Electrical Noise Suppression 
Electrical Noise can be a problem with low cost switching power converters.  The Goddard PS-5a has been very popular and I've never had any complaints about electrical noise from the PS-5a interfering with the aircraft radio. Below is a list of techniques used in the PS-5a to minimize electrical noise:

  • Internal ferrite shielding on both power and ground lines coming into the unit. 
  • Capacitive filtering on the power lines
  • RFI/EMI filtered DB-9 connectors
  • Ground and power planes on the printed circuit board

Efficiently converts 12 VDC input to 3.3 VDC output for Garmin GPS's that have rectangular connectors. Compatibility with a complete line of cables allows it to be used with a wide variety of devices.  For help selecting the right components for your needs.
