2 Typical application
@ _- Hearing aid devices E Q zt This new design is coil with a very stable and high quality ferrite core and tiny size (9 x 1.5 x 2 mm) and high sensitivity in low frequency range (20-40kHz). Those pieces are winding with thin copper wire up to12ym and its inductances range is 260-340 mH. Besides, it has good frequency and temperature behaviour and can be served with “custom” electrics characteristics according requirements of hearing aid devices manufacturers.
