LNT1K104MSEB

The LNT1K104MSEB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, designed for general-purpose power applications requiring very high capacitance and robust ripple handling. It is a 100000 µF (100 mF), 80 V polarized can-type capacitor rated for operation from −40°C to +105°C with a 2000-hour endurance at 105°C.

Built on the LNT series platform (screw terminal type, 105°C standard), this part combines high capacitance, substantial low- and high-frequency ripple current capability, and a secure screw-terminal mounting for reliable high-current connections.

Key Features

• High Capacitance — 100000 µF (100 mF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C, suitable for large energy-storage and smoothing needs.
• 80 V Rated Voltage — Rated for 80 V DC operation to support higher-voltage power rails within the LNT series voltage range.
• Robust Ripple Current Capability — 18600 mA (18.6 A) at 120 Hz (low frequency) and 21390 mA (21.39 A) at 100 kHz (high frequency), enabling effective AC ripple handling across frequency ranges.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.4 (DF) measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 5000 µA after rated voltage application, allowing designers to budget for standby and leakage behavior.
• Endurance and Temperature — Rated endurance of 2000 hours at 105°C and continuous operation from −40°C to +105°C for high-temperature robustness in demanding environments.
• Screw Terminal Mounting — Radial can with screw terminals for secure mechanical and electrical connection, suitable for high-current bus connections.
• Form Factor and Packaging — Large φ90 × 170L can size with dimensions L: 17 × D: 9 cm; supplied in cardboard packing and available in mass production quantities.
• RoHS Compliant — Meets RoHS requirements as stated in the product information.

Typical Applications

• General-purpose power systems — Used where very high bulk capacitance and high ripple capability are required to support power rails and smoothing tasks.
• High-current DC bus filtering — Screw-terminal mounting and high ripple ratings make the part suitable for applications that need secure, high-current connections and effective AC ripple absorption.
• Energy storage and buffering — Large capacitance supports transient buffering and energy storage in industrial and equipment-level power electronics.

Unique Advantages

• Large stored energy capacity — 100000 µF nominal capacitance reduces the number of parallel components required for high-capacitance designs.
• Wide operating temperature range — −40°C to +105°C rating and 2000-hour endurance at 105°C deliver operational stability in thermally demanding installations.
• High ripple tolerance across frequencies — Specified ripple current at both 120 Hz and 100 kHz supports performance in mixed-frequency environments.
• Secure screw-terminal connections — Mechanical and electrical robustness for high-current bus implementations and easy assembly with bolted connections.
• Manufacturing readiness — Cardboard-packed, mass-production availability supports volume procurement and deployment.
• Regulatory compliance — RoHS compliance for compatibility with regulated product lines and regional requirements.
