Polymeric PTC Reset Fuse 60V 140mA Ih 1812 Concave SMD PPTC Resettable Fuses MSMD014

Polymeric PTC Reset Fuse 60V 140mA Ih 1812 Concave SMD PPTC Resettable Fuses mSMD014

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

Security systems

Power supplies and transformers

Power switching devices

Automotive and medical equipment

Instrumentation and control

Computers and peripherals

Audio visual and telecommunications

1.Performance Specification

Ihold = Hold Current. Maximum current device will not trip in 25°C still air.

Itrip = Trip Current. Minimum current at which the device will always trip in 25°C still air.

Vmax = Maximum operating voltage device can withstand without damage at rated current (Imax).

Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax).

Pd = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.

Rimin/max = Minimum/Maximum device resistance prior to tripping at 25°C.

R1max = Maximum device resistance is measured one hour post reflow.

CAUTION : Operation beyond the specified ratings may result in damage and possible arcing and flame.
