LNK2W272MSEH

The LNK2W272MSEH is an aluminum electrolytic, screw-terminal capacitor engineered for general-purpose power applications. It provides 2700 µF capacitance at a 450 V rating in a radial can with screw terminals and is specified for operation from −25 °C to +85 °C.

Designed for high ripple-current duty and extended load life, this part targets power conditioning and energy-storage roles where high voltage, robust termination, and long-term reliability are required.

Key Features

• Rated Capacitance and Voltage — 2700 µF at 450 V provides substantial bulk capacitance for high-voltage DC systems.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance connections and easy mechanical mounting.
• High Ripple Current Capability — Specified ripple current of 11 A at 120 Hz and 15.4 A at 10 kHz to support demanding AC ripple environments.
• Temperature and Lifetime — Operating range −25 °C to +85 °C with a rated load life of 5000 hours at 85 °C under specified ripple current conditions.
• Leakage and Insulation — Leakage current after 5 minutes is limited to 3√CV (µA) or 5 mA, whichever is smaller (at 20 °C); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• Endurance and Voltage Proof — Endurance limits maintain capacitance within ±20% after life testing; voltage proof tested at AC 2500 V for 1 minute between terminal and bracket.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
• Physical Size — Compact radial can dimensions: L: 9.0 cm × D: 7.62 cm for space-conscious layouts.

Typical Applications

• Power supply filtering: Bulk smoothing and ripple reduction in high-voltage DC power supplies where 450 V rating and high ripple current are required.
• Power conversion and conditioning: Energy buffering in converters and inverters that demand high-voltage bulk capacitance and robust terminal connections.
• Industrial equipment: General-purpose energy storage and decoupling in industrial control and power-distribution systems operating within −25 °C to +85 °C.

Unique Advantages

• High-voltage bulk storage: 450 V rating combined with 2700 µF capacitance provides sizable energy reserve for high-voltage designs.
• Robust electrical termination: Screw terminals deliver reliable, low-resistance connections suitable for high-current ripple environments.
• Engineered for ripple endurance: Specified ripple current ratings at 120 Hz and 10 kHz enable use in applications with significant AC components on DC rails.
• Proven longevity: 5000-hour load life at 85 °C under rated ripple current supports long-term deployment in continuous-duty systems.
• Safety-related insulation characteristics: High insulation resistance and AC 2500 V voltage-proof testing between terminal and bracket enhance electrical reliability in high-voltage assemblies.
• Regulatory compliance: RoHS compliance simplifies environmental qualification for restricted-substance requirements.
