Coilcraft, Inc. 0402DF (1005) Series Wirewound Ferrite Beads 0402DF-221

Our 0402DF Series wirewound ferrite beads have higher performance than others in the market, including high impedance across a wide bandwidth - up to GHz band. Ferrite construction and heavy gage wire means high current handling for 0402 size. Extremely low DCR assures lowest insertion loss for high efficiency in mobile applications. These small beads eliminate noise in small power supplies and provide isolation of RF signals. They can withstand high temperatures and are AEC-Q200 Grade 1 (−40°C to +125°C) qualified.

• Superior performance to other surface mount ferrite beads in the market
• High impedance across a wide bandwidth – up to GHz band
• Ferrite construction and heavy gauge wire for high current handling
• Extremely low DCR for high current applications
• Eliminates high frequency noise in power supplies or RF signal isolation applications
• AEC-Q200 Grade 1 (−40°C to +125°C)

Our 0402DF Series of wirewound ferrite chip inductors have the industry's lowest DCR in an 0402 size – up to 30% lower than the closest competitor. This series was developed for cellular applications for use as either filter elements, as one-pole filters, or as RF chokes in the cellular bands. These are ideal for use in mobile and infrastructure equipment.

• The Industry’s lowest DCR in an 0402 package – up to 30% lower than the closest competitor
• Developed for use in cellular applications:
  As a filter element in bandstop and low pass filters
  As a one pole filter or RF choke in cellular bands
• Ideal for use in mobile and infrastructure equipment.
• Higher inductance values than other 0402 inductors – up to 3300 nH
• Ferrite construction for high current handling
• Can also be used for ground-to-ground isolation
• AEC-Q200 Grade 1 (−40°C to +125°C)
