  1. The Price Of Reliability: Considerations For Buyers 5/31/2019

    By making a small component change, one could extend an implantable medical device's reliability and lifespan by preventing battery-related complications. This paper explores the cost of device failures and discusses how proper testing and supplier considerations can help capacitor sourcing.

  2. When Reliability Is Paramount: Selecting Capacitors For Life-Critical Applications 4/10/2019

    This white paper explores regulation, testing procedures, and supplier considerations to assist in choosing the best components for each medical application. 

  3. Filter Shape Factor And Selectivity 3/8/2019

    This article discusses how a real-world filter’s deviation from ideal behavior needs to be quantified and that shape factor and selectivity are tools to use in this process. It touches on how both resonator Q and the filter order (number of resonators in a design) can influence a filter's behavior in the transition band. 

  4. Medical Imaging Quality Starts By Selecting The Right Components

    MRI machines produce cross-sectional images using a strong magnetic field and computer-generated radio waves. Thus, the quality of the MRI depends on field uniformity and the radio components inside.
