TDK Corporation presents the MEM1005PP251T – a new LC filter for EMI suppression. With dimensions of just 1.0 mm x 0.5 mm x 0.35 mm the filters are ideally suited for use in smartphones and base stations. Volume production began in March 2017. The usual method for suppressing interference in the communication frequency bands of smart phones and other devices is to use capacitors or inductances, or a combination of these components. In contrast to discrete solutions, the MEM1005PP251T combines two capacitors and an inductance in the form of a Pi filter in a single component. As a result, 61 percent less space is required and there is a reduction in the overall number of components.
