LNT1E683MSEB

The LNT1E683MSEB is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNT series. It delivers 68 000 µF (68 mF) of capacitance at a 25 V rating in a radial can with screw terminals, intended for general‑purpose applications requiring high bulk capacitance and robust ripple handling.

Designed for operation from −40 °C to +105 °C with a rated endurance of 2 000 hours at +105 °C, this part provides high ripple current capability and controlled leakage and loss characteristics for reliable performance in production systems. The part is RoHS compliant and available in mass production with cardboard packing.

Key Features

• High Capacitance & Voltage: 68 000 µF nominal capacitance at a 25 V rated voltage, ±20% tolerance for bulk energy storage and decoupling in general‑purpose circuits.
• Robust Ripple Performance: 10.2 A low‑frequency ripple current (120 Hz) and 11.73 A high‑frequency ripple current (100 kHz) to support demanding AC ripple conditions.
• Controlled Loss and Leakage: Tangent of loss angle (tan δ) 0.5 at 20 °C, 120 Hz and a measured leakage current of 3 910 µA, enabling predictable impedance and standby characteristics.
• Screw Terminal Package: Radial can with screw terminals (φ51 body), compatible with M5 bolts per the LNT series terminal specifications for secure mechanical and electrical connections.
• Operating Temperature & Endurance: Rated for −40 °C to +105 °C with 2 000 hours life at +105 °C under rated ripple and DC bias (endurance specified by the LNT series for 10–250 V parts).
• Boardroom to Production Ready: Size φ51 × 120L (L: 12 × D: 5.1 cm), supplied in cardboard packing and listed as mass production status for volume use.
• Regulatory: RoHS compliant, consistent with the environmental status documented for the part.

Typical Applications

• General‑purpose power electronics — Provides bulk capacitance and high ripple current handling for general‑purpose circuits and assemblies.
• Power smoothing and filtering — Large capacitance and specified ripple ratings support smoothing of DC outputs and filtering in power rails.
• Energy buffering in stationary equipment — Useful where sizeable charge storage and discharge capability are needed within a defined temperature and life profile.

Unique Advantages

• Significant bulk capacitance: 68 000 µF provides substantial energy reserve in a single component, reducing the need for multiple parallel capacitors.
• High ripple capability: Rated ripple currents at both low and high frequencies accommodate varied ripple spectra without exceeding component limits.
• Temperature and endurance specification: Rated to −40 °C to +105 °C with 2 000‑hour endurance at +105 °C, allowing predictable performance under elevated temperature and ripple stress.
• Screw‑terminal reliability: M5‑compatible screw terminals and a radial can package deliver secure electrical and mechanical connections for production assemblies.
• Verified loss and leakage metrics: Specified tan δ and measured leakage current give clear electrical expectations for design margining and thermal management.
• Production readiness: Mass production status and cardboard packing support procurement and assembly workflows for volume applications.
