LNT2A683MSE

The LNT2A683MSE is a screw‑terminal aluminum electrolytic capacitor designed for robust DC energy storage and filtering in general‑purpose industrial and power applications. It delivers 68,000 µF (68 mF) at a 100 V rating in a heavy‑duty radial can with screw terminals for high‑current, serviceable connections.

Engineered for elevated operating temperatures, the device is specified for −40 °C to +105 °C and a rated endurance of 2,000 hours at 105 °C under rated ripple conditions, making it suitable for demanding power systems that require large bulk capacitance and reliable ripple handling.

Key Features

• Capacitance & Voltage: 68 mF nominal capacitance at a 100 V rated voltage—provides substantial bulk energy storage for DC bus and smoothing applications.
• Tight Specification Set: Capacitance tolerance ±20% at 120 Hz/20 °C and tan δ specified (0.3 at 20 °C, 120 Hz) for predictable impedance and loss characteristics.
• High Ripple Current Capability: Low‑frequency ripple current of 18.2 A (120 Hz) and high‑frequency ripple current of 20.93 A (100 kHz) to support continuous filtering and decoupling under varying switching conditions.
• Leakage & Endurance: Specified leakage current of 5,000 µA and rated for 2,000 hours at 105 °C with DC bias plus rated ripple current (per series endurance conditions for 10–250 V range).
• Temperature Performance: Operating range from −40 °C to +105 °C with endurance data provided at 105 °C, supporting elevated‑temperature system environments.
• Screw Terminal Package: Radial can with screw terminals (φ90 × 170L casing). Nominal bolt size for φ90 terminals is M5, enabling secure, high‑current mechanical connections and easy servicing.
• Packaging & Production: Cardboard packing and mass production availability for volume procurement and assembly workflows.
• RoHS Compliance: Product is RoHS compliant as supplied.

Typical Applications

• Power Supply Bulk Filtering: Large capacitance and high ripple current capability make it suitable for smoothing DC bus voltages and absorbing energy transients in power supplies.
• Inverter and Motor Drive DC Link: Screw‑terminal connection and high ripple handling support DC‑link and intermediate‑bus energy storage in industrial drive systems.
• Industrial Power Electronics: Provides stable bulk storage and filtering in UPS, power conversion, and industrial control equipment operating at elevated temperatures.

Unique Advantages

• Large Energy Density at 100 V: 68 mF of capacitance enables significant bulk energy storage in a single radial can, reducing the number of parallel components required.
• Robust Ripple Handling: Both low‑frequency and high‑frequency ripple current ratings (18.2 A @120 Hz, 20.93 A @100 kHz) support mixed switching environments and reduce thermal stress.
• Serviceable, High‑Current Termination: Screw‑terminal design with M5 nominal bolt for φ90 cases provides durable, low‑impedance connections and simplifies maintenance or replacement.
• High‑Temperature Endurance: Rated for operation to 105 °C with a defined 2,000‑hour endurance at that temperature under rated ripple, supporting long‑term operation in hot enclosures.
• Predictable Electrical Behavior: Specified tan δ and ±20% capacitance tolerance at 120 Hz/20 °C give designers quantifiable impedance and loss metrics for system-level modeling.
• Manufacturing‑Ready Supply: Cardboard packing and mass production status help streamline procurement and integration into volume builds.
