MEP EP#261: Critical Path Components

Parker

• What can you do to help alleviate component shortages and lead times in your design
  
  
  • Last week we talked about automotive component shortages
  
  
  • Passive components
    
    
    • Most passives it is easy to find substitutes
    
    
    • Check your specifications
      
      
      • Components that have extraordinary specs for there package size
      
      
      
      
    
    
    
    
  
  
  • Active components
    
    
    • Diversify what you can
      
      
      • Discretes
      
      
      • Diodes
      
      
      • Mosfets
      
      
      
      
    
    
    • Integrated Components
      
      
      • Different packages or packaging
      
      
      
      
    
    
    
    
  
  
  • Connectors
    
    
    • Different plating options possible?
    
    
    • Other manufactures making similar or compatible parts

• Searching for components kind of sucks sometimes. Another Quick idea for making this easier
  
  
  • Anything that is a complement
    
    
    • Connectors
    
    
    • Transistors
      
      
      • Guessed BCP54 - BCP52
      
      
      
      
    
    
    
    
  
  
  
  


• PCB Crosstalk
  
  
  
  • Video by Robert Feranec with Eric Bogatin
  
  
  • What causes PCB crosstalk?
    
    
    • Capacitive coupling
    
    
    • Inductive coupling
    
    
    
    
  
  
  • Effects of pcb crosstalk
  
  
  • How do we mitigate pcb crosstalk?
  
  
  • One other form of “crosstalk” that really isn't crosstalk
    
    
    • Poor filtering and PSRR
    
    
    • “Feedforward” current
    
    
    • Not really something that shows up often...
