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...
