Surface Mount Wideband RF Transformers
These wideband RF transformers provide excellent perfor-
mance 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 400 V isolation and a 500 mA maximum current
rating. Operating temperature range is -40° to +85° C.
Applications include impedance matching, voltage or cur-
rent transformation, DC isolation, balanced/unbalanced
mixing, matching, power splitting, coupling and signal
inversion.
