The recommended land pattern for the CR0402-FX-1400GLF 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-1400GLF has a maximum operating temperature of 150°C, but it's recommended to derate the power rating at high temperatures. For example, at 125°C, the power rating is reduced to 0.5 W. It's essential to check the datasheet and consult with Bourns Inc for specific guidance on high-temperature applications.
The CR0402-FX-1400GLF is a general-purpose chip resistor, and its frequency response is not optimized for high-frequency applications. While it can be used up to a few hundred MHz, it's not recommended for high-frequency applications above 1 GHz. For high-frequency applications, consider using a specialized high-frequency chip resistor from Bourns Inc.
The CR0402-FX-1400GLF has a moisture sensitivity level (MSL) 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-1400GLF has a molded package with a protective coating, but it's not designed for use in extremely humid or corrosive environments. If you need a chip resistor for such applications, consider using a specialized chip resistor with a higher environmental rating, such as the Bourns Inc CR0402-FX-1400GLF-HF, which has a higher humidity rating and is designed for harsh environments.
