Additional Details

The 0402 package size is a standard miniature size for chip resistors and is commonly used in applications where board space is limited. The ±5% tolerance indicates the acceptable variation in the resistor's actual resistance value. The temperature coefficient of resistance (TCR) specifies how much the resistance changes per degree Celsius change in temperature. The nickel barrier termination ensures excellent solderability and prevents solder leaching during soldering. These resistors are manufactured using a thick film process, which involves depositing a resistive material onto a ceramic substrate.

This resistor is suitable for applications requiring a small, reliable, and cost-effective 22kΩ resistance value.
