LNK2V222MSEFBB

The LNK2V222MSEFBB from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNK series designed for general-purpose high-voltage applications. It provides 2.2 mF capacitance at a 350 V rating in a radial can with screw terminals for secure, serviceable connections.

Engineered for sustained ripple-loading, this part is specified for 5000 hours of operation at 85°C under rated ripple current and is RoHS compliant, making it suitable where long life and environmental compliance are required.

Key Features

• Electrical Performance — 2.2 mF rated capacitance with a voltage rating of 350 V and capacitance tolerance of −20% to +20%.
• High Ripple Current Capability — Rated ripple current: 8.2 A at 120 Hz and 11.48 A at 10 kHz, with frequency coefficients provided in the series datasheet for other frequencies.
• Long Load Life — Rated for 5000 hours at 85°C when subjected to DC bias plus rated ripple current, with post-test limits defined for capacitance change, tan δ and leakage current.
• Temperature and Stability — Operational range of −25°C to +85°C and impedance stability specification (Z at −25°C / Z at +20°C ≤ 8 for 350–500 V range).
• Robust Insulation and Voltage Withstand — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Screw Terminal Package — Radial can with screw terminals for reliable bolted connections; physical size L: 9.5 cm × D: 5.1 cm and a maximum seated height of 3.74 inch for mechanical planning.
• Leakage and Loss Characteristics — Leakage current limit defined as not more than 3√CV (μA) or 5 mA (whichever is smaller) after 5 minutes at rated voltage; tan δ reference and measurement conditions provided in the datasheet.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage DC power supplies — Bulk energy storage and smoothing where 350 V rating and high ripple capability are required.
• Industrial power electronics — DC bus filtering and ripple handling in systems requiring durable screw‑terminal connections.
• Backup and hold‑up circuits — Energy buffering for short-term hold‑up where long operational life at elevated temperature is important.

Unique Advantages

• 350 V rating for higher-voltage systems — Supports designs that require elevated DC voltage handling without multiple series capacitors.
• High specified ripple current — Explicit 120 Hz and 10 kHz ripple current ratings simplify thermal and lifetime planning for high‑ripple applications.
• Proven endurance at elevated temperature — 5000 hours at 85°C under rated ripple current provides a clear durability benchmark for design validation.
• Screw terminal reliability — Radial can with screw terminals enables secure, serviceable electrical connections suitable for industrial assemblies.
• Measurable leakage and insulation specs — Defined leakage current limits and insulation resistance/voltage‑proof data support safety and QA test plans.
• RoHS compliance — Aligns with environmental regulations for restricted substances.
