Many people have doubts about the authenticity of inductance. Especially in the buying process, it can be hard to separate the wheat from the chaff. Today Xiaobian will teach you how to identify the true or false inductance, after reading you will know how to buy!
1: Basic concepts of electronic components
Electronic components are those that convert electrical energy into other forms of energy. It includes resistor, capacitor, inductor coil and power line and other parts. Resistors are generally used to limit current and play a buffer role; Capacitors, on the other hand, are usually used to store charges or signals; The inductor coil is used to regulate the size of the current. 09360082632 price? In circuits, we usually use transistors to control voltage changes, so as to achieve current amplification or control DC output. In this process, the resistor plays a key role. Resistors have two characteristics: one is that they can be made very small, even a few square centimeters; The other is that it can withstand a lot of pressure without generating any heat. Thus, resistors are often used as part of a power designer’s consideration when applied to electromagnetic fields.
2: The method of judging the true or false inductance
1, according to the inductance circuit structure. Inductors commonly used in electronic components include capacitive and resistive types, which are classified into 10uF 2PHA/kWh and 3KV levels according to their capacitance. For the former, the larger the capacity, the better; As for the latter, it may be due to the aging failure of some components and lead to the deterioration of its performance. Numerically, capacitive versus resistive is generally considered to have a higher signal-to-noise ratio. Therefore, when choosing, you can first check whether the parameter description indicates the signal-to-noise ratio requirements. 2. Identification methods Generally speaking, capacitive inductors can be judged by measuring the capacitance. But it takes sophisticated equipment and professionals to accurately detect the capacitance. In addition, many other methods can be used to identify the true and false inductors: (1) by observing the curve of the relation between capacitance and frequency. If the capacitance changes with frequency is large or small, it is fake; On the contrary, if the capacitance increases very little or very slowly with the frequency, it is genuine.
3: How to identify the true and false typical instances
How to identify a typical instance of authenticity? This is a very important question. Many people don’t know what to do, because there are common ways to easily distinguish between true and false inductors. First, you need to determine if they are genuine. If true, it means the products have been certified as having a good reputation. And if it’s not real, it can’t be called authentic, it’s just a fake. Secondly, we should pay attention to the labels on the surface of the goods and the identification on the packaging. If it says “genuine” or “original,” it’s a product made by a real brand owner. In addition, you can also judge whether it is genuine by listening to the introduction of the business. Generally speaking, a good business will take the initiative to show consumers the quality of their products, and a variety of warranty policies are very familiar. So, if you want to buy a thing, be sure to choose a good reputation, after-sales service perfect merchant transaction.
If you want to buy good inductors, learn to distinguish between real and fake inductors. Also pay attention to the brand and model and don’t choose the wrong product.
