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. 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 Ferroxcube Ferrite toroids TN9/6/3 Tag plate General data PARAMETER SPECIFICATION Tag plate material liquid crystal polymer (LCP), glass reinforced, flame retardant in accordance with “UL 94V-0”; UL file number E54705 Solder pad material copper-tin alloy (CuSn), tin (Sn) plated Maximum operating temperature 155 °C, “IEC 60085”, class F Resistance to soldering heat “IEC 60068-2-20”, Part 2, Test Tb, method 1B: 350 °C, 3.5 s Solderability “IEC 60068-2-20”, Part 2, Test Ta, method 1: 235 °C, 2 s 13 max. 1.75 max. 1.8 handbook, full pagewidth 2.8 14.7 max. 10.8 min. 12 11 2 1.8 3 0.8 0.3 CBW284 45° 9 Dimensions in mm. 3 Fig.2 TN9/6/3 tag plate (SMD); 8-solder pads.
