SD-R-B Series, Toroidal Cores with Snail-Shaped Case

The KEMET ESD-R-B series solid toroidal cores are designed to use on round cables. The wide range of Manganese Zinc (MnZn) and Nickel Zinc (NiZn) options allows for targeting of specific frequency ranges. The snail-shaped case allows fixing the core in the application to avoid contact with other components.
EMI cores are part of a family of passive components which address the issues of noise or electromagnetic interference (EMI) in circuits or systems.
