LNT1A684MSEN

The LNT1A684MSEN is a screw‑terminal type aluminum electrolytic capacitor from Nichicon’s LNT series, specified at 680000 µF (680 mF) and 10 V. It is designed for general‑purpose power applications that require large capacitance, secure screw‑terminal connections and sustained performance in elevated temperatures.

Key value propositions include very high capacitance for bulk energy storage, substantial ripple current capability, and a rated operating range of –40 °C to +105 °C with a specified load life at elevated temperature.

Key Features

• Large Capacitance: 680000 µF (680 mF) provides significant bulk energy storage for filtering and smoothing in power systems.
• Rated Voltage: 10 V nominal rating suited for low‑voltage power rails and DC bus applications.
• High Ripple Current Capability: Rated ripple current of 18.4 A at 120 Hz and 21.16 A at 100 kHz to support high AC stress in power conversion and filtering circuits.
• Screw Terminal Mounting: Radial can with screw terminals for robust, low‑impedance connections and secure mechanical attachment.
• Broad Temperature Range: Operating temperature from –40 °C to +105 °C to accommodate demanding thermal environments.
• Endurance and Shelf Life: Load life specified as 2000 hours at 105 °C (for 10 V ratings) with capacitance change within ±20% and leakage current meeting initial specified limits after endurance testing.
• Physical Size: Dimension φ90 × 170L (SizeDimension L: 17 x D: 9 cm) suitable for systems that can accommodate a large, high‑energy capacitor.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk energy storage and smoothing on low‑voltage DC rails where large capacitance and high ripple current handling reduce voltage ripple and improve regulation.
• Industrial Power Electronics: DC link and filtering in inverters, converters and motor drive systems that require secure screw‑terminal connections and high ripple endurance.
• Backup and UPS Systems: Energy buffering and hold‑up capacitance to support short‑term power continuity in systems with constrained space for large capacitors.

Unique Advantages

• Massive Capacitance Density: 680000 µF at 10 V enables substantial energy storage in a single component, simplifying BOM and reducing the need for parallel capacitor banks.
• Designed for High AC Stress: Explicit ripple current ratings at both 120 Hz and 100 kHz provide predictable performance for power conversion and filtering across frequency ranges.
• Robust Mechanical and Electrical Termination: Screw‑terminal construction offers low‑resistance, secure connections for high‑current applications and easier assembly in industrial environments.
• Elevated‑Temperature Endurance: Specified load life of 2000 hours at +105 °C for 10 V parts, with defined limits on capacitance change and leakage after testing, supporting long‑term reliability planning.
• Wide Operating Temperature: –40 °C to +105 °C operation supports deployment in a broad range of ambient conditions.
• Regulatory Compliance: RoHS conformity simplifies environmental compliance for product builds and supply chains.
