The recommended land pattern for the RFS1317-105KL is a rectangular pad with a size of 3.3 mm x 2.5 mm, with a non-solder mask defined (NSMD) pad shape.
The RFS1317-105KL is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% for every degree above 80°C to ensure reliable operation.
Handle the RFS1317-105KL by the body of the component, avoiding touching the leads or the core. Use a vacuum pickup or tweezers to handle the component during PCB assembly.
The ESR of the RFS1317-105KL is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on the DC resistance and the inductance value.
The RFS1317-105KL is designed for high-frequency applications up to 1 GHz, but the self-resonant frequency (SRF) is around 300 MHz. It's recommended to use a different inductor if the operating frequency is above 300 MHz.
