FERROXCUBE DATA SHEET TN9/6/3 Ferrite toroids Supersedes data of September 2004 2008 Sep 01Ferroxcube Ferrite toroids TN9/6/3 RING CORES (TOROIDS) Effective core parameters 9.5 0.3 handbook, halfpage SYMBOL PARAMETER VALUE UNIT 1 (I/A) core factor (C1) 5.17 mm 3 V effective volume 102 mm e I effective length 22.9 mm e 2 A effective area 4.44 mm e m mass of core 0.5 g 5.4 0.3 Coating coating PA11 (0.3) The cores are coated with polyamide 11 (PA11), flame retardant in accordance with UL 94V-2 UL file number 3.4 0.25 E 45228 (M). The colour is white. CBW315 Maximum operating temperature is 160 C. Dimensions in mm. Isolation voltage Fig.1 TN9/6/3 ring core. DC isolation voltage: 1000 V. Contacts are applied on the edge of the ring core, which is also the critical point for the winding operation.

Old permeability specification maintained. 2. Due to the rectangular BH-loop of 3R1, inductance values strongly depend on the magnetic state of the ring core and measuring conditions. Therefore no A value is specified. For the application in magnetic amplifiers A is not a critical parameter. L L WARNING Do not use 3R1 cores close to their mechanical resonant frequency. For more information refer to 3R1 material specification in this data handbook. 2008 Sep 01 1609
