TC0502

SMD Telecoil 5.1x2.3x2.6 mm

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 to12µm 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.
