LNK2G822MSEHBB

The LNK2G822MSEHBB is an aluminum electrolytic capacitor in a screw-terminal, radial can package from Nichicon’s LNK series. It delivers 8.2 mF (8200 µF) capacitance at a 400 V rating with polarized construction and is specified for general-purpose applications.

Designed for higher-voltage power applications, the capacitor combines high bulk capacitance, defined ripple-current capability, and a 5000-hour load-life rating at 85°C to support long-term performance in demanding DC bus and filtering roles.

Key Features

• Capacitance & Rated Voltage — 8.2 mF (8200 µF) nominal capacitance rated at 400 V for substantial energy storage on high-voltage DC rails.
• Screw Terminal Mounting — Radial can with screw terminals provides secure mechanical fastening and robust high-current connections.
• Load-Life Endurance — Specified for 5000 hours of operation at 85°C with rated ripple current applied, enabling predictable lifetime planning.
• Ripple Current Ratings — 22.7 A at 120 Hz and 31.78 A at 10 kHz, supporting effective smoothing across low and high-frequency ripple conditions.
• Operating Temperature Range — Usable from −25 °C to +85 °C for general-purpose environments.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is not more than 3√CV (µA) or 5 mA (whichever is smaller) at 20 °C, per datasheet guidance.
• Tolerance & Polarization — Capacitance tolerance ±20% at 120 Hz, 20 °C; polarized construction.
• Physical Size & Package — Radial screw-terminal can; dimensions L: 15.5 × D: 7.62 cm consistent with the LNK smaller-sized series form factor.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering: Bulk smoothing of high-voltage DC rails in general-purpose power supplies using the 400 V rating and high capacitance.
• DC bus energy storage: Bulk energy and ripple suppression for converters and DC-link circuits where sustained ripple handling and high voltage are required.
• Industrial power electronics: General-purpose industrial equipment requiring high-voltage electrolytic bulk capacitance and robust screw-terminal connections.

Unique Advantages

• High-voltage bulk capacitance: 8.2 mF at 400 V provides substantial stored energy for DC bus and smoothing duties.
• Defined ripple capability: Specified ripple currents at 120 Hz and 10 kHz enable designers to quantify thermal and lifetime effects under real operating conditions.
• Reliable long-term performance: 5000-hour load-life at 85 °C with applied ripple current offers a measurable endurance characteristic for lifetime estimation.
• Secure, serviceable termination: Screw-terminal radial can simplifies installation, high-current connections, and replacement when required.
• Measurable leakage behavior: Leakage current limits (3√CV µA or 5 mA after 5 minutes at 20 °C) support predictable startup and bias behavior in designs.
• RoHS compliance: Meets current RoHS requirements for lead-free assemblies.
