100 brand new and high quality<br> <br> Features:<br> It is focus on controlling the output loop current by controlling the electric field effect of the input loop.<br> The input voltage of the control input terminal of the MOSFET is extremely small, so its input resistance is large.<br> It uses most carriers to conduct electricity, so its temperature stability is better.<br> The field effect tube has strong radiation resistance;<br> Since it does not have shot noise caused by the electron diffusion of the disordered motion, the noise is low.<br> <br> Specification:<br> Material: Electronic component<br> Size: app.1.5 x 3.5cm/0.59x 1.38in<br> Color: Black<br> Quantity: 1 Set<br> <br> Note:<br> No retail package.<br> Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.<br> Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!<br> <br> Package includes:<br> 5 x Field Effect Tube
