An EMI energy absorber for use with an electrical circuit, such as a hot wire air flow sensor, which has at least one electrical element which exhibits antenna characteristics at a predetermined frequency range for the EMI. The energy absorber includes a component, such as a ferrite bead, which is electrically connected in series with the element of the electrical circuit. This component exhibits a resistance which varies as a function of frequency and has a maximum resistance within the predetermined frequency range. Thus, the component functions to absorb the EMI and dissipate the EMI as heat.
