The recommended land pattern for the CR0402-FX-1821GLF is a rectangular pad with a size of 0.5 mm x 0.25 mm, with a non-solder mask defined (NSMD) pad shape. This is to ensure proper soldering and to prevent solder bridging.
The CR0402-FX-1821GLF has a maximum operating temperature of 150°C. While it can tolerate high temperatures, it's essential to consider the derating curve and ensure that the resistor is not subjected to temperatures above the recommended maximum. Additionally, the resistor's power rating should be considered to prevent overheating.
To prevent damage during PCB assembly, handle the CR0402-FX-1821GLF by the edges, avoiding touching the resistor body or terminations. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage. Additionally, ensure that the PCB is clean and free of debris to prevent contamination.
The CR0402-FX-1821GLF has an MSL rating of 1, which means it can withstand a maximum of 30 days at 30°C and 60% relative humidity before soldering. It's essential to follow proper storage and handling procedures to prevent moisture absorption.
The CR0402-FX-1821GLF is designed to withstand normal PCB assembly and handling vibrations. However, it's not designed for high-vibration or high-shock applications. If your application requires resistance to extreme vibrations or shocks, consider using a more robust component or consulting with a Bourns Inc. representative for guidance.
