LNK2V122MSEF

The LNK2V122MSEF is a screw‑terminal, radial-can aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 1200 µF at 350 V with polar construction and is optimized for systems requiring high ripple handling and long operational life in industrial temperature ranges.

This part combines a compact φ51 × 70L package with robust electrical characteristics — including rated ripple current handling at low and high frequencies, a 5000‑hour endurance at 85°C, and RoHS compliance — making it suitable for power supplies, converters, and other high‑voltage DC systems.

Key Features

• Capacitance and Voltage: 1.2 mF (1200 µF) rated at 350 V DC for energy storage and bulk filtering in high‑voltage circuits.
• Screw‑Terminal Mounting: Radial, can package with screw terminals for secure mechanical and electrical connections in high‑current applications.
• High Ripple Capability: Rated ripple current of 5.5 A at 120 Hz and 7.7 A at 10 kHz to support both low‑ and high‑frequency ripple environments.
• Endurance: 5000 hours load life at 85°C under rated ripple conditions, delivering long service life in elevated‑temperature installations.
• Temperature Range: Operates from −25°C to +85°C to cover a wide range of industrial ambient conditions.
• Leakage and Loss: Specified leakage current of 1940 µA and tangent of loss angle (tan δ) of 0.2 for predictable DC behavior and dissipation.
• Insulation and Voltage Proof: Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket.
• Package and Marking: φ51 × 70L radial can with screw terminals, printed white on black sleeve; cardboard packing for mass production handling.
• Regulatory: RoHS compliant.

Typical Applications

• Power Supplies: Bulk energy storage and output filtering in high‑voltage DC power supplies where 350 V rating and high ripple tolerance are required.
• DC‑DC Converters and Inverters: Input and hold‑up capacitors for converters handling both low‑ and high‑frequency ripple currents.
• Industrial Electronics: Filtering and smoothing in industrial control systems and power modules operating within −25°C to +85°C.

Unique Advantages

• High Ripple Handling: Clear ripple ratings at 120 Hz (5.5 A) and 10 kHz (7.7 A) support diverse switching and mains‑frequency workloads.
• Long Operational Life: 5000‑hour endurance at 85°C under rated conditions provides predictable life‑cycle planning for deployed systems.
• Robust Electrical Safety Margins: High insulation resistance and AC voltage proofing between terminal and bracket enhance reliability in high‑voltage assemblies.
• Secure Mechanical Termination: Screw‑terminal construction enables firm, low‑impedance connections for high‑current paths and simplifies field serviceability.
• RoHS Compliance: Meets RoHS requirements for easier regulatory alignment in production and distribution.
• Flame‑Retardant Option Available: A flame‑retardant electrolyte version is offered within the series for applications that require it.

Why Choose LNK2V122MSEF?

LNK2V122MSEF is positioned for designs that need a durable, high‑voltage electrolytic capacitor with demonstrable ripple performance and long life at elevated temperatures. Its screw‑terminal radial can package and specified electrical protections make it suitable for power supplies, converter systems, and industrial electronics where secure connections and predictable endurance are important.

Engineers and procurement teams benefit from explicit electrical specifications — capacitance, voltage, ripple current across frequencies, leakage current, and defined endurance — enabling straightforward selection, lifetime estimation, and integration into assemblies that require RoHS compliance and reliable high‑voltage bulk capacitance.
