SMD Telecoil 5.1x2.3x2.4 mm (40 mH - 270 mH) oO e Main characteristics 3 - Small size 3 - High sensitivity = - SMD mounting 5 Typical application a - 2 jearing aid devices A Ps c e This new design is coil with a very stable and high quality ferrite core and tiny size (5.1 x 2.3 x 2.4mm) and high sensitivity in low frequency range (20-40kHz). Those pieces are winding with thin copper wire up to1 2pm and its inductances range is 40-270mH. Besides, it has good frequency and temperature behaviour and can be served with “custom” electrics characteristics according requirements of hearing aid devices manufacturers.
