The R150W-2R2 is a type of surface mount resistor, specifically a 150-ohm, 2.2-watt SMT resistor. This resistor has a very low profile, allowing it to be used in applications where space is a premium. The R150W-2R2 has excellent temperature stability, meaning that its performance remains consistent even when subjected to extreme temperatures. This makes it suitable for a wide range of temperature-sensitive applications. Its low profile also makes it ideal for automated pick-and-place machines, making it an efficient and economical component for high-volume production.
