Q: What is the LINKUN PPTC thermistor?
A: LINKUN PPTC thermistor is a resettable fuse with 250V 1A voltage
and current ratings, which is manufactured in Dongguan, Guangdong,
China. Q: What are the advantages of LINKUN PPTC thermistor?
A: LINKUN PPTC thermistor is highly reliable, has excellent circuit
protection capability, automatic reset feature, and low cost. Q: How does LINKUN PPTC thermistor work?
A: When the current overloads, the PPTC thermistor will heat up and
expand, which results in a rapid rise in resistance to stop current
flow. When the current returns to a normal level, the LINKUN PPTC
thermistor will cool down and reset itself. Q: What is the application of LINKUN PPTC thermistor?
A: LINKUN PPTC thermistor is widely used in all kinds of electronic
circuits, such as charging protection for mobile phones, laptops,
power banks, and smart home appliances. Q: What is the temperature range of LINKUN PPTC thermistor?
A: LINKUN PPTC thermistor has a normal operating temperature range
of -40°C to +125°C.
