Thanks for the information. After doing some more testing, I am going to set my limits for ITO to housing based on a sampling of products that we received. It seems like the value across the ITO is very consistent, but the value of ITO to case varies widely. The higher ohm values of those...
There is quite a bit of electronics in the gauge, including a microcontroller and associated circuitry that is used to compensate for temperature variances. The specifications for EMI are covered by military specs on the vehicle.
Sorry to be a little vague. It is for a military dashboard application and the EMI shielding is both for emitted and susceptibility issues. We have limits on both which are part of the design specification. We passed EMI testing with our design, but we did have one emission spike which was in...
There are many standards for color. The commercial world uses Pantone. You have to buy into that program to get the color chips, which are usually given to you with the nominal color and a light and dark chip for the range. When viewed in a standardized light booth you can then view if the...
First let me state that I am a mechanical engineer working to EMI shield an electrical instrument gauge. This gauge is much like the oil temperature gauge on a car. The shielding is in the form of a 2" diameter aluminum housing. The front of this housing is ITO coated glass for viewing the...
