Electrical Specifications:
Ihold=Hold current: maximum current device will not trip in 25℃
still air.
Itrip= Trip current: minimum current device will always trip in 25℃
still air.
Vmax=Maximum voltage device can withstand without damage at rated
current(Imax).
Imax=Maximum fault current device can withstand without damage at
rated voltage(vmax).
Pd max= Power dissipated when device is in the tripped state in 25℃
still air environment at rated voltage. Max Time-to-trip=Maximum
time to trip(s) at assigned current.
Rmin=Minimum device resistance prior to tripping at 25℃.
Rmax=Maximum device resistance prior to tripping at 25℃.
R1max=Maximum device resistance one hour after it is tripped at 25℃
Packaging and Storage
Packaging
Bulk,500/1000pcs per bag
Storage
The maximum ambient temperature shall not exceed 40℃. Storage
temperatures higher than 40℃ couldresult in the deformation of
packaging materials. The maximum relative humidity recommended for
storage is70%. High humidity with high temperature can accelerate
the oxidation of the solder plating on the terminationand reduce
the solderability of the components. Sealed plastic bags with
desiccant shall be used to reducethe oxidation of the termination
and shall only be opened prior to use. The products shall not be
stored inareas where harmful gases containing sulfur or chlorine
are present.
Warning:
Operation beyond the maximum ratings or improper use may result in
device damage and possibleelectrical arcing and flame.The devices
are intended for protection against occasional overcurrent or
overtemperature faultconditions and should not be used when
repeated fault conditions or prolonged trip events are
anticipated.Contamination of the PPTC material with certain silicon
based oils or some aggressive solvents canadversely impact the
performance of the devices.Device performance can be impacted
negatively if devices are handled in a manner inconsistent
withrecommended electronic,thermal and mechanical procedures for
electronic components.Operation in circuit with a large inductance
can generate a circuit voltage (L di/dt) above the rated voltageof
the resettable device.
Notes:
The specification is intended to present application.product and
technical data to assist the user in selecting PPTC circuit
production devices,However,users should independently evaluate and
test the suitability of each product.Jinrui makes on warranties as
