LNT1C684MSEN

The LNT1C684MSEN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNT series, delivering 680,000 µF (680 mF) at a rated voltage of 16 V. Designed for general-purpose use, this part combines very large capacitance with high ripple-current capability and a screw-terminal can-style package for secure, low-impedance connections.

Key value propositions include high bulk energy storage, high ripple-current handling (measured at both low and high frequencies), a wide operating temperature range from −40°C to +105°C, and a rated endurance of 2,000 hours at 105°C.

Key Features

• Very Large Capacitance — 680,000 µF (680 mF) nominal capacitance with ±20% tolerance for substantial bulk energy storage and smoothing.
• Rated Voltage — 16 V nominal rated voltage suited to low-voltage power systems.
• High Ripple-Current Capacity — Low-frequency ripple current 24 A (120 Hz) and high-frequency ripple current 27.6 A (100 kHz) to support demanding AC ripple environments.
• Screw Terminal Package — Radial can with screw terminals for robust electrical and mechanical connections in heavier-current applications.
• Thermal and Endurance Specs — Operating temperature −40°C to +105°C with an endurance rating of 2,000 hours at 105°C (per part data).
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) specified as 2 (measured at 20°C, 120 Hz) and leakage current listed at 5,000 µA.
• Packaging and Availability — Supplied in cardboard packing and currently in mass production.
• RoHS Compliant — Meets RoHS requirements as indicated in product information.

Typical Applications

• General purpose — For systems requiring very large bulk capacitance with screw-terminal mounting for secure, high-current connections.
• High-ripple environments — Where sustained ripple handling is required: specified at 24 A (120 Hz) and 27.6 A (100 kHz).
• Elevated-temperature operation — Applications operating within −40°C to +105°C that require a capacitor rated for 2,000 hours at 105°C.

Unique Advantages

• Massive bulk capacitance: 680,000 µF provides substantial energy storage and smoothing in low-voltage power designs.
• High ripple capability: Rated ripple currents at both low and high frequencies reduce heating and extend operational stability under ripple stress.
• Screw-terminal reliability: Robust radial can with screw terminals enables secure, low-impedance connections for high-current paths.
• Thermal endurance: Rated for −40°C to +105°C with a specified 2,000-hour life at 105°C to support extended duty in elevated-temperature environments.
• Measured electrical characteristics: Specified tan δ and leakage current values (tan δ = 2 at 20°C/120 Hz; leakage = 5,000 µA) allow for predictable design margins.
• Production-ready supply: Cardboard-packed and in mass production for straightforward procurement and BOM planning.
