LNK2W272MSEG

The LNK2W272MSEG is a Nichicon LNK series aluminum electrolytic capacitor in a screw-terminal radial can package, offering 2.7 mF (2700 µF) capacitance at a 450 V rating. Designed as a smaller-sized, screw-terminal option within the LNK family, it provides high ripple current handling and long service life for general-purpose high-voltage applications.

Key performance characteristics include rated operation from −25 °C to +85 °C, a rated life of 5000 hours at 85 °C under rated ripple current, and RoHS compliance—making it suitable for assemblies that require robust high-voltage bulk capacitance and reliable ripple endurance.

Key Features

• High Voltage Rating (450 V) — Rated for 450 V operation, enabling use in higher-voltage circuits within the LNK series voltage range.
• Large Capacitance (2.7 mF / 2700 µF) — Provides substantial bulk capacitance for energy storage and decoupling in high-voltage designs with a ±20% tolerance.
• High Ripple Current Capacity — Rated ripple currents of 10.5 A at 120 Hz and 14.7 A at 10 kHz support applications with significant AC or switching ripple stress.
• Screw Terminal Radial Can Package — Screw terminal mounting simplifies secure mechanical and electrical connections in power assemblies.
• Wide Operating Temperature Range — Specified for −25 °C to +85 °C operation to handle a broad set of environmental conditions.
• Long Rated Life — Endurance specified as 5000 hours at 85 °C under rated ripple current, with capacitance change and leakage limits defined by the LNK series specifications.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.
• Compact Footprint — Described as a smaller-sized member of the LNK series with radial can, screw-terminal construction and defined package dimensions for space-conscious designs.

Typical Applications

• General-purpose high-voltage power circuits — Provides bulk capacitance and ripple handling where 450 V ratings and large capacitance values are required.
• High-voltage energy storage in assemblies — Suitable for applications that need sustained capacitance and endurance under ripple load conditions.
• Power module and board-level installations — Screw terminal mounting and a radial can package enable secure integration in power assemblies and modules.

Unique Advantages

• High voltage and high capacitance combined — 450 V rating with 2700 µF capacity addresses designs that demand both high energy storage and high voltage tolerance.
• Engineered for ripple endurance — Specified ripple current ratings at both low and high frequencies (10.5 A at 120 Hz, 14.7 A at 10 kHz) reduce thermal stress and extend service life under AC loading.
• Durability at elevated temperature — 5000-hour rated life at 85 °C under rated ripple conditions supports longer maintenance intervals and predictable aging.
• Secure screw-terminal connectivity — Facilitates reliable electrical and mechanical connections in power assemblies, simplifying installation and replacement.
• RoHS compliant — Meets environmental requirements for restricted substances, simplifying regulatory compliance for supplied assemblies.
