Additional Details

The 0402 package is a miniature standard for surface mount resistors, ideal when space is limited. A ±5% tolerance means the actual resistance can vary slightly from the stated 150Ω. The temperature coefficient of resistance (TCR) specifies how much the resistance changes with temperature variations. The nickel barrier termination guarantees good solderability and prevents solder dissolution during soldering. These resistors utilize a thick film process, depositing a resistive layer on a ceramic base.

This resistor is a good choice for general-purpose uses where a small, reliable 150Ω resistor is required.
