LNK2G183MSEJBB

The LNK2G183MSEJBB is an aluminum electrolytic capacitor in Nichicon’s LNK series, engineered as a screw‑terminal, smaller‑sized radial can for general‑purpose power applications. It provides high capacitance at elevated DC voltage (18,000 µF at 400 V) with robust ripple handling and long load life for demanding energy‑storage and filtering tasks.

Key attributes include high rated ripple current, a broad operating temperature range, and RoHS compliance—making it suitable for equipment designs that require sustained performance under continuous ripple and thermal stress.

Key Features

• High Capacitance at High Voltage — Rated capacitance 18,000 µF at 400 V, ideal where substantial energy storage and DC voltage handling are required.
• Screw Terminal Mounting — Radial can package with screw terminals for secure electrical connections and straightforward chassis or bracket mounting.
• High Ripple Current Capability — Rated ripple current of 41.2 A at 120 Hz and 57.68 A at 10 kHz, with frequency coefficients provided for other operating frequencies.
• Operating Temperature and Lifetime — Specified for −25 °C to +85 °C operation with a load life of 5000 hours at 85 °C under rated ripple current.
• Leakage Current Specification — After 5 minutes at rated voltage and 20 °C, leakage is not more than 3√CV (µA) or 5 mA, whichever is smaller.
• Capacitance Tolerance — ±20% at 120 Hz, 20 °C.
• RoHS Compliant — Meets RoHS directive requirements as stated in the product datasheet.
• Compact LNK Series Form Factor — Smaller‑sized LNK series design with radial can and screw terminals; size dimension listed as L: 23.5 × D: 9 cm.

Typical Applications

• General‑purpose power equipment — Energy storage and bulk filtering in general‑purpose DC power circuits that require high capacitance at 400 V.
• High‑ripple power stages — Applications that demand sustained ripple handling benefit from the capacitor’s rated ripple currents at both low and high frequencies.
• Chassis or bracket mounted systems — Screw‑terminal radial can package and available mounting bracket dimensions facilitate secure installation in cabinet or frame designs.

Unique Advantages

• Substantial energy storage at high voltage: 18,000 µF at 400 V supports longer hold‑up and smoothing intervals in DC systems.
• Designed for continuous ripple: High rated ripple currents (41.2 A @120 Hz, 57.68 A @10 kHz) and frequency coefficients help maintain performance across operating conditions.
• Extended endurance under load: 5000‑hour load life at 85 °C under rated ripple current provides predictable long‑term behavior for sustained use.
• Robust electrical controls: Specified leakage current limits (3√CV µA or 5 mA max after 5 minutes at 20 °C) and insulation/voltage proof requirements support reliable operation.
• Installation flexibility: Screw terminals and radial can package simplify secure mechanical and electrical mounting in bracketed systems.
• Regulatory compliance: RoHS compliance aligns the component with common environmental directives.
