The recommended land pattern for the SD53-4R7-R is a rectangular pad with a size of 2.5mm x 1.5mm, with a non-solder mask defined (NSMD) pad shape.
The SD53-4R7-R is rated for operation up to 125°C, but derating is required above 85°C. Consult the datasheet for specific derating guidelines.
Handle the SD53-4R7-R by the body, avoiding touching the leads or core. Use ESD protection and avoid bending or flexing the leads during assembly.
The ESR of the SD53-4R7-R is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on similar inductors from Coiltronics.
The SD53-4R7-R is suitable for high-frequency applications up to 1 GHz, but self-resonance and impedance characteristics should be considered. Consult the datasheet and application notes for more information.
