This is a smaller 50x50x10mm fan. The fan has a DC brushless motor, with an operating voltage of 5V, and is rated at 190mA. Keeping the temperature down in your project can often be a necessity, and this fan can definitely help.
Note: As some of you have noticed, the fans that we are receiving are slightly different from the older model. The new fan has the model number Y-Y50101-15B and is rated for 200mA. We’re working on getting pictures updated and digging up a datasheet. The new fan, however, is nearly identical.
