The recommended PCB land pattern for the S1008-222J is a rectangular pad with a size of 1.27 mm x 1.27 mm (0.05 in x 0.05 in) with a 0.5 mm (0.02 in) spacing between pads.
The S1008-222J is rated for operation up to 125°C (257°F). However, it's recommended to derate the inductor's current rating by 1.5% for every degree above 80°C (176°F) to ensure reliable operation.
The S1008-222J has a shielded construction, which reduces electromagnetic interference (EMI). However, it's still recommended to follow good PCB design practices, such as keeping the inductor away from sensitive components and using a ground plane to minimize EMI.
The SRF of the S1008-222J is not explicitly stated in the datasheet. However, based on the inductor's physical characteristics and similar products, the SRF is estimated to be around 100-150 MHz.
Yes, the S1008-222J is suitable for switching regulator applications due to its low core loss and high saturation current rating. However, ensure that the inductor is properly sized for the specific application and follows the recommended PCB layout guidelines.
