The recommended land pattern for CR0402-FX-4640GLF 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.
While the CR0402-FX-4640GLF is rated for operation up to 150°C, it's not recommended for use in high-temperature applications above 125°C without derating. Consult the datasheet for derating information and consider using a high-temperature-rated resistor if necessary.
Handle the CR0402-FX-4640GLF by the edges to prevent damage to the resistor body or terminations. Avoid touching the component with bare hands, as the oils from skin can cause damage. Use ESD-safe handling and storage procedures to prevent electrostatic discharge damage.
The CR0402-FX-4640GLF is rated for operation in environments with relative humidity up to 85% at 85°C. However, it's recommended to use a moisture-resistant coating or conformal coating to protect the resistor from moisture ingress in high-humidity applications.
The recommended soldering profile for CR0402-FX-4640GLF is a peak temperature of 260°C, with a dwell time of 3-5 seconds. Avoid using excessive soldering temperatures or dwell times, as this can cause damage to the resistor or its terminations.
