Wireless Headsets

As use of wireless headphones and other wireless headsets proliferates, Littelfuse keeps pace with electronic solutions for USB charging, wireless charging, and shock prevention. We specialize in providing thermal protection for batteries and TVS diode arrays for ESD protection. We also offer tactile switches for push button controls and eFuses for combined overcurrent and overvoltage protection.
