Printed: 2013-07-03
Part Number: 0431163951
Frequency Range: Lower & Broadband Frequencies 1-300 MHz (31 material)
Description: 31 FLAT CABLE CORE ASSEMBLY
Application: Suppression Components
Where Used: Cable Component
Part Type: Flat Cable Snap-Its
Mechanical Specifications
Weight: 110.000(g)
Part Type Information
Flat cable snap-its for use on multi-conductor flat cables to suppress common-mode conducted EMI from 1MHz to hundreds of MHz. These
flat cable snap-its are available in two ferrite materials, 31 and 43. The polypropylene cases are meeting the RoHS restrictions
of hazardous substances and have a flammability rating of UL94 V-0.
-Flat 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%.
-Centered, single turn impedance tests on the 31 and 43 material parts are performed on the 4193A Vector Impedance Analyzer. Cores
are tested with the shortest practical wire length.
-The 'Expanded Cable and Suppressor Kit' (Part number 0199000005) contains several flat cable snap-it assemblies.
-Explanation of Part Numbers: Digits 1 & 2 = product class and 3 & 4 = material grade.

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.
