10pcs Toroid Core Inductor Wire Wind Wound mah--100uH 6A RoHS cc
Une partie de la critique a été traduite automatiquement.
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.
Bien emballé, reçu en bon état et très rapide délai de livraison (7 jours calendaires à partir de la commande). La plupart d'entre eux ont été testés à 100uF (photo 2), mais un couple a testé à 90uF (photo 3), ce qui est dans la plage prévue, mais un rappel de ne pas trop se fier aux valeurs nominales. Je trouve ces articles utiles à garder dans mon laboratoire d'électronique amateur, surtout quand je joue avec des convertisseurs cc-cc pour l'énergie solaire, etc.
They are almost all at 100uH which i was not expected.The unexpected was their size which turned out to be really small.
10pcs de bobines à courant élevé pour courant continu/courant continu.
Bon rapport qualité-prix
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?
exactement comme décrit et la livraison rapide! 👌
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.
