The 5967001701 is a 67-material-grade toroidal ferrite core designed for signal conditioning and power management applications. It features a ring configuration that maximizes the utilization of intrinsic ferrite material properties, with dimensions of 31.75 mm (A), 19.05 mm (B), and 9.5 mm (C), and a weight of 23 grams. The core exhibits an inductance factor (AL) of 39 nH with a tolerance of +35%, -25%, an effective cross-sectional area (Ae) of 0.59 cm², an effective path length (l) of 7.6 cm, and a core volume (Vc) of 4.5 cm³. The toroid is supplied with burnished edges and can be optionally coated with Parylene C (for cores =9.5 mm OD) or thermo-set plastic coating (for cores =9.5 mm OD), with the plastic-coated variant withstanding a minimum breakdown voltage of 1000 Vrms. These cores are widely used in power input filters, ground-fault interrupters, common-mode filters, and pulse and broadband transformers.
