LNY2G822MSEGBB

The LNY2G822MSEGBB is an aluminum electrolytic capacitor in a screw-terminal, radial-can package offering 8200 µF nominal capacitance at a 400 V rating. It is part of Nichicon's LNY series and is designed for general-purpose, high-voltage applications where compact energy storage and secure terminal connections are required.

Key value propositions include high capacitance at a 400 V rating, robust ripple-current capability, a rated operating range of −40 °C to +85 °C, and a specified load life of 2000 hours at 85 °C with applied ripple current. The device is RoHS compliant.

Key Features

• High Capacitance: 8.2 mF (8200 µF) nominal capacitance for substantial bulk energy storage and smoothing.
• 400 V Rated Voltage: Rated for 400 V operation to support high-voltage power designs within the LNY series voltage range.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-resistance electrical connections for robust assembly and maintenance.
• Load Life — 2000 hours at 85 °C: Endurance specification with rated ripple current applied for 2000 hours at 85 °C, with performance restored to 20 °C per datasheet conditions.
• High Ripple Current Capability: Rated ripple current of 21.2 A at 120 Hz and 29.68 A at 10 kHz, enabling effective handling of AC ripple in power conversion circuits.
• Wide Temperature Range: Specified operating range from −40 °C to +85 °C for general-purpose environmental conditions.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller (at 20 °C), as defined in the series datasheet.
• Insulation and Voltage Proof: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; no abnormality at AC 2500 V applied for 1 minute between terminal and bracket (series-level data).
• Package & Marking: Radial can with screw terminals; dimensions listed as L: 21 × D: 6.35 cm and sleeve marked with white lettering on a black background.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power supplies: Bulk capacitance and smoothing in equipment that requires a 400 V rated electrolytic capacitor.
• Equipment downsizing and compact power units: Suited for designs targeting reduced enclosure size while retaining high bulk capacitance.
• Industrial power electronics: Secure screw-terminal connections and high ripple-current capability make it suitable for general-purpose industrial converters and assemblies.

Unique Advantages

• Significant energy storage at high voltage: 8.2 mF at 400 V provides substantial bulk capacitance for smoothing and transient support without increasing system voltage stress.
• Designed for ripple-heavy environments: Specified ripple currents (21.2 A at 120 Hz, 29.68 A at 10 kHz) enable reliable operation under AC ripple loading conditions.
• Secure, service-friendly connections: Screw terminal mounting simplifies assembly, maintenance, and high-current terminations.
• Endurance-backed performance: Load-life rating of 2000 hours at 85 °C with applied ripple current gives a measurable durability metric for design verification.
• Regulatory compliance: RoHS conformity supports designs targeting restricted-substance requirements.
• Measurable insulation and dielectric robustness: Insulation resistance and voltage-withstand criteria in the datasheet provide quantifiable safety and isolation characteristics.
