SMD1812 HF Series Surface Mount PTC Devices
Note on Electrical Characteristics
Vocabulary
Ihold = Hold current: maximum current device will pass without tripping in 23ºC still air.
Itrip = Trip current: minimum current at which the device will trip in 23 ºC still air.
Vmax = Maximum voltage device can withstand without damage at rated current (I max)
Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd typ = Typical power dissipated from device when in the tripped state at 23 ºC still air.
Rmin = Minimum resistance of device in initial (un-soldered) state.
R1max = Maximum resistance of device at 23 ºC measured one hour after tripping or reflow soldering of 260 ºC for 20 sec.
Value specified is determined by using the PWB with 0.030”*1.5oz copper traces.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
Specifications are subject to change without notice.
Polymeric PTC Selecting Guide
Determine the following operating parameters for the circuits:
y Normal operating current (Ihold)
Ɂ Maximum interrupt current (Imax)
y Maximum circuit voltage (Vmax)
Ɂ Normal operating temperature surrounding device (minºC/maxºC)
y Surface Mount Device (SMD)
Ɂ Axial Leaded Device (ALD)
y Radial Leaded Device (RLD)
Ɂ DISC Device
!!
!!
Select the device form factor and dimension suitable for the application:
!!
Ɂ Other Customized Form Factors
!!
!!
Compare the maximum rating for Vmax and Imax of the PPTC device with the circuit in application and make
sure the circuit’s requirement does not exceed the device rating.
Check that PPTC device’s trip time (time-to-trip) will protect the circuit.
Verify that the circuit operating temperature is within the PPTC device’s normal operating temperature range.
Verify the performance and suitability of the chosen PPTC device in the application.
Mechanical Stress
y PPTC devices will undergo a thermal expansion during fault condition. If PPTC devices are installed or placed in an application where
the space between PPTC devices and the surrounding materials (e.g., covering materials, packaging materials, encapsulate materials
and the like) is insufficient, it will cause an inhibiting effect upon the thermal expansion. Pressing, twisting, bending and other kinds of
mechanical stress will also adversely affect the performance of the PPTC devices, and shall not be used or applied.
Chemical Pollutants
y Silicone-based oils, oils, solvents, gels, electrolytes, fuels, acids, and the like will adversely affect the properties of PPTC devices, and
shall not be used or applied.
Electronic and Thermal Effect
y PPTC devices are secondary protection devices and are used solely for sporadic, accidental over-current or over-temperature error
condition, and shall NOT be used if or when constant or repeated fault conditions (such fault conditions may be caused by, among
others, incorrect pin-connection of a connector) or over-extensive trip events may occur.
y PTTC devices are different from fuses and, when a fault condition occurs, will go into high-resistance state and do not open circuit, in
which case the voltage at such PPTC devices may reach a hazardous level.
y Operation over the maximum rating or other forms of improper use may cause failure, arcing, flame and/or other damage to the PPTC
devices.
y Conductive material contamination, such as metal particle, may induce shortage, flame or arcing.
y Due to the inductance, the operation circuits may generate a circuit voltage (Ldi/dt) above the rated voltage of PPTC devices, which
shall not be used under such circumstances.
General
y Customers shall evaluate and test the properties of PPTC devices independently to verify and ensure that their individual applications
will be met.
y The performance of PPTC devices will be adversely affected if they are improperly used under electronic, thermal and/or mechanical
procedures and/or conditions non-conformant to those recommended by manufacturer.
y Customers shall be responsible for determining whether it is necessary to have back-up, failsafe and/or fool-proof protection to avoid or
minimize damage that may result from extra-ordinary, irregular function or failure of PPTC devices.
y Any and all responsibilities and liabilities are disclaimed if any item under this notice of warning is not complied with.
