The recommended land pattern for the CR2512-JW-301ELF is a rectangular pad with a size of 2.5mm x 1.2mm, with a 0.5mm x 0.5mm thermal pad in the center. The pad should be solder-mask defined and have a non-solder-mask-defined (NSMD) pad for the thermal pad.
The CR2512-JW-301ELF is rated for operation up to 150°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 125°C. It's also important to ensure that the component is properly cooled and that the PCB is designed to handle high temperatures.
During reflow soldering, the CR2512-JW-301ELF should be exposed to a peak temperature of 260°C for no more than 10 seconds. The component should be placed on a solder paste with a melting point of 183°C to 220°C, and the reflow profile should be optimized to prevent thermal shock.
Yes, the CR2512-JW-301ELF is compatible with lead-free soldering. It's designed to meet the requirements of the RoHS directive and can be soldered using lead-free solder alloys with a melting point of 217°C to 220°C.
The CR2512-JW-301ELF should be stored in a dry, cool place with a relative humidity of 50% or less. It should be handled with anti-static precautions, such as using an anti-static wrist strap or mat, and should not be exposed to direct sunlight or moisture.
