RT Series Current-Compensated Chokes

Schaffner EMC has expanded its already successful product portfolio of current-compensated chokes. The RT series chokes are available with horizontal and vertical mounting options and in 2-line and 3-line versions.  Standard current ranges are from 6 A to 20 A with voltages up to 600 VAC. The product range enables developers to integrate excellent saturation behavior together with high common mode performance on to a PCB. 

The wide range of 24 different combinations of layout, mounting positions, and current-inductance ratings makes the series a great fit for solar inverter and switch mode power supplies (SMPS). The saturation behavior and the ability to apply forced cooling to increase maximum possible current are useful for motor drive (VSD) applications up to 32 A. 

In addition to this exemplary application, RT chokes can be used as a base for all EMC filter designs up to 20 A (32 A forced cooling).

Schaffner’s RT chokes comply with RoHS and REACH requirements and with their open-frame construction and UL part lists are simple to certify to the most important global safety norms, including UL and ENEC.
