A capacitor is a crucial part of all AC line filters, and much of their performance depends on it. The performance of a capacitor to get rid of unwanted electromagnetic signals is usually referred to as insertion loss. On the following pages, we’ll take a closer look at the questions of electromagnetic noise and insertion loss in electric filters.

Vishay Expands its Low profile, High Current E-Shield Reduced EMI Inductor Series

The devices released today contain the electric and B field associated with EMI in a tin-plated copper integrated shield, providing up to -20 dB of electric field reduction at 1 cm (above the centre of the inductor) when the integrated shield is connected to ground. Featuring high-temperature operation to +155 °C and coplanarity of their four terminals within ≤ 100 µm, the inductors are optimized for energy storage in DC/DC converters up to 2 MHz and provide excellent attenuation of noise in high current filtering applications up to the SRF of the inductor.

How to Suppress Triacs EMI and RFI Noise

Posted by doEEEt Media Group
On March 16, 2020

Noise is generated in all semiconductor devices including triacs. Triacs are used in such power-switching applications as inverter- or motor-control circuits. Triacs and thyristors (silicon-controlled rectifiers, or SCRs) are used in power-switching applications because these can handle high voltages and currents.
