The MR04X150 JTL with Thick Film Resistors - SMD 0402 15R 5% Lead Free, manufactured by Walsin, is a type of thick film chip resistor with an 0402 inch package. This type of chip resistor is a SMD, or Surface Mount Device, meaning that rather than being soldered into a circuit board like through-hole components, it is soldered on the top side of the circuit board. This particular chip resistor has a resistance value of 15 ohms, a tolerance of 5%, and is lead-free. It is suitable for a variety of different applications, such as switching power supplies, motor controllers, and notebook computers.
