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. 2. Ring cores in 3E5 are lacquered (polyurethane) and have different dimensions: Outside diameter = 9.3 ±0.4 mm; inside diameter = 5.75 ±0.3 mm; height = 3.25 ±0.3 mm; flame retardant in accordance with “UL 94V-2” ; UL file number E 192048. 3. Ring cores in 3E6 are coated with parylene C and have different dimensions: Outside diameter = 9.0 ±0.2 mm; inside diameter = 6.0 ±0.2 mm; height = 3.0 ±0.15 mm. WARNING Do not use grade 3R1 cores close to their mechanical resonant frequency.
