Coilcraft Designer's Kit C129 - SMT Wideband RF Transformers TTWB Series These wideband RF transformers provide excellent performance at a very economical price. They come tapped or untapped and are packaged in a low profile, flat top ceramic case that makes them ideal for pick and place operations. They feature 400V isolation and a 500 mA maximum current rating. Operating temperature range is -40C to 85C. Applications include impedance matching, voltage or current transformation, DC isolation, balanced/unbalanced mixing, matching, power splitting, coupling and signal inversion. Coilcraft Designer's Kit C129 contains samples of the values shown.
