LNK2W822MSEHBB

The LNK2W822MSEHBB is an aluminum electrolytic capacitor in a screw-terminal, radial-can package providing 8.2 mF (8200 µF) capacitance at a 450 V rating. Designed for general-purpose, high-voltage applications, it delivers bulk energy storage and smoothing in systems that require sustained ripple handling and long operational life.

This part features a φ76.2 × 190 mm (diameter × length) can with screw terminals, RoHS compliance, and a rated operating temperature range of −25°C to +85°C with a 5000-hour load life at 85°C under rated ripple conditions.

Key Features

• Capacitance and Voltage — 8.2 mF (8200 µF) rated at 450 V for high-voltage DC energy storage and smoothing requirements.
• Screw-terminal radial can package — Radial, can-style housing with screw terminals for secure, high-current connections and straightforward mechanical mounting.
• Rated lifetime — Load life specification of 5000 hours at 85°C when DC bias plus rated ripple current is applied (peak voltage not to exceed rated voltage).
• Ripple current capability — Specified ripple current 19.1 A at 120 Hz and 26.74 A at 10 kHz, enabling effective handling of low- and high-frequency ripple components.
• Wide operating temperature range — Specified for −25°C to +85°C to support a range of ambient conditions.
• Leakage current specification — After 5 minutes’ application of rated voltage at 20°C, leakage current is not more than 3√CV (µA) or 5 mA, whichever is smaller (C: µF, V: V).
• Insulation and dielectric proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; no abnormality under AC 2500 V for 1 minute between terminal and bracket.
• Polarized design with tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (±20%).
• RoHS compliant — Manufactured in compliance with RoHS directives as specified in the datasheet.

Typical Applications

• High-voltage power supplies — Bulk energy storage and smoothing where 450 V rating and 8200 µF capacitance are required for DC link stability.
• Industrial power conversion — Filtering and ripple management in converters and inverters that operate at elevated DC voltages and require sustained ripple handling.
• Energy storage and smoothing — Local DC energy buffering and transient suppression in systems that demand long life at elevated operating temperature (5000 h at 85°C).

Unique Advantages

• High-voltage, high-capacitance solution: 8200 µF at 450 V provides significant bulk energy storage in a single component, reducing component count for DC link designs.
• Designed for sustained ripple: Explicit ripple current ratings (19.1 A at 120 Hz; 26.74 A at 10 kHz) support both low- and high-frequency ripple environments.
• Proven endurance under heat: 5000-hour load life at 85°C under rated ripple and DC bias gives a defined reliability baseline for thermal design and lifetime planning.
• Robust electrical isolation: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V dielectric proof between terminal and bracket help ensure stable, safe operation in high-voltage assemblies.
• Screw-terminal convenience: Heavy-duty terminal fixation simplifies high-current connections and maintenance in field-serviceable equipment.
• RoHS compliance: Meets regulatory requirements for lead-free assembly and environmental directives where applicable.
