2.5cmx1.5cm Heat Sink(Pack of 5) A heat sink transfers thermal energy from a higher temperature device to a lower temperature fluid medium. The fluid medium is frequently air, but can also be water, refrigerants or oil. If the fluid medium is water, the heat sink is frequently called a cold plate. When the airflow through the heat sink decreases, this results in an increase in the average air temperature. This in turn increases the heat sink base temperature. And additionally, the thermal resistance of the heat sink will also increase. The net result is a higher heat sink base temperature. The increase in heat sink thermal resistance with a decrease in flow rate will be shown later in this article. The inlet air temperature relates strongly to the heat sink base temperature.  If there is no airflow around the heat sink, energy cannot be transferred.

2GT 20 teeth pulley wheel for Belt 6mm Perlin passive idler pulley wheel bore 5mm This Aluminum GT2 Timing Idler Pulley wheel For 6mm Belt 20 Tooth 5mm Bore pulley works with GT2 6mm wide timing belt; it will work perfectly with GT2 pulley-belt sets we are selling in our store. This idler is a good match for 20T GT2 driving Timing Belt Pulley. Many DIY 3D printer makers are using idler pulleys based on 3D Printed wheels. Inaccurate printed idler decrease printing quality and create vibrations since the outside diameter of the idler is not concentric to the rotation axis. Other makers are using double bearings with stationary washers clamped from both sides. This solution is not ideal since there is friction between the moving belt to the stationary washers. Our Dual BB Aluminum Idler Pulley is a simple and inexpensive solution to this problem. Check out our entire range of Timing Belt & Pulley .

2N2222A NPN Transistor (Pack of 5) The PN2222A is a common NPN BJT used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, and medium voltage, and can operate at moderately high speeds. 2N2222A is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. The 2N2222 NPN Transistor is made in the TO-18 metal can as shown in the picture. Replacements are commonly available now in the cheaper TO-92 packaging, where it is known as the PN2222 or P2N2222, which has similar specifications except for the lower maximum collector current. read more : What is a 2N2222A Transistor & Its Working Applications: This transistor can be used as a switch for automatically switch ON/OFF any appliances.
