Multifuse® and ChipGuard® Circuit Protection Devices for USB 2.0 and USB 3.0

Bourns' Multifuse resettable fuses and ChipGuard ESD suppressors are used to protect today's powerful new USB interfaces

Image of Bourns' Multifuse and ChipGuard Circuit Protection Devices for USB 2.0 and USB 3.0Bourns Multifuse family of polymer positive temperature coefficient (PPTC) "resettable fuses" are used in a wide variety of circuit protection applications. Under fault conditions, the device resistance will rise exponentially and remain in a "tripped" state, providing continuous circuit protection until the fault is removed. Once the fault is removed and the power cycled, the device will return to its normal low-resistance state.

The ChipGuard MLC and MLU Series have been specifically designed to protect sensitive electronic components from electrostatic discharge damage. The MLC and MLU families have been designed to protect equipment to IEC61000-4-2, Level 4 (±8 kV Contact / ±15 kV Air Discharge) ESD specifications targeted for high speed USB 3.0/USB OTG, HDMI 1.4, DVI or IEEE1394 applications.
