The engineer had found the use of a capacitor on a specific trace would solve a radiated emissions issue. However, placement on the connector where we put the capacitor during engineering work was not a production solution. So, the capacitor which was moved less than 1 inch away from the connector and turned sideways to fit on the circuit board. However, this degraded the … [Read more...]
