LNT2H103MSEJBN

The LNT2H103MSEJBN from Nichicon is a screw‑terminal aluminum electrolytic capacitor providing 10,000 µF capacitance at up to 500 V. It is a polarized, radial can style capacitor designed for general‑purpose power applications that require high capacitance, high ripple current capability and robust thermal endurance.

Key value propositions include high voltage handling (500 V), rated operation up to 105°C, and screw‑terminal mounting for secure electrical and mechanical connections in industrial and power systems where a durable bulk capacitor is required.

Key Features

• Electrical Capacity: 10,000 µF nominal capacitance with tolerance ±20% (−20% to +20%), delivering substantial bulk energy storage for DC systems.
• High Voltage Rating: Rated voltage of 500 V to support high‑voltage power rails and large DC bus applications.
• High Ripple Current: Rated ripple current of 29.9 A at 120 Hz and 41.86 A at 100 kHz, enabling effective smoothing under heavy AC/rectified loads.
• Thermal Performance: Designed for operation from −25°C to +105°C, suitable for elevated ambient temperature environments within the specified range.
• Endurance / Load Life: Load life specified as 2,000 hours at 105°C under rated ripple current conditions for 500 V parts (per the series datasheet).
• Mounting & Package: Screw terminal radial can package for secure, low‑impedance connections and easy installation; package case listed as radial, can with screw terminals.
• Polarized Type: Polarized electrolytic construction—observe polarity during installation.
• Compliance: RoHS compliant, meeting applicable restrictions on hazardous substances.
• Physical Size: Size dimension noted as L: 25 × D: 9 cm, for mechanical planning and bracket design.

Typical Applications

• General‑purpose power filtering: Used where large bulk capacitance and high voltage are required to smooth DC rails and reduce ripple under load.
• Energy storage for power electronics: Provides bulk charge storage and transient energy support in high‑voltage circuits that require secure screw‑terminal connections.
• Industrial power systems: Suitable for systems that demand capacitor endurance at elevated temperatures (up to 105°C) and sustained ripple handling.

Unique Advantages

• High voltage capability: 500 V rating allows integration into higher‑voltage DC buses without stepping down system voltage.
• Robust ripple performance: Specified ripple currents at both low and high frequencies (29.9 A at 120 Hz, 41.86 A at 100 kHz) help maintain performance under continuous rectified or switching stress.
• Elevated temperature endurance: Rated for operation to 105°C with a documented load life of 2,000 hours at that temperature for 500 V parts, supporting reliable operation in warm environments.
• Screw‑terminal mounting: Provides low‑impedance, mechanically secure connections suited to high‑current service and repeated maintenance cycles.
• Large capacitance in a single component: 10,000 µF reduces the need for parallel arrays when design space and board layout favor a single high‑value capacitor.
• RoHS compliance: Meets RoHS directive requirements for restricted substances.
