Key Parameters for Selecting RF Inductors

January 23, 2008 4:42 am | Product Releases | Comments

By Chris Hare, Coilcraft What factors do I need to consider? RF inductor selection involves seven key parameters: mounting (surface mount or through-hole), inductance value, current rating, DC resistance (DCR), self-resonant frequency (SRF), Q factor, and temperature rating. While small size is typically desired, the laws of physics limit how small an inductor can be for a given application....

Integrated EMI Filters and the Need for More Bandwidth

December 12, 2007 5:36 am | Product Releases | Comments

In previous generations of cell phones, when the design called for more data to be moved around, the solution was to add more data lines. Only a handful of data lines were sufficient at first, since there was only basic numeric data to be displayed and data rates were rather low. We all remember the old analog flip phones with their LED displays, you pushed the keypad and a digit appeared....
