Long power inductor easy _ _ Long-yu electronic inductor

Inductance bad judgment 1, inductance measurement: The multimeter diode file buzzer, the lead on the two pins, see multimeter reading. 2, good or bad judgment: For Chip inductors should read zero at this time, if the multimeter reading too large or infinite, said inductor damage. For more turns inductor coil inductance Long handy, smaller diameter coil when the readings will reach tens to several hundreds, the DC resistance of the coil typically only a few ohms. Damage manifested as hot or obviously damaged Dalang magnetic inductance coil, coil inductance if not severely damaged, but can not be determined, the available inductance meter to measure its inductance or replace the law to judge. Top 470 digital inductance is what is meant inductance figure what is meant by the top 470, 470 is an abbreviation notation, because the body is small, Long inductance inductance coil election Which can not be marked complete specification, use an acronym The representation for encoding specification which represents keep abreast of sheet resistance is the same, 470 represent 47 is a real professional Long coil, back 0 0 0, meaning that there is no unit is UH, inductance top 470 refers to the inductance of the inductor inductor 47UH Dalang easy to use _ power _ Long-yu electronic inductor provided by the Dongguan City Yu Electronics Co., Dongguan City Yu Electronics Co., Ltd.
