28F0121-0SR Description

Short technical summary and product information.

The 28F0121-0SR is a single line ferrite bead designed for power line applications. It offers 48 Ω impedance at 100 MHz, with a maximum current rating of 10A and a low DC resistance of 0.75 mOhm. This low DCR makes it suitable for high current circuits where minimal power loss is required.

 

The component is housed in a compact 2-SMD J-Lead package measuring 3.05mm x 2.54mm x 3.05mm. It is surface mountable and operates over a temperature range of -40°C to 125°C. The J-Lead termination provides reliable solder joints.

 

This ferrite bead is commonly used for EMI suppression in DC power lines, such as those found in power supplies, converters, and automotive electronics. Its high current handling and low resistance make it ideal for filtering noise without significant voltage drop.
