LNT2W221MSEC

The LNT2W221MSEC is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications that require high voltage handling and durable long‑life performance. It is a radial can, screw‑terminal package with a 450V rated voltage and 220µF capacitance, offering a combination of high ripple capability and extended life at elevated temperatures.

Engineered for applications demanding sustained ripple current and stable operation up to +105°C, this part provides a practical solution for power filtering, energy storage and DC bus support in systems that use screw‑terminal mounting.

Key Features

• Rated Capacitance and Voltage — 220 µF capacitance at a 450 V rated voltage with ±20% tolerance, suitable for high‑voltage DC applications.
• High Ripple Current Handling — 1.8 A at 120 Hz (low frequency) and 2.52 A at 100 kHz (high frequency) to support smoothing and ripple absorption in power circuits.
• Long Life and Temperature Rating — 5,000 hours rated life at 105°C, with an operating temperature range of −25°C to +105°C for stable high‑temperature performance.
• Low Loss and Leakage — tan δ specified at 0.2 and a leakage current of 940 µA, providing predictable electrical characteristics after installation.
• Robust Screw‑Terminal Package — radial can with screw terminals (φ35 × 80L, overall dimensions L: 8 × D: 3.5 cm) for secure mechanical and electrical connections.
• Polarized Electrolytic — designed as a polarized aluminum electrolytic capacitor for DC applications.
• RoHS Compliant and Production Ready — RoHS status compliant, shipped in cardboard packing, and available in mass production quantities.

Typical Applications

• General Purpose Power Systems — Suitable where a high‑voltage, high‑capacitance, screw‑terminal electrolytic capacitor is required for DC link or bulk storage.
• Industrial Power Supplies — Used to manage ripple and transient energy in industrial converters and power modules that operate near +105°C.
• Power Filtering and Smoothing — Employed in circuits requiring sustained ripple handling at both low and high frequencies to stabilize DC rails.

Unique Advantages

• High Voltage Capability — 450 V rating enables use in higher‑voltage DC systems without stacking multiple capacitors.
• Dual‑Frequency Ripple Performance — Specified ripple current at 120 Hz and 100 kHz supports performance across both mains‑frequency and switching‑frequency environments.
• Extended High‑Temperature Life — 5,000 hour life at 105°C offers predictable longevity for designs exposed to elevated operating temperatures.
• Screw‑Terminal Reliability — Robust screw terminal mounting provides secure electrical connection and simplifies integration into enclosures and busbar systems.
• Controlled Electrical Losses — tan δ of 0.2 and defined leakage current (940 µA) give clear expectations for power loss and standby behavior.
• Production and Environmental Readiness — RoHS compliance, cardboard packing, and mass production availability streamline procurement and deployment.
