LNK2V103MSEH

The LNK2V103MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNK series, designed for general-purpose power applications. It provides high bulk capacitance (10 mF) at a 350 V rating in a radial can with screw terminals for secure mechanical and electrical connections.

Engineered for elevated-temperature operation, this part delivers long service life under ripple load and is suitable for applications that require large energy storage, DC smoothing, or bulk filtering within the specified temperature and endurance limits.

Key Features

• Capacitance & Voltage — 10000 µF (10 mF) nominal capacitance rated at 350 V with ±20% tolerance at 120 Hz, 20°C.
• Thermal & Endurance — Rated operating temperature range of −25°C to +85°C with a rated load life of 5000 hours at 85°C under specified ripple conditions.
• Leakage and Loss Characteristics — Specified leakage current of 5000 µA and tangent of loss angle (tan δ) of 0.2 (measurement conditions per product data).
• High Ripple Handling — Rated ripple current of 25.1 A at 120 Hz and 35.14 A at 10 kHz, suitable for demanding AC ripple environments within the rated conditions.
• Mounting & Package — Radial can with screw terminals for reliable bolted connections; physical size φ76.2 × 155 mm (D × L) and packaged in cardboard packing for shipment.
• Compliance — RoHS compliant and produced as part of Nichicon’s mass-production lineup.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing for high-voltage DC power supplies where 350 V rating and large capacitance are required.
• Industrial Power Electronics — DC-link and filtering duties in industrial converters and inverters that operate within the −25°C to +85°C temperature window.
• Energy Storage / Buffering — Temporary energy buffering and ride-through support where high capacitance and defined ripple capability are needed.

Unique Advantages

• Large Bulk Capacitance: 10 mF provides substantial energy storage for DC smoothing and transient suppression.
• High Voltage Capability: 350 V rating allows use in higher-voltage DC systems without series stacking.
• Durability at Elevated Temperature: 5000-hour rated life at 85°C supports long-term operation under ripple load.
• Screw-Terminal Security: Screw terminals enable robust, low-resistance connections for high-current ripple paths.
• Documented Ripple Performance: Rated ripple currents at 120 Hz and 10 kHz provide clear design points for thermal and lifetime budgeting.
• Regulatory Compliance: RoHS compliance simplifies integration into regulated product lines.
