With the rapid development of China's economy, people's living standards have been continuously improved, and electronic products have entered the family in large numbers. However, electronic products bring benefits to people while dangerous damage is also endless. Most of the products that bring pe

The editor provides a simple test method that, although not up to the professional level of accuracy, can roughly measure the resistance and accuracy of the thermistor, hope to help everyone. 1. Clip the two lead ends of a standard thermistor on the alligator clip, insert the multimeter into the mul

3. To the Lotus root, also known as the solution Lotus. From the circuit, it can always be distinguished as the source of the drive and the load being driven. If the load capacitance is relatively large, the drive circuit must charge and discharge the capacitor to complete the signal transition. Wh

SMD capacitors, people who know this industry know that patch capacitors are widely used. At the same time, the chip capacitor is used as a passive component. The functions frequently used in the power circuit are: the functions of bypassing, decoupling, filtering and energy storage. The main functi

2. Check if the CBB capacitor from 10pF to 0 01uF is charged, and then judge whether it is good or bad. The multimeter uses R × 1k block. The beta values of the two triodes are all above 100 and the penetration current is small. The red and black test leads of the multimeter are respectively connect

Because it is widely used, we need to understand some common CBB capacitance detection methods. 1. Detect small capacitors below 10pF. The fixed capacitor capacity below 10pF is too small. It can be measured with a multimeter and can only be qualitatively checked for leakage, internal short circuit

The composition principle of the CBB capacitor is actually relatively simple, that is, two parallel strip plates, the middle insulating medium constitutes a core, and each of the two plates has one lead, that is, two electrodes. The CBB capacitor is a polypropylene capacitor, and its main features a

Today, there is a customer consultation editor: "Why does the capacitor burst? We have a burst of capacitors purchased in other homes. The quality of your capacitors is no problem. Will this happen?" Edit here I want to Say, the capacitor bursting is not new, and there are many reasons for this, but

Some customers asked the editor: "Why do you produce the quality of the safety capacitors so good, the yield is so high? And the other manufacturers of safety capacitors that we supply can't do you like this?" So the editor invited customers to our field. The factory visit, the customer came to visi

(4) Marking method of imported capacitors: Imported capacitors generally have six components.The first item: the category is represented by letters:The second item: the two-digit number indicates its shape, structure, packaging method, lead start and relationship with the axis.The third item: the te
