LNT1E683MSEN

The Nichicon LNT1E683MSEN is a screw‑terminal, large‑can aluminum electrolytic capacitor providing 68 mF (68,000 µF) of capacitance at a rated voltage of 25 V. It is a polarized, general‑purpose power electrolytic designed for high ripple current and bulk energy storage in industrial and power‑electronics applications.

With a rated temperature range of −40°C to +105°C, a 2,000‑hour endurance at 105°C, and high low‑ and high‑frequency ripple current capability, this capacitor targets designs that require robust bulk filtering, smoothing and energy buffering with secure screw‑terminal connections.

Key Features

• Capacitance & Voltage — 68 mF (68,000 µF) nominal capacitance with a rated voltage of 25 V and a capacitance tolerance of −20% to +20%.
• High Ripple Current Capability — Supports 10.2 A at 120 Hz (low frequency) and 11.73 A at 100 kHz (high frequency), enabling effective handling of sustained AC ripple and switching currents.
• Endurance at Elevated Temperature — Rated life of 2,000 hours at +105°C under rated ripple conditions, providing predictable performance in higher‑temperature environments.
• Low‑frequency loss and leakage — Specified tangent of loss angle (tan δ) of 0.5 (measured at 20°C, 120 Hz) and a leakage current of 3,910 µA for reliable electrical behavior.
• Screw‑Terminal, Large‑Can Package — Radial can with screw terminals (φ51 × 120L; L: 12 cm × D: 5.1 cm) for secure, high‑current wiring and mechanical robustness in equipment racks and power assemblies.
• Regulatory & Production — RoHS compliant, packaged in cardboard packing and available in mass production quantities.

Typical Applications

• Power Supply Bulk Filtering — High capacitance and strong ripple current ratings make the LNT1E683MSEN suitable for bulk smoothing and energy storage on DC power rails.
• Inverters and UPS Systems — Screw‑terminal connection and high ripple capability support DC link and energy buffering roles in inverter and uninterruptible power supply designs.
• Industrial Power Electronics — Durable operation to +105°C and robust leakage/tan δ characteristics benefit motor drives and industrial power modules requiring reliable bulk capacitance.
• Telecom and DC Power Systems — Large capacitance and sustained ripple handling help stabilize supply rails and absorb transient loads in DC distribution systems.

Unique Advantages

• Substantial Bulk Energy Storage: 68 mF (68,000 µF) provides large charge reservoir for smoothing and transient support in high‑energy designs.
• High Ripple Handling: Rated 10.2 A (120 Hz) and 11.73 A (100 kHz) ripple currents enable continuous operation under heavy AC and switching loads.
• Secure Screw‑Terminal Connectivity: Robust screw terminals and a large‑can package simplify high‑current wiring and improve mechanical stability in assemblies.
• Designed for Elevated Temperatures: −40°C to +105°C operating range with 2,000 hours endurance at 105°C supports demanding thermal environments.
• Measurable Electrical Characteristics: Specified tan δ (0.5 at 20°C, 120 Hz) and defined leakage current (3,910 µA) allow predictable selection and engineering margining.
• Production & Compliance: RoHS compliant and supplied in cardboard packing, with product available in mass production quantities for volume designs.
