Description

JK30 series radial leaded PTCs are designed to provide

over-current protection for low voltage (≤30V) applications

where space is not a concern and resettable protection is

preferred.

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.
