Circuit Protection for IoT Wearable Devices

Littelfuse Circuit Protection for IoT Wearable Devices provide protection and are also extremely small in size to be compatible with the small form factor of IoT Wearables. For general purpose circuits (buttons, audio, etc.), the SP1013 and SP1014 are available in 0201 size; for the ultimate in small size, the SP1020 and SP1021 are 01005 size. For high-frequency circuits (RF), the SP3022 is available with 0.35pF and 0201 size.
