About this product
A 390 µH axial color-ring inductor rated at 0.5 W (1/2 W), supplied with leads for through-hole mounting. It is used in LC filters, tuned circuits and general noise suppression on small-signal boards where a fixed inductance is needed.

Frequently asked questions
How do I read the inductance value?
The value is marked with color bands using the standard inductor color code, expressed in µH. If the bands are hard to read, measure the part with an LCR meter for an exact value.
Can it be used in high-current power circuits?
The 0.5 W rating suits small-signal and filter use. For high-current power stages, choose an inductor with a higher current rating designed for switching regulators.
