Schaffner RN218 series high-performance common mode chokes

Schaffner has announced the RN218 series of high-performance common mode chokes, specifically developed to meet the highest impedance characteristics. Common mode chokes suppress common mode or asymmetric noise generated by any kind of switching electronic device, including switch mode power supplies or other kinds of transistor driven logic. The common mode choke is at the centre of any design-in EMC filter and most beneficial in developing the perfect solution for customer specific filter designs in terms of cost, performance and size. Based on the different families available, typical applications include; (switch mode) power supplies, information and communications technology, medical devices and motor drives.
