The recommended land pattern for the CR0805-FX-39R2ELF is a rectangular pad with a length of 1.5mm, a width of 0.8mm, and a solder mask clearance of 0.1mm. This can be found in the Bourns Application Note 104, 'Surface Mount Resistor Land Patterns'.
The CR0805-FX-39R2ELF is a general-purpose thick-film chip resistor, and its high-frequency performance may not be optimal. For high-frequency applications, Bourns recommends using their thin-film chip resistors, such as the CF series, which have better high-frequency characteristics.
The CR0805-FX-39R2ELF has a maximum operating temperature of 150°C. While it can tolerate high temperatures, its power rating will derate above 70°C. For high-temperature applications, Bourns recommends using their high-temperature resistors, such as the CR-H series, which are designed for use up to 200°C.
Yes, the CR0805-FX-39R2ELF is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant. Bourns ensures that all their products meet these environmental regulations.
The CR0805-FX-39R2ELF has a moisture sensitivity level (MSL) of 1, which means it can withstand a maximum of 30 days in a humidity-controlled environment before soldering. This information can be found in the Bourns Packaging and Moisture Sensitivity document.
