WBC Series Image

The WBC Series from CoilCraft are Wideband Transformers with bandwidths from 150 kHz to 1200 MHz. They have an impedance ratio of up to 1:16 and an insertion loss of less than 2 dB. The transformers have a ferrite core and are available in tapped or untapped configurations. They can handle an input power of 0.25 W and have a current rating of up to 250 mA. These AEC-Q200 Grade-3 qualified transformers are suitable for use as impedance/isolation transformers and for balanced to unbalanced (balun) conversion. They are available in small surface-mount packages that measure 4 x 4 mm with tin-silver-copper over silver-platinum-glass frit terminations (other terminations available at additional cost). The transformers are also available in custom versions.
