LNT2D103MSEB

The LNT2D103MSEB from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNT series, offering 10,000 µF capacitance at a 200 V rating. Designed for general-purpose power applications, it provides high bulk capacitance with screw-terminal mounting for secure, low-impedance electrical and mechanical connections.

Key value comes from its combination of high capacitance, substantial ripple-current capability, and 105°C endurance, making it suitable for demanding power-electronics environments that require robust energy storage and smoothing.

Key Features

• Capacitance and Voltage — 10,000 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance for bulk energy storage and smoothing.
• High Ripple Current — Rated low-frequency ripple current of 8.2 A at 120 Hz and high-frequency ripple current of 9.84 A at 100 kHz for effective handling of AC ripple across a wide frequency range.
• Endurance at Elevated Temperature — Rated life of 2,000 hours at +105°C when subjected to rated ripple and DC bias, supporting high-temperature operation in industrial systems.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz, giving a defined dissipation characteristic for thermal and loss budgeting.
• Leakage Current — Specified leakage current of 4,240 µA after application of rated voltage, useful for design margin and power-loss calculations.
• Robust Screw-Terminal Package — Radial can with screw terminals (φ76.2 × 120 mm length) and M5 bolt nominal terminal for secure bolted connections and mechanical stability.
• Operating Range and Compliance — Temperature range −25°C to +105°C and RoHS compliant; supplied in cardboard packing and currently in mass production.

Typical Applications

• Power Supply Bulk Storage — Provides large-capacitance energy storage and smoothing for high-voltage DC bus and offline power supplies where 200 V rating and 10,000 µF are required.
• Industrial Power Electronics — Suited for inverter and motor-drive subsystems that need high ripple-current handling and robust screw-terminal connections for reliable field wiring.
• UPS and Energy Backup — Acts as bulk filter and hold-up capacitor in uninterruptible power supplies and backup systems, leveraging high capacitance and 105°C endurance.

Unique Advantages

• Large Stored Energy Density: 10,000 µF at 200 V delivers substantial bulk capacitance for smoothing, hold-up, and DC-bus stabilization without parallel arrays.
• High Ripple Capability: 8.2 A (120 Hz) and 9.84 A (100 kHz) ripple ratings reduce the need for extra parallel capacitors to manage ripple heating and lifetime stress.
• High-Temperature Endurance: 2,000-hour life at 105°C under rated ripple and DC bias supports reliable operation in hot industrial environments.
• Secure Mechanical and Electrical Mounting: Screw-terminal radial can with M5 nominal bolt pitch provides durable, low-impedance connections for high-current installations.
• Clear Loss and Leakage Specs: Specified tan δ (0.2 at 20°C/120 Hz) and leakage current (4,240 µA) enable predictable thermal and power-loss design decisions.
• RoHS Compliant and Production-Ready: RoHS conformity and mass-production status simplify procurement and regulatory alignment.
