Description:
This is Thermistor 100k NTC with 1 Meter Cable Temperature Sensor for 3D Printer Reprap (NTC B3950 100K Thermistors 1% with Cable). The thermistor is a thermally sensitive resistor known for exhibiting a large change in resistance with only a small change in temperature.
Positive thermal coefficient (PTC) will increase in resistance with an increase in temperature, negative ones (NTC) will decrease. But the formula in practice is not linear, so sometimes an accurate table of measurements is better than the linear formula. These measurements can usually be found in the datasheet that accompanies the thermistor.
Features:
- Fastest response time and high accuracy
- Better Stability, as the chip is welded with leads by the alloy soldering process
- High resistance and mechanical strength
- Small size, lightweight and cheap
- Mass production for high accurate element
- Operation temperature range: -50 to +260 degrees Celsius
- Usable in high-temperature and high-moisture environments
Application:
- Temperature sensors
- Electronic thermometers and eternity calendar
- Temperature compensation
- Household appliances ( air conditioners, microwave ovens, electric fans, electric heaters)
- Industrial, medical, environmental protection, weather, and food processing equipment
- Medical instrument
Characteristics:
- Resistance value: R（25°C）=100K±1%
- B Value: B=3950±1% (calculated from resistance value at 25°C and 50C)
- Insulation resistance 50MΩ or over by DC500V megger (between the glass and lead wire)
- Thermal time constant (τ): τ≤10～17s (in still air)
- Operating temperature range:-50~+260℃
Package included:
- 1 x NTC B3950 100K Thermistors 1% with Cable
