1900R Series

      The 1900R Series can be described as followings. The 1900R Series is a general purpose range of inductors suitable for low to medium current applications such as power supply and other general purpose filtering designs. 
      The 1901900R Series 0R series is a very good product. If you want to use 1900R Series you must learn about it rightly. Here you can know some features about it. The 41180 has ten features. Such many features may make it hard for you to remember them, but you ought to pay attention to them. The first feature of the 1900R Series is RoHS compliant. The second feature of the 1900R series is radial format. The third feature of the 1900R Series is up to 7.8A IDC. The fourth feature of the 1900R series is 4.7H to 100mH. The fifth feature of the 1900R Series is low DC resistance. The sixth feature of the 1900R Series is PCB mounting. The seventh feature of the 1900R series is fully tinned leads. The eighth feature of the 1900R series compatible with RoHS soldering systems. The ninth feature of the 1900R series is backward compatible with Sn/Pb soldering systems. The last feature of the 1900R series is custom parts available. The above features are what I want to tell you.
      The absolute maximum ratings of the 1900R Series can make you clear of the 1900R series, I am very glad to show you the absolute maximum ratings of the 91311. The first absolute maximum rating of the 1900R Series is operating free air temperature, which range from -40°C to +95°C. In addition, the second absolute maximum rating of the 1900R series is storage temperature range from -40°C to +125°C. although the number of the absolute maximum rating of the 1900R series is only two, they are helpful.
      There are also some notes about the 1900R Series.Let me show them to you. The first note is that maximum DC current occurs when either the inductance falls to 90% of its nominal value or when its temperature rise reaches 30°C, whichever is sooner. 

      At present there is not too much information about 1900R Series.If you are willing to find more about the 1900R series, please pay attention to our web! We will promptly update the relevant information.
