Note on Part Numbering: Digits 1&2 = product class, 3&4 = material grade. The last digit indicates: 1 = not burnished, 2 = burnished, 4 = Parylene coated.
Note on Impedance: Minimum impedance values are specified for frequencies marked with '+'. The minimum guaranteed impedance is the listed typical impedance less 20%.
Note on DC Bias Field: The 'H (Oe)' value is the calculated dc bias field for 1 turn and 1 ampere direct current. The actual dc H field is this value multiplied by the actual NI (ampere-turn) product.
Preferred beads are suggested for new designs due to shorter lead times and ready availability.
The 'C' dimension (bead length) can be modified for specific applications.
The 'Shield Bead Kit' (part number 0199000019) contains a selection of these beads.
