In summary, while artichokes make a healthy snack, Schaffner’s RT chokes can improve circuit health by offering common mode current compensated inductances, attenuating common-mode, or asymmetric interference signals. It is composed of two or three windings over a ferrite ring core that, when combined with suitable capacitors, are ideal for filtering RFI on PCBs in AC and DC applications. There are a variety of current ratings, from 6A to 20A, available with inductances from 2.5mH to 10mH. The RT series is RoHS compliant and designed to meet global safety standards.
