3.2 TWS Wireless Bluetooth Earphone Electrostatic Surge Protection Solution
Due to the small working IPP and compact size of headphones, it is recommended to use the self-resetting fuse part number SMD0603P010 manufactured by Leiditech Electronics. This component can effectively protect against excessive IPP and overheating issues in the charging case.
For electrostatic discharge (ESD) protection, the device LC0542T5 is recommended, which can adequately meet the ESD protection needs for VBUS and IO interfaces.
These recommendations comply with IEC 61000-4-2 standards at Level 4, providing protection against contact discharge up to 14 kV and air discharge up to 17 kV.
