LNR1K104MSEN

The LNR1K104MSEN from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNR series, offering 100,000 µF capacitance at an 80 V rating. Its radial can with screw terminals and large-diameter body (φ76.2 × 140 mm) is intended for general‑purpose power applications that require substantial bulk capacitance and secure connections.

Key strengths include high ripple current capability (21.3 A at 120 Hz / 24.5 A at 100 kHz), a wide operating temperature range from −40 °C to 85 °C, and a rated endurance of 5,000 hours at 85 °C, making it suitable where sustained energy storage and thermal robustness are required.

Key Features

• High Capacitance: 100,000 µF (100 mF) for significant bulk energy storage and smoothing in power rails.
• Rated Voltage: 80 V DC rating for higher-voltage power systems within the LNR series range.
• Screw Terminal Package: Radial can with screw terminals provides secure, low‑impedance connections suited to heavy-current wiring and mechanical stability.
• High Ripple Current Handling: Low‑frequency ripple current 21.3 A at 120 Hz and high‑frequency ripple current 24.5 A at 100 kHz to support sustained AC ripple and switching applications.
• Endurance and Reliability: Designed for 5,000 hours at 85 °C under DC bias plus rated ripple current, with specified limits on capacitance change, tan δ, and leakage current after life test.
• Leakage and Loss Characteristics: Specified leakage current up to 5,000 µA and tan δ of 0.35 (measured at 20 °C, 120 Hz), enabling predictable performance characterization.
• Operating Temperature Range: −40 °C to 85 °C, allowing deployment across a wide range of environmental conditions.
• Physical Dimensions: Body diameter φ76.2 mm, length 140 mm (L: 14.0 × D: 7.62 cm), supplied in cardboard packing for mass production handling.
• Regulatory Status: RoHS compliant.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing where a high capacitance and 80 V rating are required.
• Industrial power supplies — DC link and filter capacitors benefiting from high ripple current capability and screw‑terminal connections for robust wiring.
• Backup and UPS systems — Energy reservoir for short‑term hold‑up and peak load support within the specified temperature and endurance limits.

Unique Advantages

• Substantial energy density: 100,000 µF at 80 V provides large bulk capacitance in a single component, reducing part count for energy storage needs.
• High ripple tolerance: Rated ripple currents at both low and high frequencies minimize thermal stress during heavy AC ripple or switching events.
• Secure screw‑terminal mounting: Screw terminals enable reliable, low‑resistance connections for high‑current systems and simplify mechanical installation.
• Defined long‑term performance: 5,000‑hour endurance at 85 °C with specified limits on capacitance change, tan δ, and leakage current supports predictable lifecycle planning.
• Wide service temperature: −40 °C to 85 °C accommodates a broad range of operating environments without additional qualification notes.
• RoHS compliance: Meets regulatory restrictions for lead and other hazardous substances.
