Part Number: 0431185751 31 OVAL CABLE CORE ASSEMBLY – Digits 1 & 2 = Product Class – Digits 3 & 4 = Material Grade The B dimension is the core inside diameter. 230 (g) + Test frequency •For solid cable cores, see Round Cable EMI Suppression Cores Round cable snap-it™ assemblies are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%. Single turn impedance tests for 31, 43 and 46 material cores are performed on the E4991A/HP4291B Impedance Analyzer. The 61 material parts are tested on the E4991A / HP4291B Impedance Analyzer and 75 material parts are tested on the E4990A Impedance Analyzer. Cores are tested with the shortest practical wire length. A MnZn ferrite designed specifically for EMI suppression applications from as low as 1 MHz up to 500 MHz. This material does not have the dimensional resonance limitations associated with conventional MnZn ferrite materials. Round Cable EMI Suppression Cores Round Cable Snap-Its Flat Cable EMI Suppression Cores Flat Cable Snap-Its **** Characteristic curves are measured on standard Toroids (18/10/6 mm) at 25°C and 10 kHz unless otherwise indicated. Impedance characteristics are measured on standard shield beads (3.5/1.3/6.0 mm) unless otherwise indicated.
