These are wound on a YELLOW ferrite core of T50-6, which is active in transformation within 3 - 40 MHz. As a intended choke the active region is from DC to some 30 MHz. Wound with about 2.7 m enamelled CU-wire; some 157 turns. Tested 3 in my 10pcs batch, and they were all 98 - 102 µH. A good performer. Happy buyer.
Хорошо упаковано, получено в хорошем состоянии и очень быстрое время доставки (7 календарных дней с момента заказа). Большинство из них протестированы на 100 мкФ (фото 2), но пара протестирована на 90 мкФ (фото 3), что находится в пределах ожидаемого диапазона, но напоминание не полагаться слишком много на номинальные значения. Я нахожу эти полезные предметы, чтобы хранить в моей лаборатории электроники, особенно когда я играю с преобразователями постоянного тока для солнечной энергии и т.д.
They are almost all at 100uH which i was not expected.The unexpected was their size which turned out to be really small.
10шт катушек с высоким током для постоянного и постоянного тока.

Inductance (for all ten) is well within specs (two are 97.8 μΗ, all the rest between 99,8 and 102.8 μΗ). To measure them I used a dedicated L/C meter, which has two scales, one for small inductance values, and one for large ones. My MASTECH MS8222H multimeter - which can also measure inductance – in the lower range of 0-2mH gives lower values compared to the ones obtained from the dedicated L/C meter, while for higher values both instruments give almost the same reading. Having checked both instruments with some small coils that had a label with their exact inductance value , I now trust the dedicated one. Exactly like other reviewers have said, for the 6A nominal current I was skeptical, so I decided to measure one of them. Well, the result was above my expectations. After 30 minutes at 3 Amperes DC, it had stabilized to 61 degrees Celcius, which I think is more than acceptable (see photo). I would push it a little further, if my power supply could give me more current, as I guess it can go up to 4 Amperes without problem. Concluding, 10 nice inductors for a very nice price. So, another 5 star. Thank you, Banggood.
Wire Diameter is only 0.55mm, you'd better not use it over 1.5A, but at this price, who cares?
В точности как описано и быстрая доставка! 👌
low price and good accurate 6A seems to be a bit optimistic !
They are nice but look small. Anyways, handy to have some of these. Great for making lc filters.
