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 A L is not a critical parameter. WARNING Do not use 3R1 cores close to their mechanical resonant frequency. For more information refer to “3R1” material specification in this data handbook. 2003 July 24 2 Ferroxcube Ferrite toroids TN36/23/15 Properties of cores under power conditions B (mT) at CORE LOSS (W) at H = 250 A/m; f = 25 kHz; T = 100 ° C f = 25 kHz; ˆ = 200 mT; B T = 100 ° C f = 100 kHz; ˆ = 100 mT; B T = 100 ° C 3C90 ≥320 ≤0.96 ≤0.96 3F3 ≥320 GRADE 2003 July 24 ≤0.95 3 f = 400 kHz; ˆ = 50 mT; B T = 100 ° C ≤1.7 Ferroxcube Ferrite toroids TN36/23/15 DATA SHEET STATUS DEFINITIONS DATA SHEET STATUS PRODUCT STATUS DEFINITIONS Preliminary specification Development This data sheet contains preliminary data.
