FAQ:
- Q1: What is PPTC thermistor?
- A1: PPTC thermistor is a resettable fuse with brand name LINKUN,
model number PPTC resettable fuse 250V 1A, place of origin
Dongguan, Guangdong, China. It is a device that can provide short
circuit protection and over current protection.
- Q2: How does PPTC thermistor work?
- A2: When the current exceeds the maximum rated current, the PPTC
thermistor will trip and begin to increase in resistance, cutting
off the current. When the current drops below the maximum rated
current, the PPTC thermistor will reset and return to its
low-resistance state.
- Q3: What is the advantage of using PPTC thermistor?
- A3: The advantage of using PPTC thermistor is that it can provide
short circuit protection and over current protection. It can reset
automatically after the over current condition is released and can
be used multiple times.
- Q4: What is the maximum rated current of PPTC thermistor?
- A4: The maximum rated current of LINKUN PPTC resettable fuse 250V
1A is 1A.
- Q5: What is the temperature range of PPTC thermistor?
- A5: The temperature range of LINKUN PPTC resettable fuse 250V 1A is
-40°C to +85°C.
