LNK2W222MSEGBB

The LNK2W222MSEGBB from Nichicon is a screw‑terminal, smaller‑sized aluminum electrolytic capacitor rated at 2.2 mF (2200 µF) and 450 V. It is designed for general‑purpose applications that require a polarized, high‑voltage electrolytic capacitor with elevated ripple handling and extended load life.

Key value propositions include a high ripple current capability across low and high frequencies, a rated operating range from −25 °C to 85 °C, and a demonstrated load life of 5000 hours at 85 °C under ripple current stress.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 450 V and a capacitance tolerance of −20% to +20% at 120 Hz, 20 °C.
• Screw Terminal Package — Radial can with screw terminals for secure, high‑current connections and straightforward mounting in rack and chassis assemblies.
• High Ripple Current Handling — Rated ripple current of 9 A at 120 Hz and 12.6 A at 10 kHz to support applications with significant AC ripple components.
• Temperature & Lifetime — Operates from −25 °C to +85 °C with a specified load life of 5000 hours at 85 °C when subjected to rated ripple current and DC bias.
• Endurance & Reliability — After endurance testing (5000 h at 85 °C with DC bias plus rated ripple) the capacitor meets capacitance change and dissipation factor limits specified in the series datasheet.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) μA or 5 mA, whichever is smaller (measured at 20 °C) as defined in the series datasheet.
• Physical Footprint — Smaller-sized design with dimensions L: 9 × D: 6.35 cm and a maximum seated height of 3.543 inch, useful where space and secure terminations are needed.
• RoHS Compliant — Meets RoHS directive requirements for restricted materials.
• Polarized Component — Designed as a polarized electrolytic capacitor for DC applications requiring polarity-specific energy storage.

Typical Applications

• High‑voltage DC systems — Applications that require a 450 V, 2.2 mF polarized capacitor with screw terminals for reliable DC filtering and energy buffering.
• Industrial power equipment — Systems benefiting from high ripple current capability and a robust load life at elevated temperature.
• Chassis‑mounted assemblies — Installations where screw‑terminal connections and a compact, smaller‑sized can simplify mechanical and electrical integration.

Unique Advantages

• High ripple tolerance: 9 A at 120 Hz and 12.6 A at 10 kHz provides margin for applications with substantial AC components.
• Long operational life at elevated temperature: 5000 hours at 85 °C under rated ripple current supports sustained performance in demanding environments.
• Secure, serviceable connections: Screw terminals enable robust electrical contact and ease of field replacement or service.
• Clear performance limits: Leakage current and endurance limits are specified in the datasheet for predictable behavior and design validation.
• Regulatory compliance: RoHS compliance reduces material risk for regulated markets.
