LNK2G822MSEJBB

The LNK2G822MSEJBB from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNK series designed for general-purpose power applications. This polarized radial can delivers 8.2 mF (8200 µF) capacitance at a 400 V rated voltage, in a compact φ90 × 120 mm form factor with screw terminals for secure mechanical and electrical connections.

Engineered for demanding power systems, the device offers a 5000‑hour load life at 85°C, wide operating temperature range and high ripple current capability, making it suited to industrial power supplies, energy storage and other high‑voltage DC applications requiring robust bulk capacitance.

Key Features

• High capacitance and voltage: 8.2 mF (8200 µF) rated at 400 V for bulk energy storage and filtering in high‑voltage DC systems.
• Screw terminal mounting: Radial can with screw terminals provides secure, low‑resistance connections and straightforward installation for high‑current bus connections.
• Load life: 5000 hours at 85°C under rated ripple current, specified by the LNK series endurance test conditions.
• Wide operating temperature: −25°C to +85°C, suitable for many industrial ambient environments.
• Ripple current capability: 22.9 A at 120 Hz and 32.06 A at 10 kHz, enabling effective smoothing of high ripple loads (specified ripple current values).
• Electrical characteristics: ±20% capacitance tolerance (at 120 Hz, 20°C) and tan δ = 0.2 as provided for this part.
• Reliability and safety checks: Leakage current limit after 5 minutes ≤ 3√(C·V) μA or 5 mA (whichever is smaller) at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• RoHS compliant: Meets the RoHS directive requirements stated for the product.

Typical Applications

• Industrial power supplies: Bulk smoothing and energy storage for high‑voltage DC rails and power conversion stages where high capacitance at 400 V is required.
• Motor drives and inverters: DC bus decoupling and ripple attenuation in systems that demand high ripple current handling and durable screw‑terminal connections.
• Energy storage buffers: Short‑term energy buffering and filtering in UPS or backup power modules operating within the specified temperature and life conditions.

Unique Advantages

• High energy density for high voltage designs: 8.2 mF at 400 V provides substantial bulk capacitance in a compact φ90×120 mm can for space‑constrained assemblies.
• Robust mechanical and electrical connection: Screw terminals simplify integration into busbar and high‑current layouts, improving assembly reliability.
• Specified ripple performance: Rated ripple current values at both low and high frequencies (120 Hz and 10 kHz) support accurate thermal and lifetime planning.
• Proven endurance specification: 5000 hours at 85°C under rated ripple and DC bias, with defined capacitance, tan δ and leakage requirements for predictable long‑term behavior.
• Clear verification criteria: Datasheet‑specified leakage, insulation resistance and voltage proof limits enable straightforward electrical acceptance testing.
• Regulatory compliance: RoHS compliance supports use in assemblies that require restricted‑substance adherence.
