Inductance Meter Talking Electronics

INDUCTANCE METER. One of the most difficult items to measure is an inductor. This is mainly due to few multimeters having an inductance feature and the size, shape and number of turns does not give any indication of the value of the component. Of course you can tell if it is micro

Choosing and Using Ferrite Beads Technical Articles

Ferrite saturation reduces the bead's peak impedance and shifts the impedance curve toward higher frequencies, as shown in the following plot from Murata To reduce the effects of core saturation, ensure that your bead's rated current is at least 50% (preferably )

How to Use Crossover Inductors in DIY Loudspeakers

The air cored centre may also be substituted for a Ferrite core in which case it becomes a ferrite inductor. Furthermore, the whole bobbin may be constructed from ferrite, making it also a Ferrite Inductor. For loudspeaker crossovers / audio use, most inductors fall within an inductance range of 10mH (milli-henries) to around 0.1mH.

Powdered-Iron and Ferrite Materials for Inductor Cores

Given 1.2-µH inductor designs with an EIR9.5 core size, the high B SAT ferrite-core material will saturate at 18 A versus the high-flux material saturating at 22 A. Fig. 2 shows inductance versus current at 25°C. The equivalent saturation performance in a ferrite part would require the core package to be 50% larger than the high-flux design.

Likewise, the DC input to the inverter (at the inverter end) and the AC inverter output (at the inverter end) must also have ferrite cores. The DC cables are run TOGETHER through the ferrite cores and the AC output (hot, neutral, ground) are run TOGETHER through the ferrite cores. Use more than one turn through the center hole if possible.

Notes on Calculating the Inductance of a Ferrite Rod

The inductance factor (AL) is not a constant; it depends on the length of the coil. As the coil length decreases, the value of AL increases. The inductance factor can be approximately found by at least three methods (I like the third one) a.) One method is to use the "ferrite rod antenna equation".
