Ms. Rocío Arrupe
Severo Ochoa 47,
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 and high sensitivity in low frequency range (1kHz). Those pieces are winding with thin copper wire up to 16μm 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.
The specification chart is a reference guide for the most common required values at working frequencies of 20 kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales deparment for any inquiry.
