Radial Lead Resettable Polymer PTCs

Radial Lead Resettable Polymer PTCs
JK60 Series
Description
JK60 series radial leaded PTCs are designed to provide
over-current protection for low voltage (≤60V) applications
where space is not a concern and resettable protection is
preferred.

I hold= Hold current: maximum current device will pass without tripping in 25°C still air.
I trip= Trip current: minimum current at which the device will trip in 25°C still air.
V max= Maximum voltage device can withstand without damage at rated current (Imax)
I max= Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pdtyp.= Power dissipated from device when in the tripped state at 25°C still air.
R min= Minimum resistance of device in initial (un-soldered) state.
R max= Maximum resistance of device in initial (un-soldered) state.
R 1max= Maximum resistance of device at 25°C measured one hour after tripping.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.

Warning
u This product should not be used in an application where the maximum interrupt voltage or maximum interrupt current in a fault
condition, Operation beyond the maximum rating or improper use may result in device damage and possible electrical arcing
and flame.
u A PPTC device is not a fuse, It is a nonlinear thermistor that limits current, Because under a fault condition all PPTC devices go
into a high resistance state but not open circuit hazardous voltage may be present at PPTC.
u The devices are intended for protection against occasional over-current or over-temperature fault conditions and should not be
used when repeated fault conditions or prolonged trip events.
u In most application, power must be removed and the fault condition cleared in order to reset a PPTC device.
u PPTC devices are not recommended to be installed in applications where the device is constrained such that its PPTC
properties are inhibited, for example in rigid potting materials or Add devices surface coating, Bundled devices ontology, which
lack adequate clearance to accommodate device expansion.
u Contamination on of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the
performance of the devices. For example, Organic solvents to cleaning.
