Common precautions must be mentioned in the purchase of magnetic ring inductance

Few manufacturers have leaked the price of raw materials for the production of magnetic ring inductors. Although most of the prices of inductor raw materials on the market are completely transparent, sometimes it will inevitably cause some inconvenience to announce the original price. After all, this is about the profit of magnetic ring inductor manufacturers. However, as the editor of the inductor manufacturer, I can leak some gossip. We won't talk much, let's take a simple look at the raw material price of a magnetic ring inductor. First, let's talk about the core price of a magnetic ring inductor. The core of a 6*8 magnetic ring inductor is For example, the cost of this magnetic core is 7-8 cents a penny in the editor's company, which does not seem to be very high, but relative to other manufacturers, the price is already very high. In the manufacturing industry The lowest price of this core is about 1-2 cents. Therefore, some customers will inevitably deal with a situation. The inductor manufacturer's price is low, and there is no problem with the magnetic ring inductance submitted for inspection. According to the price of the magnetic ring mentioned before, let's discuss the way here. There is no problem with the inductance products submitted for inspection. The inductance manufacturer deliberately produced it in order to ensure the transaction volume or 'produced' it from other places. commodity. Signing a contract with such a manufacturer will not cause problems in the initial stage, and then the magnetic ring inductance will continue to have problems. This is because, in order to reduce costs, inductor manufacturers quietly replace the raw materials for inductor production 'a little bit'. First change the magnetic core of the inductor, and after reproducing it for a period of time, the silk-covered wire of the inductor is also removed and replaced. In response to such an inductor manufacturer, even if the customer conducts a statistical survey on the batch number of inductors, there will be a situation where all the basic standards are met. However, the quality of the next batch of inductors will change differently.
