A683MSEB

The LNT1A683MSEB is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require very high bulk capacitance at low voltage. It delivers 68,000 µF at 10 V in a radial can with screw terminals, offering robust electrical performance and secure mechanical connections for assemblies that demand high ripple handling and long-term stability.

Key design characteristics include a wide operating temperature range of −40°C to +105°C, rated life of 2,000 hours at 105°C (for the 10 V rating), and high ripple-current capability at both low and high frequencies—making it suitable where bulk energy storage and stable DC filtering are required.

Key Features

• High Capacitance: 68,000 µF nominal capacitance provides substantial bulk energy storage for smoothing and decoupling in low-voltage systems.
• Rated Voltage: 10 V DC rating appropriate for low-voltage power rails and storage applications.
• Screw Terminal Mounting: Radial can with screw terminals (φ51 case) for secure bolt connections; nominal bolt size M5 for φ51 dimensions as specified in the series documentation.
• High Ripple Current Capability: Low-frequency ripple current 6.8 A at 120 Hz and high-frequency ripple current 7.82 A at 100 kHz, supporting demanding AC ripple environments.
• Thermal Endurance: Rated for operation from −40°C to +105°C with a specified load life of 2,000 hours at 105°C for the 10 V rating.
• Electrical Loss and Tolerance: Tangent of loss angle (tan δ) 0.8 (measured at 20°C, 120 Hz) and capacitance tolerance −20% to +20%.
• Leakage Current: Specified leakage current of 2,470 µA (after 5 minutes’ application of rated voltage as per product data).
• RoHS Compliant: Meets applicable RoHS requirements as indicated in product documentation.

Typical Applications

• General-purpose power filtering: Large bulk capacitance and high ripple-current ratings make this capacitor suitable for smoothing and decoupling on low-voltage DC rails.
• Energy storage in low-voltage systems: Provides short-term energy buffering where high capacitance at 10 V is required.
• Industrial power assemblies: Screw-terminal packaging and robust mechanical fastening support secure installation in machinery and power distribution modules.

Unique Advantages

• Substantial bulk capacitance: 68,000 µF enables reduced component count for large-capacitance needs and simplifies power supply filtering designs.
• Strong ripple handling: 6.8 A (120 Hz) and 7.82 A (100 kHz) ripple-current ratings allow reliable operation under varying ripple conditions.
• Designed for elevated temperatures: Rated life of 2,000 hours at 105°C ensures predictable performance in high-temperature environments for this voltage class.
• Secure electrical and mechanical connection: Screw-terminal construction with M5 nominal bolt provision (φ51) provides low-resistance connections and robust mounting.
• Measurable loss characteristics: Specified tan δ (0.8 at 20°C, 120 Hz) and defined leakage current permit straightforward design margining and thermal management.
