2) Thin film resistors
Thin-film resistors are produced by depositing materials with specific resistivity onto the surface of insulating materials using methods akin to evaporation. Typically, ceramic substrates serve as the insulating material for these resistors. Vacuum evaporation and magnetron sputtering are common process methods employed in the fabrication of thin-film resistors. The disparity in materials and fabrication processes between thick film resistors and thin film resistors directly translates to differences in their performance. Thick film resistors commonly exhibit accuracy levels of 10%, 5%, and 1%, with a tendency towards lower accuracy. In contrast, thin film resistors can achieve accuracy levels as precise as 0.01% and 0.1%. Additionally, thick film resistors often struggle with controlling temperature coefficients, resulting in relatively large variations. Conversely, thin film resistors offer the advantage of exceptionally low temperature coefficients, ensuring minimal resistance variations with temperature fluctuations, thereby ensuring stability and reliability. Consequently, thin film resistors find widespread applications across various domains including instrumentation, medical equipment, power supplies, electronic devices, and more.
3) Thermistor
A thermistor serves as a type of sensitive element, categorized based on its temperature coefficient into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC). A defining characteristic of thermistors is their sensitivity to temperature, leading to distinct resistance values at different temperatures. PTC thermistors exhibit higher resistance with increasing temperature, whereas NTC thermistors demonstrate lower resistance under similar conditions. Both types operate as semiconductor devices. A thermistor typically remains inactive over prolonged periods. When subjected to ambient temperature and current conditions within zone C, the thermistor’s heat dissipation approaches parity with its heating power, rendering its operation variable. Under identical ambient temperatures, the thermistor’s response time decreases significantly with rising current levels. In situations where ambient temperatures are relatively elevated, the thermistor exhibits shorter response times, lower maintenance currents, and action currents.
