Small coils (toroid inducer) from 330 uH to 3 Amperes. Since I'm doing a lab inductive box to perform bench tests, I invested in this 5-piece kit. I can also sell them or use them to repair or modify any circuit. Always needed in the workshop or laboratory, I tested a coil and it was accordingly, received without delays and well packaged, I recommend this article. Thank you, Bangood.

Pequenas bobinas (inductor toroid) de 330 uH para 3 Amperes. Como estou a fazer uma box indutiva de laboratório para realizar testes de bancada investi neste kit de 5 peças. Também as posso vendar ou utilizar para reparar ou modificar algum circuito. Faz sempre falta na oficina ou laboratório, testei uma bobina e estava em conformidade, recebido sem atrasos e bem embaladas, recomendo este artigo. Obrigado Bangood.

Inductance (for all five) is well within specs (smaller value is 319 μΗ, while the other 4 are between 324 and 328 μH, which is more than fine). I also tested one of them for the current that can withstand. After 30 minutes at 2 Amperes DC, it has stabilized to 99 degrees Celsius (which I think is acceptable), when current was decreased to 1.5 Amperes DC, it cooled down and stabilized to 67 degrees Celsius, which I think it is more than fine (see photos for both tests). I would not push it to its nominal value of 3 Amperes, yet I consider that for the price we pay, these are more than adequate. So 5 star for this product. Thank you, Banggood.
