Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Fixed transformers or mutual inductances of the signal type > Transformers or mutual inductances suitable for handling frequencies considerably beyond the audio range > Broad-band transformers, e.g. suitable for handling frequencies well down into the audio range
CPC:
Fixed transformers or mutual inductances of the signal type (H01F36/00 takes precedence) > Transformers or mutual inductances suitable for handling frequencies considerably beyond the audio range (resonant circuits H03H) > Broad-band transformers, e.g. suitable for handling frequencies well down into the audio range
No child classifications to compare. This is a leaf node in both IPC and CPC.
