Additional Details

The 0402 package size is a standard miniature size for chip resistors and is commonly used in applications where space is limited on the circuit board. The ±5% tolerance indicates the permissible variation in the resistor's actual resistance value. The temperature coefficient of resistance (TCR) specifies the degree to which the resistance changes with temperature variations. The nickel barrier termination ensures excellent solderability and prevents solder leaching during reflow soldering. Thick film resistors are widely used because they offer a good balance between cost, performance, and reliability.

In summary, this resistor is suited for various general-purpose applications, offering a reliable 33kΩ resistance in a small, surface-mountable package.
