Transformers or mutual inductances suitable for handling frequencies considerably beyond the audio range (resonant circuits H03H)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Transformers or mutual inductances suitable for handling frequencies considerably beyond the audio range

CPC: Transformers or mutual inductances suitable for handling frequencies considerably beyond the audio range (resonant circuits H03H)

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

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)

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
