Coil Form (DRWW Type)

IFT Cores Series (Bobbin Cores)  
Outline : 
Core-Tech's Thread cup cores (THP series) are combined with drum cores (DR series) for building up IFT coil and oscillator coil etc...for achieving fine tuning of portable radio. Thread cores (TH series cores) are combined with cup cores (THP series) to build up IFT coils and oscillator achieve frquency adjustment. Pot cores (p core) is combined with thread cores (TH seroes) to build up the IFT coils and OSC coils.
