Friday New Product: FETs
Solar botics
July 11, 2014
What we have today are not Fairly Expensive Tortillas or Fortunately Edible Theremins, but Field-Effect Transistors. If you know what it is, I will leave you to explore:
|
1RFZ44N N-Channel FET $2.50 The IRFZ44N is a very powerful useful N-Channel FET, with only 0.0175ohms resistance pushing 20 amperes at 5V! |
 |
FQP27P06 P-Channel FET $0.95 A robust P-Channel FET that is capable of interfacing with most 5V-logic microcontrollers. |
 |
NDP6020P P-Channel FET, --2.5V gate, -20V, 24A max $1.95 An N-channel FET with an extremely low gate voltage which can be controlled by most 3.3V and 5V microcontrollers. |
..and no, these are not even Forcibly Eccentric Tabbies.
