LNT1K103MSE

The LNT1K103MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series designed for high-voltage, high-capacitance power applications. It delivers 10,000µF at a rated voltage of 80V in a robust radial can with screw terminals, providing a polarized solution for bulk energy storage, smoothing and decoupling in industrial and power-electronics systems.

Engineered for sustained operation up to 105°C, the LNT1K103MSE targets general-purpose power designs that require high ripple-handling capability and long operational life under elevated temperature and DC bias conditions.

Key Features

• High Capacitance — 10,000µF (10 mF) nominal capacitance for bulk energy storage and smoothing in power rails.
• Rated Voltage — 80 VDC rating suitable for higher-voltage DC bus and power-supply applications.
• Screw-Terminal Mounting — Radial can with screw terminals enables secure, low-impedance connections for high-current paths and easy field wiring.
• High Ripple Current Capability — Rated ripple current of 5.4 A at 120 Hz (low frequency) and 6.21 A at 100 kHz (high frequency) to support substantial AC load components.
• Endurance at Elevated Temperature — Rated for 2,000 hours at 105°C under rated ripple and bias for reliable long-term operation in hot environments.
• Polarized Design & Tolerance — Polar capacitor with capacitance tolerance ±20% (measured at 120 Hz, 20°C); loss tangent (tan δ) specified at 0.2.
• Leakage Current — Specified leakage current of 2,680 µA (measured condition as provided), suitable for power applications where self-discharge is acceptable.
• Compact, Serviceable Package — φ51 × 80 mm can (D: 5.1 cm × L: 8.0 cm) with mounting options for reliable mechanical installation; supplied in cardboard packing for handling and shipping.
• RoHS Compliant — Meets RoHS requirements as indicated in product documentation.

Typical Applications

• Power Supplies — Bulk smoothing and hold-up on DC bus rails where 80 V and high capacitance are required.
• Inverters and Motor Drives — Energy buffering and ripple attenuation on intermediate DC links that demand high ripple current capability.
• Industrial Power Electronics — Decoupling and energy storage in converters and control systems exposed to elevated temperatures (up to 105°C).
• UPS and Backup Systems — Bulk storage to sustain short-term hold-up and provide stable DC under load transients.

Unique Advantages

• Large Stored Energy Capacity: 10,000µF at 80 V provides substantial energy density for smoothing and hold-up functions.
• Robust Ripple Handling: Dual ripple ratings (5.4 A @ 120 Hz and 6.21 A @ 100 kHz) support both low- and high-frequency ripple scenarios common in modern power systems.
• High-Temperature Endurance: Rated 2,000 hours at 105°C under rated conditions, enabling reliable performance in thermally demanding installations.
• Secure, Low-Inductance Termination: Screw-terminals permit mechanically solid, low-resistance connections for high-current applications and simplify field wiring.
• Clear Specification Set: Defined tan δ (0.2), leakage current (2,680 µA), and ±20% tolerance allow predictable design margining and component selection.
• RoHS Compliance and Production Availability: RoHS-compliant and in mass production, supporting consistent supply and regulatory alignment.
