Ferrite drum core coils with baked varnish windings<br />
Our high-performance HP 3616 ferrite is discribed the side before. The windings of baked<br />
varnish coils are made using a special wire. After the coil has been wound it is heated up<br />
causing an additional layer of varnish on the wire to melt, bonding the individual windings<br />
firmly together. The effect is similar to that achieved with vacuum impregnation, but this<br />
process is cheaper for small coils. Baked varnish coils are available with winding diameters<br />
from 0.71mm – 1.40mm. All series are identified with a “b” prefix.<br />
