LNT1H103MSEN

The LNT1H103MSEN is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for general‑purpose power applications. It provides a large 10,000 µF capacitance at a 50 V rating with a robust screw‑terminal package for secure high‑current connections.

Engineered for elevated operating conditions, the LNT1H103MSEN offers defined dissipation characteristics and high ripple‑current capability, with a -40 °C to 105 °C operating range and a manufacturer‑specified 2000‑hour endurance at 105 °C. The part is RoHS compliant and supplied in cardboard packing for production use.

Key Features

• Capacitance & Voltage: 10,000 µF nominal capacitance at a 50 V rated voltage with tolerance -20% to +20% for bulk energy storage and smoothing applications.
• High ripple‑current capability: Low‑frequency ripple current 4.9 A (120 Hz) and high‑frequency ripple current 5.635 A (100 kHz), enabling effective handling of AC stress in power circuits.
• Dissipation and leakage: Tangent of loss angle (tanδ) 0.25 measured at 20 °C, 120 Hz and a specified leakage current of 2120 µA for predictable electrical behavior.
• Thermal and endurance rating: Operating temperature range –40 °C to +105 °C with a rated life/endurance of 2000 hours at 105 °C under specified conditions.
• Mechanical & mounting: Screw terminal radial can package, size φ35 × 80 mm length, providing secure, low‑resistance connections for power wiring.
• Compliance & production: RoHS compliant, supplied in cardboard packing, and listed as mass production status.

Typical Applications

• Industrial power supplies: Bulk smoothing and hold‑up capacitance where 10,000 µF and high ripple current capability reduce voltage ripple under heavy load.
• Power conversion modules: Screw‑terminal mounting and high ripple performance suit DC‑link or intermediate storage in power conversion stages.
• Backup and energy‑hold applications: Large capacitance provides short‑term energy storage for hold‑up and transient buffering in general‑purpose equipment.
• General‑purpose power electronics: Designed for equipment requiring robust, removable connections and predictable electrical dissipation at elevated temperatures.

Unique Advantages

• High bulk capacitance at 50 V: 10,000 µF delivers substantial energy storage for smoothing and transient control in DC systems.
• Measured ripple performance: Specified ripple currents at both low and high frequencies (4.9 A @120 Hz; 5.635 A @100 kHz) support thermal budgeting and reliability planning.
• Specified dissipation and leakage figures: tanδ (0.25 @20 °C, 120 Hz) and leakage current (2120 µA) provide verifiable parameters for circuit design and loss calculations.
• Designed for elevated operating temperatures: Rated to 105 °C with a 2000‑hour endurance at that temperature, enabling deployment in thermally demanding environments.
• Secure screw‑terminal connections: Radial can with screw terminals simplifies high‑current wiring and replacement in field or factory settings.
• Production‑ready and compliant: RoHS compliance and cardboard packing reflect readiness for volume production and regulatory adherence.
