PolySwitch SMD & SMD2 Series


From TE Connectivity, these SMD and SMD 2 Series surface mount Polyswitches are compact and suitable for a variety of computer and electronics applications.

SMT footprints:

• SMD - Hold current 0.3 - 1.25A: 7555 (metric) 2920 (Imperial)

• SMD2 - Hold current 1.5 - 2.5A: 8763 (metric) 3425 (Imperial)

Surface Mount Technology


Resettable fuses are designed for the protection of electrical and electronic circuits against excessive currents. They switch rapidly from a low resistance to very high resistance state under electrical overload or short circuit conditions, and feature automatic reset and return to low resistance state when fault condition ceases and power is removed.

Maintenance free automatic reset for thousands of cycles

Small size and no fuseholder required

Main applications


Security systems

Power supplies and transformers

Power switching devices

Automotive and medical equipment

Instrumentation and control
