FERROXCUBE DATA SHEET TX36/23/15 Soft Ferrites Supersedes data of September 2004 2008 Sep 01 Ferroxcube Soft Ferrites TX36/23/15 RING CORES (TOROIDS) Effective core parameters SYMBOL PARAMETER VALUE 36.25 ± 0.9 UNIT Σ(I/A) core factor (C1) 0.919 mm−1 Ve effective volume 8740 mm3 Ie effective length 89.7 mm Ae effective area 97.5 mm2 m mass of core ≈ 40 g Coating 22.75 ± 0.7 The cores are coated with epoxy, flame retardant in accordance with “UL 94V-0”; UL file number E 228348. The colour is white. Maximum operating temperature is 200 °C. ( 0.12) coating EPOXY 15.4 ± 0.6 Isolation voltage DC isolation voltage: 2000 V. Contacts are applied on the edge of the ring core, which is also the critical point for the winding operation. CBW395 Dimensions in mm. Fig.1 TX36/23/15 ring core.

Old permeability specification maintained. 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 AL value is specified. For the application in magnetic amplifiers AL is not a critical parameter. 2008 Sep 01 1725 Ferroxcube Soft Ferrites TX36/23/15 WARNING Do not use 3R1 cores close to their mechanical resonant frequency.
