Electronics ferrite ferrite

WüRTH WE-CBA SMT EMI Suppression Ferrite Bead product family include 0402, 0603, 0805, 1206, 1806 and 1812 packages. SMDs are AEC-Q200 qualified as part of firm’s automotive electronics portfolio. Devices features Ni-Sn electrodes, high current carrying capacity up to 6A, and operating temperatures from -55 to +125ºC. Ferrites are available in various specifications and are suitable as data line filters and for decoupling the supply voltage. The miniature devices in multilayer technology are soldered directly onto the pcb. Units have good filter characteristics and low RDC. Placed close to the source of interference, maximum impedances around 1000Ω can be achieved even with the smallest package (0402).
