ON Semiconductor has a range of common mode filter (CMF) devices with integrated electrostatic discharge (ESD) protection for noise suppression in signals.

These are silicon filters which the supplier said will suppress EMI to deeper levels and at higher frequencies than ceramic- or ferrite-based alternatives.

The EMI2121 single pair CMF, EMI4182 dual pair CMF and EMI4183 triple pair CMF all offer a common mode rejection of 15dB (typical) at 500MHz and an insertion loss of only 1.0dB (typical) at 500MHz.

Their high differential mode bandwidth cutoff frequency ensures high levels of signal integrity.

The devices feature integrated ESD protection that meets a peak discharge of 15kV per the IEC61000-4-2 standard.

They support an operating temperature range of −40 ⁰C to +85 ⁰C, and each have a clamping voltage of 32V.
