LNC2W272MSEHBB

The LNC2W272MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series, designed for high-voltage power conversion and inverter applications. This smaller-sized, high-ripple-current can delivers 2700 µF at 450 V with a compact radial screw-terminal package suited to industrial power supplies and regenerative inverter circuitry.

Key value propositions include high ripple-current handling across low and high frequencies, a 5000-hour endurance rating at 85°C, and a broad operating range from −40°C to 85°C for robust performance in demanding power systems.

Key Features

• Electrical Capacity — 2.7 mF (2700 µF) rated capacitance at 450 V with ±20% tolerance for energy storage in high-voltage power systems.
• High Ripple Current — Rated ripple current of 13.7 A at 120 Hz and 19.18 A at 100 kHz to support both low-frequency smoothing and high-frequency charge/discharge demands.
• Endurance and Temperature — Load-life endurance of 5000 hours at 85°C and an operating temperature range of −40°C to 85°C for sustained reliability under elevated temperature and cyclic loading.
• Leakage and Dissipation — Specified leakage current of 3300 µA and tangent of loss angle (tan δ) of 0.2, enabling predictable loss and self-discharge characteristics.
• Mechanical & Mounting — Radial can with screw terminals (screw terminal type) for secure, low-resistance connections in power assemblies; physical dimension approximately φ76.2 × 75 mm (L: 7.5 × D: 7.62 cm).
• Compliance & Packaging — RoHS compliant; supplied in cardboard packing and available for mass production quantities.

Typical Applications

• Industrial Power Supplies — Energy smoothing and buffering in high-voltage power supplies used for inverter and drive electronics.
• AC Servo and Motor Drives — Handling regenerative voltage and high-frequency charge/discharge cycles in servo and motor-control inverters.
• High-Frequency Inverters — Supports high-speed switching environments with elevated ripple current at both low and high frequencies.

Unique Advantages

• High ripple-current capability: 13.7 A (120 Hz) and 19.18 A (100 kHz) ratings reduce heating and extend life under heavy AC ripple loading.
• Long operational life at elevated temperature: 5000-hour endurance at 85°C provides predictable lifetime metrics for design planning and maintenance schedules.
• Compact, screw-terminal radial can: Smaller-sized construction with screw terminals enables secure mounting and reliable current-carrying connections in constrained power assemblies.
• Wide operating temperature: −40°C to 85°C operation supports use across varied industrial environments and seasonal extremes.
• Clear electrical characteristics: Defined leakage (3300 µA) and loss tangent (tan δ 0.2) permit accurate thermal and efficiency calculations in system design.
