4221-1 Description

Short technical summary and product information.

The API Delevan Inc. 4221-1 is a single-line surface mount ferrite bead designed for EMI suppression in high-current applications. It offers a nominal impedance of 47 Ω at 100 MHz, making it suitable for filtering noise on power and signal lines.

 

The component is rated for a maximum continuous current of 5 A and features a low typical DC resistance of 0.8 mΩ, minimizing power loss and heat generation. It operates over a wide temperature range of -55°C to 125°C, ensuring reliability in harsh environments.

 

Housed in a compact 2-SMD J-Lead package (5.00 mm x 3.05 mm x 3.25 mm), the 4221-1 is compatible with standard surface mount assembly processes. Its single-line design focuses on filtering a single conductor.
