Thermistor Kits consist of NTC, PTC, or a combination of NTC & PTC thermistors that exhibit variations in resistance in response to temperature fluctuations. These kits are available in through-hole, surface mount, eyelet, or probe configurations, offering a range of values and quantities. The kits can range from 6 values (1 piece each) to 5725 pieces (mix of 109 values with varied quantities) and cover temperature ranges from -55°C to 170°C.
