Wurth, WE-CBF, 1206 (3216M) Unshielded Multilayer Surface Mount Inductor with a Ferrite Core, ±25% Multilayer 3mA Idc

SMD Ferrite Beads, also called Multi-layer Chip Beads or Impeders
Can be used as an alternative to sleeve chokes, 6-hole beads or UHF interference suppression chokes
Thanks to the special multilayer design, very small d.c. loss resistances are achieved in decoupling applications, for example in power supplies
Thanks to the materials used, for EMC interference suppression in the frequency range above 100MHz, a high loss resistance is achieved for interference signals
Ferrite beads act as absorbers and do not require an earth connection for the filter function
Minimal suppression of wanted signals
Effective EMC protection attainable directly on the printed circuit board at interference sources or on potentially susceptible equipment
Magnetically screened design prevents perturbing radiation
High packing density
Excellent soldering properties
Ni-Sn electrodes
Suitable for re-flow, wave soldering and bonding
Wide choice of impedance profiles for optimum filter matching
High-current SMD ferrite filters for wideband decoupling of power supply cables (currents up to 6A)
Material Grade: 3W110

EMC interference suppression in oscillators, buses, measuring and data lines
Power supply decoupling
