LNT1A684MSE

The LNT1A684MSE from Nichicon is a screw‑terminal, radial aluminum electrolytic capacitor providing 680000 µF (680 mF) nominal capacitance at 10 V. Designed for general‑purpose power systems, it delivers large bulk capacitance and high ripple current capability in a rugged screw‑terminal can.

Key attributes include a wide operating temperature range of −40°C to +105°C, a rated endurance of 2000 hours at 105°C, and RoHS compliance—making it suitable for demanding industrial and power electronics designs that require reliable energy buffering and smoothing.

Key Features

• Bulk Capacitance — 680000 µF nominal capacitance provides substantial energy storage for bulk filtering and DC link applications.
• Rated Voltage — 10 V rated voltage appropriate for low‑voltage power rails and energy buffer circuits.
• High Ripple Current — Low‑frequency ripple current of 18.4 A (120 Hz) and high‑frequency ripple current of 21.16 A (100 kHz) support continuous ripple handling in power supplies and converters.
• Endurance & Temperature — Rated life of 2000 hours at 105°C and operating range from −40°C to +105°C for robust thermal performance under sustained load.
• Electrical Characteristics — Capacitance tolerance −20% to +20% and polarized construction; leakage current specified at 5000 µA.
• Package & Mounting — Radial can with screw terminals (φ90 × 170L size, nominal L: 17 × D: 9 cm) for secure bolted connections and straightforward mechanical installation.
• Compliance & Supply — RoHS compliant and available in mass production quantities; packaged in cardboard packing.

Typical Applications

• General Power Filtering — Provides large capacitance for smoothing bulk DC rails and reducing voltage ripple in general‑purpose power supplies.
• Energy Buffering — Acts as a local energy reservoir in systems requiring transient load support and decoupling at low voltage rails.
• Industrial Power Electronics — Suitable for industrial converters and power modules where high ripple current capability and robust screw‑terminal connections are required.
