贴片型NTC热敏电阻其成分中不含树脂材料，所以不存在“耐燃级别”这个定义。
In general, the capacitance value measured at 1kHz is 1.3 times that measured at 1MHz.
Restrict the use of six harmful substances, including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
The varistor voltage of the product will decrease, and the leakage current will increase because the grain boundary layer will be damaged after multiple impacts, making it easier for free electrons to transition.
The material constant B value of NTC thermistor is a key parameter, which is calculated by measuring the resistance value at two temperatures. The calculation method is:
In the formula, T is the Kelvin temperature, and R1 and R2 are the resistance values measured by the thermistor at temperatures T1 and T2, respectively. In experiments, the two commonly chosen measurement temperatures are 25 and 50 ℃ or 25 and 85 ℃.
