Bourns recommends a land pattern with a minimum pad size of 1.3 mm x 1.3 mm and a maximum pad size of 1.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape.
The 2027-09-SM-RP is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
Handle the component by the edges, avoid touching the pads or the resistor body, and use a no-clean or low-residue soldering process to prevent damage or contamination.
The 2027-09-SM-RP has a typical lifespan of 10,000 hours at 70°C with a 100 mΩ resistor value, but this can vary depending on the application, operating conditions, and environmental factors.
The 2027-09-SM-RP is not recommended for use in high-humidity or moisture-rich environments, as it may lead to corrosion or degradation of the resistor. If used in such environments, ensure proper sealing or conformal coating of the PCB.
