Designed to connect across the AC input of a line powered device, Illinois Capacitor's new "THB" Series capacitors suppress radio frequency interference (RFI) in products that must operate ...
Some surface-mount capacitors exhibit acoustic noise when operated at frequencies in the audio range. A recent design uses 10-μF, 35V X5R 1206 ceramic capacitors that produce noticeable acoustic noise ...
The MEXY metallized polyester Class X2 and Class Y2/X2 film capacitors suit across-the-line and line-to-ground interference-suppression applications. Available in values from 0.001 to 2.2 µF, the ...
Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design ...
When electronic devices receive strong electromagnetic waves, unwanted electric currents can be induced in the circuit, interfering with intended operations. EMI filters deliver superior EMI ...
