LNK2G183MSEJBN

The LNK2G183MSEJBN from Nichicon is an aluminum electrolytic capacitor in the LNK series, offered in a screw terminal, radial can package. Designed for general-purpose power applications, it provides high bulk capacitance and high ripple-current capability for DC-link smoothing and energy storage in power systems.

Key value propositions include a high rated voltage of 400 V, large capacitance (18,000 µF), extended load life of 5000 hours at 85 °C, and RoHS compliance for environmentally conscious designs.

Key Features

• Capacitance & Voltage — Rated capacitance of 18 mF (18,000 µF) with a rated voltage of 400 V and capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• High Ripple Current & Frequency Response — Specified ripple current performance includes 41.2 A at 120 Hz and 57.68 A at 10 kHz; frequency coefficients are provided for scaling ripple values across common frequencies (e.g., 0.80 at 50 Hz, 1.00 at 120 Hz, 1.40 at 10 kHz or more).
• Endurance & Reliability — Load life rated at 5000 hours when subjected to rated ripple current at 85 °C; endurance characteristics are defined in the datasheet for post-test verification.
• Operating Temperature Range — Specified operating range from −25 °C to +85 °C suitable for a variety of industrial and power environments.
• Package & Mounting — Screw terminal, radial can package for secure, high-current connections and straightforward installation in power assemblies.
• Leakage & Insulation — Leakage current specification: after 5 minutes at rated voltage, leakage is not more than 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance is specified at more than 100 MΩ at DC 500 V between terminal and bracket.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Smaller-sized Construction — LNK series smaller-sized screw terminal design offers high capacitance in a compact form factor relative to the series footprint.

Typical Applications

• Power Supplies — Bulk smoothing and DC-link energy storage in high-voltage power supplies, leveraging the 18,000 µF capacitance and 400 V rating to stabilize DC bus voltages.
• Industrial Power Conversion — DC bus filtering and ripple absorption in converters and inverters where high ripple-current capability and screw-terminal connections enable robust high-current wiring.
• Uninterruptible Power Supplies (UPS) & Backup Systems — Energy storage and smoothing for backup electronics, benefiting from the capacitor’s long load life (5000 hours at 85 °C) and wide operating temperature range.

Unique Advantages

• Large Bulk Capacitance: 18,000 µF provides substantial energy storage for DC-link and smoothing applications, reducing the need for multiple parallel components.
• High Voltage Rating: 400 V rating supports high-voltage power architectures without additional series stacking.
• High Ripple Handling: Measured ripple current ratings (41.2 A at 120 Hz, 57.68 A at 10 kHz) and frequency coefficients enable designers to size capacitors for real-world switching and line-frequency conditions.
• Robust Screw-Terminal Mounting: Screw terminals allow secure high-current terminations and simplify mechanical and electrical connections in power assemblies.
• Long Load Life: 5000-hour endurance at 85 °C under rated ripple current supports reliable operation in continuous-duty applications.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted substance adherence.
