Additional Details

The 0402 package size is a standard miniature size, making it suitable for applications where space is at a premium. The ±5% tolerance allows for slight variations in the actual resistance value. The temperature coefficient of resistance (TCR) indicates the stability of the resistance over temperature changes. The nickel barrier termination ensures good solderability and prevents solder leaching during reflow soldering. These resistors are manufactured using a thick film process, providing a good balance of cost and performance.

This resistor is often utilized in various general-purpose applications requiring a small, reliable, and cost-effective 20kΩ resistance.
