TC0502
SMD Telecoil 5.1x2.3x2.6 mm (40 mH - 270 mH)
Main characteristics
- Small size
- High sensitivity
- SMD mounting
Typical application
- Hearing aid devices
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.
