EMC Considerations
The circuit and plots in Figure 42 shows a suggested configuration to meet the radiated emission limits of FCC Class A. Actual
performance depends on layout and external components used.
CI1 1 x 0.01 μF/50V, 0603 ceramic capacitor
CI2 2 x 10 μF/50V ceramic capacitor (e.g. Murata GRM32ER71H106K)
CO1 1 x 0.01 μF/25V, 0306 ceramic capacitor (e.g. Murata LLL185R71E103MA01L))
CO2 2 x 10 μF/25V ceramic capacitor (e.g. Murata GCM32ER71E106KA42)
RTrim 6.19K Ω resistor
