To know about unknown electronic component

sir

please guide me about the electronic component attached in the image file

 

it's name is:

ED5 or E05

The electronic component in the image you provided was a 50k ohms trimmer resistor. The black printed characters in the component actually represent or define the value of the trimmer resistor. The printed value is *503* which is neither ED5 nor E05 that you had first initially thought which means *50x10^3* ohms or simply *50K ohms*. Most electronic components such as trimmer resistors, ceramic capacitors, surface mount components, etc. are labeled like this especially when its size is too small to print out the whole value of the components for easy and simple labeling of the components.

Hi,

I think you already know that this is a Carbon Film Trimpot Potentiometer. If you want to learn about trimpot, read this http://www.resistorguide.com/trimpot/.
