P-channel Power MOSFET - TO-220 Package [25A / 60V] [AF-1794]

Get it by Thursday, Dec 21st

When you need to switch a lot of power, P channel MOSFETs are best for the job. These P-FETs can switch over 60V and 25A (with proper heat-sinking) and are TO-220 package so they fit nicely into any breadboard or perfboard. Heat sinking ...

74AHCT125 - Quad Level-Shifter (3V to 5V) [74AHCT125] [AF-1787]

Get it by Tuesday, Dec 12th

Level shifting chips let you connect 3V and 5V devices together safely. This chip is similar to others in the shop (such as the 74LVC125) except this one is particularly good at converting 3V logic up to 5V. This is in demand especiall...
