The purchase of magnetic ring inductance must mention frequently asked questions -

Regarding the raw material prices of inductors, few manufacturers disclose them. Although the prices of inductor raw materials in the market are mostly transparent, sometimes it will inevitably cause some inconvenience to announce the original prices. After all, it is related to the profitability of inductor manufacturers. However, as an inductor manufacturer, we can reveal some gossip. Let’s not talk too much, just take a simple look at the raw material price of a magnetic ring inductor. According to analysis, the cost of this magnetic core is 7-8 cents a piece in our company, which seems not very high, but compared with other manufacturers, such a price is already very high. The lowest price of magnetic core is about 1-2 cents. Therefore, some customers will inevitably face a situation. The price of the inductor obtained by the inductor manufacturer is low, and the magnetic ring inductor submitted for inspection is no problem, but the more used the magnetic ring inductor after delivery, the more problems there will be. After combining the price of the magnetic ring mentioned before, let’s discuss the way here. Regarding the fact that there is no problem with the inductance products submitted for inspection, the inductance manufacturers deliberately produce them in order to ensure that they can be traded or “produce” from other places. commodity. Signing a contract with such a manufacturer may cause problems at the beginning, and then problems continue to arise. This is because, in order to reduce costs, inductor manufacturers quietly replaced the raw materials for inductor production 'a little bit'. Change the magnetic core of the inductor first, and then replace the silk-covered wire of the inductor after re-production for a period of time. In the face of such inductor manufacturers, even if customers conduct statistical surveys on batch inductors, they will basically meet the standards. However, the quality of the inductor of the next batch number also changes differently. The magnetic material can ensure that the sample sent and the delivered inductor are all the same. We can accept the sealed sample test, and the inductor production uses imported raw materials to ensure the consistent quality of the inductor.
