Shield Bead Ferrite Chokes
The Prem SPG-100 and SPG-101 are designed to attenuate EMI and other unwanted signals in a circuit without contributing to power losses at lower frequencies or DC. These two units offer vertical-mount arrangement. Impedances range from 20 Ω to 50 Ω and are obtained over frequencies ranging from 1.0 MHz to 400 MHz. Currents are limited only by the #22 AWG or #24 AWG tinned copper wire used in construction. Each core is 0.235 inches diameter by 0.400 inches long with leads extending radially about 1.0 inches from the end.
