Part Type Information
Fair-Rite offers a broad selection of cost effective multi-layer chip beads to suppress conducted EMI signals. Chip beads can be used
in an array of devices such as cellular phones, computers, laptops, pagers, etc. The small package sizes accommodate automated placements
and allow for a dense packaging of circuit boards. Chip beads are 100% tested for impedance and dc resistance. They are available in
standard, high and GHz signal speeds. The multi-layer chip beads are organized by increasing package size and current carrying capacity.
-All multi-layer chip beads are supplied taped and reeled, if required bulk packed chip beads can be provided.
-The impedance values listed are typical values. The nominal impedance with a ± 25% tolerance is specified for the + marked 100 MHz.
Chip beads are measured for impedance on the HP 4291A and fixture HP 16192A.
-Chip beads have plated contacts, 100% tin over a nickel undercoating. They can accommodate both reflow and wave soldering technologies.
-The suggested land patterns are in accordance to the latest revision of IPC-7351.
-Recommended storage and operating temperature range is -55°C to 125°C.
-Our 'Chip Bead Kit' (part number 0199000018) is available for prototype evaluation.

Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The actual dc H field in
the application is this value of H times the actual NI (ampere-turn) product. For the effect of the dc bias on the impedance of the bead material,
see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression.
A ½ turn is defined as a single pass through a hole.
