Humans use sensory organs to obtain information from the outside world, while machines use sensors to study the laws of natural phenomena, production and life. In order to adapt to various situations, sensors are divided into different types. It can be said that sensors are the five senses of a machine, and it is an extension [...]
Due to the restriction of the ESR and heat dissipation capacity, each type of film capacitor has its specific "rated" ripple current value. Under the same terminal voltage, as the frequency increases, the impedance of the film capacitor decreases, the ripple current flowing increases. When the current flowing through the film capacitor reaches the rated current [...]
What is MPLS MPLS is a protocol that uses labels to guide the high-speed forwarding of data messages on the IP backbone network. It was proposed by the IETF (Internet Engineering Task Force, Internet Engineering Service Group). Compared with the traditional IP routing method, it provides a new network switching method, which maps the IP address [...]
Measure the insulation resistance of capacitors,the following points should be noted: (1) A 500 or 1000 volt megohmmeter can be used to measure low-voltage capacitors, and a 2500 volt megohmmeter should be used to measure high-voltage capacitors. (2) The capacitor should be discharged before and after the shaking test to avoid electric shock accidents. (3) When [...]
What is a three terminal capacitor and what are the advantages? Capacitors are divided into electrolytic capacitors, ceramic capacitors, tantalum capacitors and so on. Ceramic capacitors are widely used in mobile smart products, which are divided into three-terminal capacitors and two-terminal capacitors. People often say that three-terminal capacitors have good high-frequency characteristics. As a hardware engineer, [...]
