JK
Series of Polymer PTC Resettable Fuse
Introduction to the Product (JINKE-Polymer PTC Resettable
Fuse)
JK series of Polymer PTC self-resettable fuse (JINKE-Polymer
PTC Restoring Fuse) is a new-generation of overcurrent protection
product, its function corresponds to the self-resettable and
re-use fuse, use for protecting circuit from damage by high
current .it has some superiorities as self-resettale, high
security, little restoring time, good resistance to strong
current, little volume and so on. The products are classified
into 10 major categories and nearly 100 specifications based
on their rated operation voltage (Operating Voltage: 6v-600v),
holding current (Holding Current:90mA-14A) and shape, they
can be used in communication exchanger, main distributing
frame, computer mouse, keyboard, micromotor, transformer,
audio, battery and other electrical equipment as well as circuits,
to play the role of overcurrent protection.
JK60 Series of Polymer PTC Self-Restoring Fuse Used
for Communication Equipment
The Jk60 PPTC¡¯s rated operating voltage
is 60v, the holding current being 100mA-5A. this series of
resettable fuse apply to the circuits with rather higher rated
operating voltage, for example in lightings, computers, mouses,
keyboards,UPS, fire alarm and security protection systems,
satellite TV reception systems and other testing&measuring
equipments.
