Ferrite drum core coils with baked varnish windings Our high-performance HP 3616 ferrite is discribed the side before. The windings of baked varnish coils are made using a special wire. After the coil has been wound it is heated up causing an additional layer of varnish on the wire to melt, bonding the individual windings firmly together. The effect is similar to that achieved with vacuum impregnation, but this process is cheaper for small coils. Baked varnish coils are available with winding diameters from 0.71mm – 1.40mm. All series are identified with a “b” prefix. 3 8 40 hpgr40 4.8 56 hpgr56 5.0 3 5 FERRIT DRUM <strong>COIL</strong>S 40 mm Ø WITH BACKED VARNISH WIRE Specifications: Core material: HP 3616 Tolerance: Max. 3% Electrolyte copper 99.99% pure Dimensions: HPGR 40: 40x38mm (DxH) Centre hole: 5.00mm HPGR 56: 56x35mm (DxH) Centre hole: 4.2mm BHPGR 40 mH <strong>OHM</strong> DRAHT €/Stk 1,00 0,13 1,00 1,20 0,15 1,00 1,50 0,16 1,00 1,80 0,18 1,00 2,20 0,21 1,00 2,70 0,24 1,00 3,30 0,28 1,00 3,90 0,31 1,00 4,70 0,64 0,71 5,60 0,65 0,71 6,80 0,79 0,71 10,00 0,96 0,71 12,00 1,20 0,71 15,00 1,20 0,71 33,00 2,02 0,71 22
