Wideband RF Transformers

Wideband transformers

Coilcraft CPS offers surface mount wideband transformers for critical product applications.
These miniature transformers are available in a variety of untapped and tapped configurations.

They feature:

  • 300 V interwinding isolation,
  • 1/4 Watt input RF power rating,
  • 250 mA current rating.

Typical applications are as impedance or isolation transformer, and they can also be used for balanced to unbalanced (balun) conversion.
