LNK2V222MSEFBN

The LNK2V222MSEFBN from Nichicon is a smaller-sized, screw-terminal aluminum electrolytic capacitor rated at 2200 µF (2.2 mF) and 350 V. It is designed for general-purpose power applications that require high ripple-current handling and robust long-term performance at elevated temperatures.

Built as part of Nichicon’s LNK series, this radial can with screw terminals combines high ripple capability, a wide operating temperature range, and RoHS compliance—making it suitable where reliable DC link and smoothing capacitance is required.

Key Features

• Capacitance & Voltage — 2200 µF (2.2 mF) nominal capacitance with a rated voltage of 350 V and ±20% tolerance at 120 Hz, 20°C.
• Screw-Terminal Package — Radial can with screw terminals for secure mechanical and electrical connections in high-current assemblies.
• High Ripple Current — Rated ripple current of 8.2 A at 120 Hz and 11.48 A at 10 kHz (frequency-dependent performance noted in datasheet).
• Temperature & Lifetime — Operating temperature range −25°C to +85°C with a specified load life of 5000 hours at 85°C under rated ripple conditions.
• Leakage & Insulation Characteristics — Leakage current specification: after 5 minutes at rated voltage, ≤ 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Frequency Performance — Frequency coefficient of rated ripple current is specified (example: coefficient 1.00 at 120 Hz and 1.40 at 10 kHz or more), enabling designers to account for ripple behavior across frequencies.
• Compliance — RoHS compliant per directive references provided in product documentation.
• Physical Dimensions — Smaller-sized footprint with package dimensions L: 9.5 cm × D: 5.1 cm and screw terminal mounting; nominal bolt size M5 per series drawing data.

Typical Applications

• General-purpose power electronics — Provides bulk capacitance and smoothing in high-voltage DC link and power supply circuits where 350 V rating and substantial ripple capability are required.
• Industrial power systems — Suitable for equipment that requires a robust screw-terminal capacitor with defined endurance at elevated temperatures.
• High-frequency ripple environments — Frequency-qualified ripple performance supports designs with significant high-frequency ripple currents up to 10 kHz and beyond.

Unique Advantages

• High ripple-current handling — Explicit rated ripple current values and frequency coefficients let engineers size capacitors for real operating conditions and heat dissipation.
• Screw-terminal reliability — Solid screw-terminal connections simplify installation and improve mechanical retention in applications with vibration or high current stress.
• Proven endurance at 85°C — 5000-hour load-life rating at 85°C under rated ripple current provides predictable long-term performance for sustained thermal environments.
• Measured leakage and insulation specs — Clear leakage-current limits and insulation-resistance requirements support predictable system behavior after voltage application and during verification tests.
• RoHS compliance — Conforms to RoHS directives noted in product documentation for regulatory alignment.
• Compact, smaller-sized form — The reduced package footprint helps conserve panel and chassis space while maintaining high-voltage and high-ripple capability.
