Additional Details

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

This part is suitable for general purpose applications where a small, reliable, and cost-effective resistor is needed.
