LNK2G122MSEFBN

The LNK2G122MSEFBN is a screw‑terminal aluminum electrolytic capacitor providing 1.2 mF (1200 µF) capacitance at a 400 V rated voltage in a radial can with screw terminals. It is designed for general‑purpose power applications where secure bolted connections, high voltage capability and long endurance are required.

Key benefits are its high working voltage and substantial ripple handling combined with a compact φ51 × 75 mm package, making it suitable for high‑voltage filtering and energy smoothing in industrial power systems and other general‑purpose power electronics.

Key Features

• Capacitance & Rated Voltage: 1.2 mF (1200 µF) nominal capacitance with a 400 V rated voltage for high‑voltage DC circuits.
• Tolerance & Loss Factor: ±20% capacitance tolerance at 120 Hz and tanδ (DF) = 0.2 for predictable impedance and loss behavior.
• Endurance & Temperature Range: 5000 hours life when subjected to rated ripple current at 85°C; operating temperature range −25°C to +85°C.
• Ripple Current Performance: Rated ripple current 5.8 A at 120 Hz and 8.12 A at 10 kHz, supporting both low‑ and high‑frequency ripple environments.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is specified as not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C), per datasheet guidance.
• Robust Mechanical & Mounting: Screw terminal, radial can package for secure electrical connection and ease of installation; nominal size φ51 × 75 mm (D × L).
• Series Range (LNK): Series covers rated voltages from 350 to 500 V and capacitances from 1000 to 18000 µF, offering scalable options within the same family.
• Regulatory Compliance: RoHS‑compliant construction.

Typical Applications

• General‑purpose power supplies: Bulk filtering and energy storage in high‑voltage DC supply rails where 400 V rating and high capacitance are required.
• Industrial power electronics: DC link smoothing and ripple suppression in industrial converters and inverters that demand robust screw‑terminal connections.
• High‑frequency ripple environments: Applications with mixed low and high frequency ripple, leveraging the specified ripple current at 120 Hz and 10 kHz.

Unique Advantages

• High‑voltage capability: 400 V rating provides headroom for many high‑voltage DC circuits without series stacking.
• Long endurance at elevated temperature: 5000 hours rated life at 85°C under rated ripple current improves system reliability and mean time between service intervals.
• Secure screw‑terminal mounting: Screw terminals provide a durable electrical connection for installations that require mechanical robustness and easy servicing.
• Broad ripple performance: Specified ripple current values at both 120 Hz and 10 kHz accommodate a range of switching and line‑frequency distortion conditions.
• Clear leakage specification: Leakage current limits defined by 3√(C·V) µA or 5 mA ensure predictable in‑circuit behavior after voltage application.
• RoHS compliance: Meets RoHS directive requirements for environmental compliance.
