1.5k ohm 1% 1/4 Watt Resistor (Box of 5000) - MFR 33K The Drain and Source are

The Drain and Source are connected when a signal is applied to the Gate terminal

Software and Hardware Write-Protect

Higher switching frequencies will allow you to design supplies with considerably wider control-loop bandwidth which can be provided by IRFB38N20

Tinned Copper wires are desirable for soldering as they make connections and soldering is an easy task given tin is a primary component in soldering

Because of its isolated mounting hole

1.5k ohm 1% 1/4 Watt Resistor (Box of 5000) - MFR 33K The Drain and Source areThese are Metal Film Resistor with a value of 1. 5k ohm 1 4W and tolerance of 1%. These Axial resistors are cylindrical in shape with copper plated steel leads extending from each end. Metal Film Resistor limit the flow of electric current using a Metal Film. The printed colour code rings, which are Brown, Green, Black, Brown, Brown for these 1K5 resistors, make it easy to identify the value of these resistors. Specification Resistance Value 1. 5k ohm
